ABSTRACT
This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction intended primarily for use as structural members where savings in weight (mass) or added durability are important. Steel specimens shall be semi-killed or killed. Heat analysis shall be performed wherein steel specimens shall conform to required chemical compositions of carbon, manganese, phosphorus, sulfur, and copper. Atmospheric corrosion resistance shall be estimated for steel specimens. Specimens shall also undergo tension tests and shall conform to specified values of tensile strength, yield point, and elongation.
SCOPE
1.1 This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction intended primarily for use as structural members where savings in weight [mass] or added durability are important. The atmospheric corrosion resistance of the steel in most environments is substantially better than that of carbon structural steels with or without copper addition. When properly exposed to the atmosphere, this steel can be used bare (unpainted) for many applications (see Note 1). This specification is limited to material up to 4 in. [100 mm], inclusive, in thickness.  
Note 1: For methods of estimating the atmospheric corrosion resistance of low-alloy steels, see Guide G101.  
1.2 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.  
1.3 The values stated in either inch-pound units or SI units are to be regarded 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 must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.  
1.4 For structural products produced from coil and furnished without heat treatment or with stress relieving only, the additional requirements, including additional testing requirements and the reporting of additional test results, of Specification A6/A6M apply.  
1.5 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 three types and four strength grades of high strength low-alloy, hot rolled structural steel plate with improved formability. These steels are normally furnished in the as-rolled condition.

Chemical composition requirements shall be dependent upon thickness, grade, and intended applications. Tension tests shall be executed to evaluate conformance of specimens with specified mechanical properties requirements.
SCOPE
1.1 This specification covers three types and five strength grades of high-strength low-alloy, hot-rolled structural steel plate for use in truck frames, brackets, crane booms, rail cars, and similar applications. Steels that conform to this specification offer improved formability. These steels are normally furnished in the as-rolled condition. The type and strength grade furnished is as agreed upon between the manufacturer and the purchaser. The types and strength grades are shown in the tables.  
1.2 The maximum thickness of plates shall be as follows:    
Grade  
Plate Thickness, max,
in. [mm]  
50  
2 [50]  
60  
11/2 [40]  
70  
1 [25]  
80  
1 [25]  
100  
1/2 [13]  
1.3 The values stated in either inch-pound units or SI units are to be regarded 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 must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.  
1.4 For plates produced from coil and furnished without heat treatment or with stress relieving only, the additional requirements, including additional testing requirements and the reporting of additional test results, of Specification A6/A6M apply.  
1.5 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 normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. This material is suited for low ambient temperatures where the desired notch toughness is better than that expected in as-rolled materials of comparable strength level. The material shall have fine austenitic grain size and shall be normalized by heat treatment. Its chemical composition shall be determined by heat analysis. Tension tests shall also be done.
SCOPE
1.1 This specification covers normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction.  
1.2 This material is particularly suited for service at low ambient temperatures of −50 °F [−45 °C] and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired.  
1.3 Four grades, designated Grades A, C, D, and E are covered by this specification. Grade A provides a minimum yield point of 42 ksi [290 MPa]. Grades C and D provide a minimum yield point of 50 ksi [345 MPa] in thicknesses up to 2.50 in. [65 mm], inclusive and 46 ksi [315 MPa] in thicknesses over 2.50 in. [65 mm]. Grade E provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. [100 mm].  
1.4 Current practice normally limits plates furnished under this specification to maximum thickness of 4 in. [100 mm] for Grades A, C, and D, and to a maximum thickness of 6 in. [150 mm] for Grade E. However, the maximum thickness of the plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.  
1.5 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.  
1.6 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. 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 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 carbon and high-strength steel shapes of structural quality manufactured by the electric resistance forge-welding process from coils. The specimens shall be established by the steel supplier, shape manufacturer, and shape purchaser of the materials. Specimens shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur and silicon. Specimens shall undergo tension tests, peel tests and tee tension tests and shall conform to the required values of tensile strength, yield point, and elongation.
SCOPE
1.1 This specification covers carbon and high-strength steel shapes of structural quality manufactured by the electric-resistance forge-welding process from coils.  
1.2 The size range covered is described in nominal dimensions for columns, beams, and tees.    
Size Range, in. (mm)  
Web thickness  
0.060 to 0.500 [1.5 to 12.7]  
Flange thickness  
0.060 to 0.500 [1.5 to 12.7]  
Overall depth  
2.00 to 24.00 [50 to 600]  
Flange width  
0.50 to 12.00 [12.7 to 300]  
1.3 These shapes are intended for two classes of application:  
1.3.1 Class 1—General structural use where static loading predominates.  
1.3.2 Class 2—Structural use where fatigue loading occurs and is a principal design consideration.  
Note 1: Caution—Because of the absence of smooth, integral, large radius fillets at the junctions of the webs and the flanges (see Fig. 1), fatigue limits of resistance forge-welded shapes in torsion, lateral loading, and flexure are usually lower than those for hot-rolled shapes of similar size and material. Users should consult shape manufacturers for recommended values of fatigue limits for each specific use, material, and size in cases where dynamic loading is a principal design consideration.

1.4 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.  
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.  
1.6 The following safety hazards caveat pertains only to the test methods portion, Section 10, of this specification: 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.  
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 deals with the procedures and acceptance standards for straight beam, pulse echo, ultrasonic examination of rolled structural shapes. The section surfaces shall be sufficiently clean and smooth to maintain a back reflection from the opposite side of the flanges, legs and webs. Ultrasonic testing shall be made on the major surface of each flange and one major web surface. Evaluation of indications may require inspection from an opposite surface. Two levels of acceptance standards are included. Level II is intended for normal applications where freedom from gross internal discontinuities is desired, particularly in connection regions. Level I is intended for critical applications such as welded chord members used in tension loading.
SCOPE
1.1 This specification covers the procedure and acceptance standards for straight beam, pulse echo, ultrasonic examination of rolled structural shapes having a minimum section thickness of 1/2 in. [12.5 mm]. It was developed to ensure delivery of steel structural shapes free of gross internal discontinuities such as pipe, ruptures, or laminations and is to be used whenever the inquiry, contract, order, or specification states that the shapes are to be ultrasonically examined. Two levels of acceptance standards are included. Level II is intended for normal applications where freedom from gross internal discontinuities is desired, particularly in connection regions. Level I is intended for critical applications such as welded chord members used in tension loading, where internal discontinuities could be detrimental. Level II is normally applicable unless otherwise specified in contract documents or the purchase order. Supplementary requirements for alternative scanning coverages are provided.  
1.2 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets.

SCOPE
1.1 This specification covers rolled steel structural shapes for use in building framing or bridges, or for general structural purposes.  
1.2 Supplementary requirements are provided for use where additional testing or additional restrictions are required by the purchaser. Such requirements apply only when specified in the purchase order.  
1.3 When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.  
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 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.  
1.5 The text of this specification contains notes or footnotes, or both, that provide explanatory material; such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements.  
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 high-strength low-alloy structural steel plates that were produced by the thermo-mechanical controlled process (TMCP). This method consists of rolling reductions and cooling rate controls, which result in mechanical properties in the finished plate that are equivalent to those attained using conventional rolling and heat treatment processes.
SCOPE
1.1 This specification covers steel plates produced by the thermo-mechanical controlled process (TMCP). Five grades are defined by the yield strength: 50 [345], 60 [415], 65 [450], 70 [485], and 80 [550]. The plates are intended primarily for use in welded steel structures.  
1.2 The TMCP method consists of rolling reductions and cooling rate controls that result in mechanical properties in the finished plate that are equivalent to those attained using conventional rolling and heat treatment processes, which entail reheating after rolling. A description of the TMCP method is given in Appendix X1.  
1.3 The maximum thicknesses available in the grades covered by this specification are shown in Table 1.  
1.4 Due to the special combination of mechanical and thermal treatment inducing lower rolling temperatures than for conventional hot rolling the plates cannot be formed at elevated temperatures without sustaining significant losses in strength and toughness. The plates may be formed and post-weld heat-treated at temperatures not exceeding 1050°F [560°C]. Higher temperatures may be possible if proven that minimum mechanical characteristics are retained after tests with specimens in the post-weld heat treatment (PWHT) condition. For flame straightening higher temperatures can be used in accordance with the steel manufacturer’s recommendations.  
1.5 If the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.  
1.6 Supplementary requirements are available but shall apply only if specified in the purchase order.  
1.7 Units—This specification is expressed in both inch-pound units and SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply. 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 is to be used independently of the other. Combining values from the two systems may result in nonconformances with the standard.  
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.

This specification deals with the standard structural quality of high-strength low-alloy nickel, copper, phosphorus steel H-piles and sheet piling for use in the construction of dock walls, bulkheads, excavations, and like applications in marine environments. The steel shall be semi-killed or killed and shall be exposed to the washing action of rain and the drying action of wind or sun, or both to determine its atmospheric corrosion resistance. Material specimens shall undergo product analysis, heat analysis, and tension testing and shall conform to the required chemical composition, tolerance, tensile strength, yield point, and elongation specifications.
SCOPE
1.1 This specification covers high-strength low-alloy nickel, copper, phosphorus steel H-piles and sheet piling of structural quality for use in the construction of dock walls, sea walls, bulkheads, excavations, and like applications in marine environments.  
1.2 The atmospheric corrosion resistance of this steel is substantially better than that of ordinary carbon steels with or without copper addition (see Note 1). The steel has also shown to have substantially greater resistance to seawater “Splash Zone” corrosion than ordinary carbon steel (Specifications A36/A36M and A328/A328M) where exposed to the washing action of rain and the drying action of the wind or sun, or both. Where the steel is not boldly exposed, the usual provisions for the protection of ordinary carbon steel should be considered.  
Note 1: For methods of estimating atmospheric corrosion resistance of low-alloy steels, see Guide G101.  
1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.  
1.4 The values stated in either inch-pound units or SI units are to be regarded 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 must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.  
1.5 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 test method deals with the standard sampling procedure for impact testing of structural steel. Covered are the procedures for longitudinal Charpy V-notch testing, which contain two testing frequencies. The two frequencies for testing (H and P), frequency (H) heat testing, and frequency (P) piece testing, are discussed and presented in details.
SCOPE
1.1 This specification covers the procedure for Charpy V-notch testing of structural steel and contains two frequencies of testing. The impact properties of steel can vary within the same heat and piece, be it as-rolled, control-rolled, or heat treated. The purchaser should, therefore, be aware that testing of one plate, bar, or shape does not provide assurance all plates, bars, or shapes of the same heat as processed will be identical in toughness with the product tested. Normalizing or quenching and tempering the product will reduce the degree of variation.  
1.2 This specification is intended to supplement specifications for structural steel when so specified.  
1.3 This specification does not necessarily apply to all product specifications; therefore, the manufacturer or processor should be consulted for energy absorption levels and minimum testing temperatures that can be expected or supplied.  
1.4 Two frequencies of testing (P and H) are prescribed.  
1.5 The values stated in either inch-pound units or SI units are to be regarded 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 must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.  
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.

1.6.7 Finish 7—Painted, one prime coat and one finish coat.  
1.6.8 The plates are usually specified to have Finish 1.  
1.7 Supplementary requirements are provided for additional requirements that may be specified on the order.  
1.8 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.  
1.9 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.  
1.10 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.
