ASTM A533/A533M-24(Specification)

Standard Specification for Pressure Vessel Plates, Alloy Steel, Quenched and Tempered, Manganese-Molybdenum and Manganese-Molybdenum-Nickel

ABSTRACT
This specification covers manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates for use in welded pressure vessels. The steel materials shall be killed and shall conform to the required values of fine austenitic grain and shall also be heat treated. The steel specimens shall undergo heat analysis and product analysis and shall conform to the chemical requirements for carbon, manganese, phosphorus, sulfur, silicon, molybdenum, and nickel. Tension tests shall be performed wherein the steel specimens shall conform to the required values of tensile strength, yield strength, and elongation.
SCOPE
1.1 This specification2 covers one type of manganese-molybdenum and four types of manganese-molybdenum-nickel alloy steel plates for use in the quenched and tempered condition for the construction of welded pressure vessels.
1.2 Material under this specification is available in five types, designated “A,” “B,” “C,” “D,” and “E.” The material is also available in three classes having the following strength levels.
Class
Tensile Strength,
ksi [MPa]
1
80 to 100 [550 to 690]
2
90 to 115 [620 to 795]
3
100 to 125 [690 to 860]
1.3 The maximum thickness of Class 1 and Class 2 plates is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice normally limits the maximum thickness to 12 in. [300 mm] for Types A through D and to 7 in. [180 mm] for Type E.
1.4 The maximum thickness of Class 3 plates is 21/2 in. [65 mm] for Types A through D and 2 in. [50 mm] for Type E.
1.5 The minimum nominal thickness of plates of all classes is 0.25 in. [6.5 mm].
1.6 These alloy steel plates in the as-rolled condition are sensitive to cracking during transit and handling, particularly in thicknesses over 1 in. [25 mm]. They should be shipped in the as-rolled conditions only by mutual agreement of manufacturer and the purchaser.
1.7 Plates covered by this specification are often used in the beltline region of nuclear reactor vessels where the material properties may be affected by high levels of radiation. Appendix X1 provides some information pertinent to this usage.
1.8 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 must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.9 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.

Materials shall be manufactured to a killed fine austenitic grain size, by vacuum degas melting process. Heat treatment shall be conducted, according to class, by: normalizing and precipitation hardening (Grade A, Class 1); liquid quenching and precipitation hardening (Grade A, Class 2); or double liquid-quenching, tempering, double austenitizing, and precipitation hardening (Grade B). Heat and product analyses shall be used to evaluate the conformance of forgings to required chemical compositions. Tensile, notch toughness, and Charpy impact requirements shall be examined, for which one of four sampling methods may be employed. One tension test and one impact test (for three samples) shall be made for each forging. Dimensions and finishes of the forgings shall conform to that specified by the purchaser. Repair welding shall also be performed only if permitted by the purchaser.
SCOPE
1.1 This specification covers requirements for low-carbon age-hardening nickel-copper-chromium-molybdenum-columbium alloy steel forgings for pressure vessel components.

Materials shall be manufactured by steel melting processes, rough machining, and final heat treatment, which shall consist of normalizing, reaustenitization, liquid quenching, and tempering. Conformance of the forging specimens to chemical composition requirements shall be analyzed by heat and product analyses. Proper sampling methods for mechanical properties testing shall be done by any of four possible ways, as judged appropriate. Steel specimens shall also undergo straight-beam and angle-beam ultrasonic examination, and magnetic particle examination procedures to evaluate nondestructive examination requirements. Repair welding of the forgings shall not be permitted.

Standard Specification for Steel Plates, 9 % Nickel Alloy, for Pressure Vessels, Produced by the Direct-Quenching Process

ABSTRACT
This specification covers 9% nickel-alloy steel plates produced by the direct-quenching process. The plates are intended primarily for use in welded pressure vessels. The steel shall be killed and shall conform to the fine austenitic grain size requirement specified. The steel shall conform to the chemical requirements specified. Tension test and impact test shall be made to conform to the requirements specified.
SCOPE
1.1 This specification covers 9 % nickel-alloy steel plates produced by the direct-quenching process. The plates are intended primarily for use in welded pressure vessels.
1.2 The direct-quenching process consists of quenching the plates directly after rolling, without permitting the plates to cool below the critical temperature prior to initiation of the quenching operation, and subsequently tempering the plates (see Appendix X1). (Note: The direct-quenching process differs from the “conventional” process in which the plates are permitted to cool to a temperature significantly below the critical temperature, usually to ambient temperature, prior to reheating to a temperature above the upper critical temperature, then quenching, and subsequently tempering.)
1.3 If the plates are subjected to warm forming, the temperature shall not exceed 950°F [510°C].
1.4 The maximum nominal thickness of plates furnished under this specification shall not exceed 2 in. [50 mm].
1.5 This material is susceptible to magnetization. Use of magnets in handling after heat treatment should be avoided if residual magnetism would be detrimental to subsequent fabrication or service.
1.6 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. 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.
1.7 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.
