A01.19 - Steel Sheet and Strip

ABSTRACT
This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet. The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process. Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness requirements. Bend tests shall be conducted in accordance with requirements specified.
SCOPE
1.1 This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet, with specific temper, with specific edge or specific finish, and in sizes as follows:    
Width, in.  
Thickness, in.    
Over 1/2 to 23 15/16  
0.300 and under    
Over 12.5 to 600 mm  
7.6 mm and under  
1.2 Cold-rolled strip is produced with a maximum specified carbon not exceeding 0.25 percent.  
1.3 Strip tolerance products may be available in widths wider than 23 15/16 in. [600 mm] by agreement between purchaser and supplier. However, such products are technically classified as cold rolled sheet. The tolerances, finishes, tempers, edges, and available widths and thicknesses differentiate cold rolled strip from the product known as cold rolled sheet which is defined by Specification A568/A568M and from cold rolled high carbon strip which is defined by Specification A682/A682M.  
1.4 For the purpose of determining conformance with this specification, values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.  
1.5 The SI portions of the tables contained herein list permissible variations in dimensions and mass (see Note 1) in SI (metric) units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to SI tolerances is mandatory when the “M” specification is used.
Note 1: The term weight is used when inch-pound units are the standard. However, under SI the preferred term is  mass.  
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.7 This specification is expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers standards for high-strength, low-alloy, hot-rolled and cold-rolled steel sheets and strips cut in lengths or coils for structural and miscellaneous purposes. The material shall come in Types 2 and 4 steels having enhanced atmospheric corrosion resistance. The material shall follow specified carbon, manganese, and sulfur contents. Tension test shall be performed and material shall comply with tensile strength, yield strength, and elongation requirements. Edges and surface finish of the materials shall conform to specifications. Guidelines for retests are also given.
SCOPE
1.1 This specification covers high-strength, low-alloy, cold-rolled sheet and strip in cut lengths or coils, hot-rolled sheet and strip steel in cut lengths or coils with ordered thickness less than 0.230 in. [6.0 mm], and hot-rolled sheet coils (not cut lengths) with ordered thickness 0.230 in. [6.0 mm] and thicker, intended for use in structural and miscellaneous purposes, where savings in weight or added durability are important. These steels have enhanced atmospheric corrosion resistance and are supplied in three types or as commercial steel (CS). Type 2 contains 0.20 % minimum copper based on cast or heat analysis (0.18 % minimum Cu for product check). Type 4 and Type 5 contain additional alloying elements and provide a level of corrosion resistance substantially better than that of carbon steels with or without copper addition (Note 1). When properly exposed to the atmosphere, Type 4 and Type 5 steels can be used in the bare (unpainted) condition for many applications. CS is intended for applications that require enhanced atmospheric corrosion resistance which do not require a specified strength. CS shall contain the chemical requirements of Type 2, Type 4, or Type 5. CS as contained within this specification is not associated with the requirements of CS that are referenced in other Subcommittee A01.19 on Steel Sheet and Strip specifications.
Note 1: For methods of establishing the atmospheric corrosion resistance of low-alloy steels, see Guide G101.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 Welding—In general, the steels listed in this specification are weldable with commonly obtained welding electrodes. When the steel is to be welded, a suitable welding procedure based on its composition should be used, taking into account intended use and service temperatures.
Note 2: For a general discussion of the weldability of steel and carbon equivalents, consult Appendix X3 of A6/A6M.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Note 1: The changes in width limits with the publication of A635/A635M – 06a result in a change in tensile testing direction for material from 0.180 in. [4.5 mm] to 0.230 in. exclusive [6.0 mm exclusive] over 48 in. [1200 mm] wide, as that material is now covered by Specification A568/A568M – 06a. The purchaser is advised to discuss this change with the supplier.  
1.4 In case of any conflict in requirements, the requirements of the individual material specification shall prevail over those of this general specification.  
1.5 For the purposes of determining conformance with this and the appropriate product specifications referenced in 1.2, measured values, calculated values, and observed values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.  
1.5.1 Ordered values, identified in tables, specified such as over 30 through 48, or 30 exclusive to 48 inclusive, covers all ordered values specified as 30.1, 30.01, 30.001, etc., up to and including 48.000 etc., but does not cover ordered values specified as 30.000 etc. or less, nor does it cover ordered values specified as 48.1, 48.01, 48.001, etc., in accordance with the absolute method of Practice E29.  
1.6 Annex A1 lists permissible variations in dimensions and mass (see Note 2) in SI [metric] units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to Annex A1 is mandatory when the “M” specification is used.  
Note 2: The term weight is used when inch-pound units are the standard. However, under SI, the preferred term is mass.  
1.7 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.8 This specification and the applicable material specifications are expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.

ABSTRACT
This specification covers carbon steel flat wire in coils or cut lengths. The steel materials shall be produced from rimmed, capped, semi-killed, hot-rolled or cold-rolled steel. The steel specimens shall undergo cast or heat analysis and product analysis and shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, and copper. The desired edge shall be classified as follows: prepared edge of a specified contour produced when a very accurate width is required or when the finish of the edge suitable for electroplating is required, or both (Number 1 Edge); not applicable to flat wire products ( Number 2 Edge); approximately square edge produced by slitting (Number 3 Edge); rounded edge produced either by edge rolling or resulting from flat rolling of a round section (Number 4 Edge); square edge produced from slit-edge material on which the burr is eliminated by rolling or filling (Number 5 Edge); and square edge produced by edge rolling when the width tolerance and edge condition are not as exacting as for No. 1 Edge (Number 6 Edge). The dimensional tolerances shall conform to the required values of thickness, width and length. The steel materials shall conform to the required values of temper, Rockwell hardness and tensile strength.
SCOPE
1.1 This specification covers carbon steel flat wire in coils or cut lengths. Flat wire is classified as a cold-rolled section, rectangular in shape, 0.500 in. [12.7 mm] or less in width and under 0.250 in. [6.35 mm] in thickness.  
1.2 Low-carbon steel flat wire is produced from steel compositions with a maximum carbon content of 0.25 % by cast or heat analysis.  
1.3 Carbon spring steel flat wire is produced to a carbon range in which the specified or required maximum is over 0.25 % by cast or heat analysis.  
1.3.1 Two types of carbon spring steel flat wire are produced:
1.3.1.1 Untempered cold-rolled carbon spring steel flat wire, produced to several desirable combinations of properties and
1.3.1.2 Hardened and tempered carbon spring steel wire.  
1.4 Definite application flat wire is a product developed for a specific application and may be specified only by size and descriptive name.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers the standard for hot-rolled and cold-rolled alloy and structural alloy-steel sheet and strip. The material shall be furnished in several conditions: heat treatments such as hot-rolling and cold rolling; surface conditions; and edges, as specified herein, in coils or cut lengths. Heat analysis shall be performed on the material and shall conform to the required chemical compositions for carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, and vanadium. Materials in the annealed, normalized, or normalized-and-tempered condition shall be capable of meeting the longitudinal bend test requirements. Two tension tests and two hardness tests shall be made from coupons obtained from each heat (cast) and heat treatment lot.
SCOPE
1.1 This specification covers hot-rolled and cold-rolled alloy and structural alloy-steel sheet and strip. Alloy steel is furnished to chemical composition requirements and is intended primarily for general or miscellaneous use where bending and moderate forming is a requirement. Structural alloy steel is furnished to chemical composition requirements and to specific mechanical property requirements which may include tension tests, hardness tests, or other commonly accepted mechanical tests.  
1.2 If material of a higher degree of uniformity of internal soundness and freedom from surface imperfections is required, reference should be made to Specification A507.  
1.3 Alloy and structural alloy-steel sheet and strip are not produced to internal cleanliness requirements. Normally surface imperfections are not objectionable, and a good finish is not a prime requirement.  
1.4 The formability of structural alloy steel decreases with increasing yield strength or hardness. Therefore, product design in relation to the mechanical properties of the grade used must be considered.  
1.5 The material covered by this specification may be furnished in several conditions: heat treatments, surface conditions, and edges, as specified herein, in coils or cut lengths.  
1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers hot-rolled and cold-rolled drawing alloy steel sheets and strips for applications involving severe cold plastic deformation such as deep drawn or severely formed parts.

ABSTRACT
This specification covers the general requirements for hot-rolled steel strip in coils and cut lengths. It applies to carbon steel and high-strength, low-alloy steel furnished as hot-rolled. Hot-rolled material shall be furnished hot-rolled, not annealed, or pickled. The chemical composition shall be in accordance with the applicable product specification. Where the material is used for fabrication by welding, care must be exercised in the selection of chemical composition or mechanical properties to ensure compatibility with the welding process and its effect on altering the properties. A heat analysis shall be conducted to determine the percentage of elements specified or restricted by the applicable specification. The specimens shall be subjected to bend and tension tests.
SCOPE
1.1 This specification covers the general requirements for hot-rolled steel strip in coils and cut lengths. It applies to carbon steel and high-strength, low-alloy steel furnished as hot-rolled.  
1.2 This specification is not applicable to hot-rolled heavy-thickness carbon sheet and strip coils (Specification A1018/A1018M), cold-rolled carbon steel strip (Specification A109/A109M), high-strength, low-alloy cold-rolled steel (Specifications A606/A606M and A1008/A1008M) or cold-rolled high carbon steel (Specification A684/A684M).  
1.3 In case of any conflict in requirements, the requirements of the individual material specification shall prevail over those of this general specification.  
1.4 For the purposes of determining conformance with this and the appropriate product specification referenced under 2.1, values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.  
1.5 Annex A1 lists permissible variations in dimensions and mass (Note 1) in SI [metric] units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to Annex A1 is mandatory when the “M” specification is used.  
Note 1: The term “weight” is used when inch-pound units are the standard; however, under SI, the preferred term is “mass.”  
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

ABSTRACT
This specification covers requirements for as cold-reduced, steel sheet in coils intended for conversion into cold-rolled steel sheet on continuous annealing lines, and metallic-coated steel sheet on continuous hot-dip coating lines. As cold-reduced steel sheet in coils comes in a semi-finished form and is produced to thickness requirements expressed to 0.001 in. (0.01 mm). Due to the high degree of cold reduction, as cold-reduced steel sheet exhibits high tensile strength with very minimal ductility.
This specification prescribes the requirements for chemical composition; mechanical properties; dimensions and mass; flatness, width, and coil size; product finish and condition; and packaging and marking.
SCOPE

ABSTRACT
This specification deals with the hot-rolled, heavy thickness coils available for three designations: alloy steel, drawing steel, and structural alloy steel. Alloy steel is intended for general or miscellaneous use where bending and moderate forming is required. Drawing steel is used for severe cold plastic deformation such as deep drawn or severely formed parts. The material is available only in coils such as strip and sheet. As-rolled and annealed heat treatment shall be used for manufacturing the material. Drawing steel shall be furnished with a spheroidized annealed heat treatment unless otherwise specified. Heat analysis shall conform to the required grade specified for standard alloy steel, nonstandard alloy steel, and structural alloy steel. Grades shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, and vanadium. Mechanical tests for regular quality alloy steel and strip are not applicable; but for drawing steel and structural alloy steel, tension and hardness tests are required.
SCOPE
1.1 This specification covers hot-rolled, heavy thickness coils beyond the size limits of Specifications A506 and A507.  
1.2 The product is available in three designations: Alloy Steel, Drawing Steel, and Structural Alloy Steel.  
1.3 Alloy steel is furnished to chemical composition requirements and is intended primarily for general or miscellaneous use where bending and moderate forming is a requirement.  
1.4 Drawing steel is produced principally for applications involving severe cold plastic deformation such as deep drawn or severely formed parts.  
1.4.1 Drawing steel may be furnished in several conditions, heat treatments, surface finishes, and edges, as specified herein.  
1.5 Structural steel is furnished to chemical composition requirements and to specific mechanical property requirements which may include tension tests, hardness tests, or other commonly accepted mechanical tests.  
1.5.1 The formability of structural steel decreases with increasing yield strength or hardness. Therefore, product design in relation to the mechanical properties of the grade used must be considered.  
1.6 This material is available only in coils described as follows:

ABSTRACT
This specification covers cold-rolled, high-carbon strip. The strip shall be furnished cold rolled spheroidized annealed, soft annealed, intermediate hardness, or full hard, as specified. The heat or cast analysis shall conform to that specified requirement. Hardness test and bend test shall be made to conform to the requirements specified.
SCOPE
1.1 This specification covers cold-rolled, high-carbon strip in coils or cut lengths. Strip is classified as product that is 0.3000 in. [7.6 mm] or less in thickness and over 1/2 to 2315/16 in. [12.5 to 600 mm] in width, inclusive. Strip tolerance products may be available in widths wider than 2315/16 in. (600 mm) by agreement between purchaser and supplier; however, such products are technically classified as cold-rolled sheet. The maximum of the specified carbon range is over 0.25 to 1.35 %, inclusive. It is furnished in the following types as specified:  
1.1.1 Soft spheroidized annealed high-carbon steel is intended for applications requiring maximum cold forming. It is normally produced to give the lowest maximum Rockwell hardness for each grade.  
1.1.2 Soft annealed high-carbon steel is intended for applications requiring moderate cold forming. It is produced to a maximum Rockwell hardness.  
1.1.3 Intermediate hardness high-carbon steel is intended for applications where cold forming is slight or a stiff, springy product is needed, or both. It is produced to specified Rockwell hardness ranges, the maximum being higher than obtained for the annealed type.  
1.1.4 Full hard high-carbon steel is intended for flat applications. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gauge. Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both. The minimum hardness should be established between the consumer and the producer.  
1.2 This specification is applicable for orders in either inch-pound units or SI units.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 The tolerances in this specification are different than those in Specification A568/A568M and Specification A109/A109M.  
1.5 For the purpose of determining conformance with this specification, values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.  
1.6 This specification is expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units. The metric portions of the tables herein list permissible variations in dimensions and mass (see Note 1) in SI (metric) units. The values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values. Conformance to SI tolerances is mandatory when the “M” specification is used.
Note 1: The term weight is used when inch-pound units are the standard. However, under SI the preferred term is mass.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers the general requirements for carbon, structural, and high-strength, low alloy steel sheets in coils and cut lengths. The steel sheets shall be manufactured by hot-rolling, cold-rolling or temper rolling. Cold-rolled sheets shall undergo annealing after being cold reduced to thickness. Products shall undergo cast or heat analysis, product, check, or verification analysis, and sampling. Product analyses shall be performed wherein specimens shall conform to required chemical composition of carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, vanadium, columbium, niobium, titanium, aluminum, and nitrogen. Mechanical properties of the materials shall conform to the following properties: tensile strength, yield strength, and bending strength. Thickness, length, width and flatness tolerances and allowances for cold-rolled and hot-rolled sheets are indicated. Steel may be produced as ingot-cast or strand-cast.
SCOPE
1.1 This specification covers the general requirements for steel sheet in coils and cut lengths. It applies to the following specifications that describe carbon steel, structural steel, and high-strength, low-alloy steel (HSLA) furnished as hot-rolled sheet and cold-rolled sheet: Specifications A414/A414M, A424/A424M, A606/A606M, A659/A659M, A794/A794M, A1008/A1008M, A1011/A1011M, and A1039/A1039M.  
1.2 This specification is not applicable to hot-rolled heavy-thickness carbon sheet coils (Specification A635/A635M).  
1.3 In case of any conflict in requirements, the requirements of the individual material specification shall prevail over those of this general specification.  
1.4 For the purposes of determining conformance with this and the appropriate product specification referenced in 1.1, values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.  
1.5 Annex A1 lists permissible variations in dimensions and mass (see Note 1) in SI [metric] units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to Annex A1 is mandatory when the “M” specification is used.  
Note 1: The term weight is used when inch-pound units are the standard. However, under SI the preferred term is  mass.  
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.7 This specification and the applicable material specifications are expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.  
1.5 Tolerances are found in General Requirements Specifications A568/A568M and A635/A635M. The appropriate General Requirements specification is applied based on the thickness and width of the product ordered.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet. The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process. Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness requirements. Bend tests shall be conducted in accordance with requirements specified.
SCOPE
1.1 This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet, with specific temper, with specific edge or specific finish, and in sizes as follows:    
Width, in.  
Thickness, in.    
Over 1/2 to 2315/16  
0.300 and under    
Over 12.5 to 600 mm  
7.6 mm and under  
1.2 Cold-rolled strip is produced with a maximum specified carbon not exceeding 0.25 percent.  
1.3 Strip tolerance products may be available in widths wider than 2315/16 in. [600 mm] by agreement between purchaser and supplier. However, such products are technically classified as cold rolled sheet. The tolerances, finishes, tempers, edges, and available widths and thicknesses differentiate cold rolled strip from the product known as cold rolled sheet which is defined by Specification A568/A568M and from cold rolled high carbon strip which is defined by Specification A682/A682M.  
1.4 For the purpose of determining conformance with this specification, values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.  
1.5 The SI portions of the tables contained herein list permissible variations in dimensions and mass (see Note 1) in SI (metric) units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to SI tolerances is mandatory when the “M” specification is used.
Note 1: The term weight is used when inch-pound units are the standard. However, under SI the preferred term is  mass.  
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.7 This specification is expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers standards for high-strength, low-alloy, hot-rolled and cold-rolled steel sheets and strips cut in lengths or coils for structural and miscellaneous purposes. The material shall come in Types 2 and 4 steels having enhanced atmospheric corrosion resistance. The material shall follow specified carbon, manganese, and sulfur contents. Tension test shall be performed and material shall comply with tensile strength, yield strength, and elongation requirements. Edges and surface finish of the materials shall conform to specifications. Guidelines for retests are also given.
SCOPE
1.1 This specification covers high-strength, low-alloy, hot- and cold-rolled sheet and strip in cut lengths or coils, intended for use in structural and miscellaneous purposes, where savings in weight or added durability are important. These steels have enhanced atmospheric corrosion resistance and are supplied in three types: Type 2 contains 0.20 % minimum copper based on cast or heat analysis (0.18 % minimum Cu for product check). Type 4 and Type 5 contains additional alloying elements and provides a level of corrosion resistance substantially better than that of carbon steels with or without copper addition (Note 1). When properly exposed to the atmosphere, Type 4 and Type 5 steels can be used in the bare (unpainted) condition for many applications.  
Note 1: For methods of establishing the atmospheric corrosion resistance of low-alloy steels, see Guide G101.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 Welding—In general, the steels listed in this specification are weldable with commonly obtained welding electrodes. When the steel is to be welded, a suitable welding procedure based on its composition should be used, taking into account intended use and service temperatures.
Note 2: For a general discussion of the weldability of steel and carbon equivalents, consult Appendix X3 of A6/A6M.

1.2 The product is available in six designations: Commercial Steel, Drawing Steel, Structural Steel, High-Strength Low-Alloy Steel, High-Strength Low-Alloy Steel with Improved Formability, and Ultra-High Strength Steel.  
1.3 This material is available only in coils described as follows:    
Product  
Size Limits, Coils Only  
Width, in. [mm]  
Thickness, in. [mm]  
Strip  
Over 8 to 12, incl
[Over 200 to 300]  
0.230 to 1.000, incl
[From 6.0 through 25]  
Sheet  
Over 12
[Over 300]  
0.230 to 1.000, incl
[From 6.0 through 25]
Note 1: The changes in width limits with the publication of A635/A635M – 06a result in a change in tensile testing direction for material from 0.180 in. [4.5 mm] to 0.230 in. exclusive [6.0 mm exclusive] over 48 in. [1200 mm] wide as that material is now covered by Specification A568/A568M – 06a. The purchaser is advised to discuss this change with the supplier.  
1.4 Sheet and strip in coils of sizes noted in 1.3 are covered by this specification only with the following provisions:  
1.4.1 The material is to be fed directly from coils into a blanking press, drawing or forming operation, tube mill, rolling mill, or sheared or slit into blanks for subsequent drawing or forming.  
1.4.2 The material is not to be converted into steel plates for structural or pressure vessel use unless tested in complete accordance with the appropriate sections of Specifications A6/A6M (plates provided from coils) or A20/A20M (plates produced from coils). Plate converted from coils is no longer governed by this sheet steel specification and since this material is now a plate, the requirements of the appropriate plate specification shall apply, except in cases where there is a conflict between the requirements of the plate specification and this specification. In these cases, the more restrictive limits of either specification shall apply.  
1.4.3 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specification.  
1.4.4 Not all strength levels are available in all thicknesses. The user should consult the producer for appropriate size limitations.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

ABSTRACT
This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet. The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process. Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness requirements. Bend tests shall be conducted in accordance with requirements specified.
SCOPE
1.1 This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet, with specific temper, with specific edge or specific finish, and in sizes as follows:    
Width, in.  
Thickness, in.    
Over 1/2 to 2315/16  
0.300 and under    
Over 12.5 to 600 mm  
7.6 mm and under  
1.2 Cold-rolled strip is produced with a maximum specified carbon not exceeding 0.25 percent.  
1.3 Strip tolerance products may be available in widths wider than 2315/16 in. [600 mm] by agreement between purchaser and supplier. However, such products are technically classified as cold rolled sheet. The tolerances, finishes, tempers, edges, and available widths and thicknesses differentiate cold rolled strip from the product known as cold rolled sheet which is defined by Specification A568/A568M and from cold rolled high carbon strip which is defined by Specification A682/A682M.  
1.4 For the purpose of determining conformance with this specification, values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.  
1.5 The SI portions of the tables contained herein list permissible variations in dimensions and mass (see Note 1) in SI (metric) units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to SI tolerances is mandatory when the “M” specification is used.
Note 1: The term weight is used when inch-pound units are the standard. However, under SI the preferred term is  mass.  
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.7 This specification is expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.
