Scope of standard 1.1 This general requirements specification2 covers a group of common requirements that, unless otherwise specified in the applicable product specification, apply to rolled steel plates for pressure vessels covered by each of the following product specifications issued by ASTM: Title of Specification ASTM DesignationA Pressure Vessel Plates, Alloy Steel, Nickel A203/A203M Pressure Vessel Plates, Alloy Steel, Molybdenum A204/A204M Pressure Vessel Plates, Alloy Steel, Manganese- Vanadium-Nickel A225/A225M Stainless Chromium Steel-Clad Plate A263 Stainless Chromium-Nickel Steel-Clad Plate A264 Nickel and Nickel-Base Alloy-Clad Steel Plate A265 Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength A285/A285M Pressure Vessel Plates, Carbon Steel, Manganese-Silicon A299/A299M Pressure Vessel Plates, Alloy Steel, Manganese- Molybdenum and Manganese-Molybdenum-Nickel A302/A302M Pressure Vessel Plates, Alloy Steel, Double- Normalized and Tempered 9 % Nickel A353/A353M Pressure Vessel Plates, Alloy Steel, Chromium- Molybdenum A387/A387M Pressure Vessel Plates, Carbon Steel, High Strength Manganese A455/A455M Pressure Vessel Plates, Carbon Steel, for Intermediate- and Higher-Temperature Service A515/A515M Pressure Vessel Plates, Carbon Steel, Moderate- and Lower-Temperature Service A516/A516M Pressure Vessel Plates, Alloy Steel, High-Strength, Quenched and Tempered A517/A517M Pressure Vessel Plates, Alloy Steel, Quenched and Tempered, Manganese-Molybdenum and Manganese- Molybdenum-Nickel A533/A533M Title of Specification ASTM DesignationA Pressure Vessel Plates, Heat-Treated, Carbon- Manganese-Silicon Steel A537/A537M Pressure Vessel Plates, Alloy Steel, Quenched-and- Tempered, Chromium-Molybdenum, and Chromium- Molybdenum-Vanadium A542/A542M Pressure Vessel Plates, Alloy Steel, Quenched and Tempered Nickel-Chromium-Molybdenum A543/A543M Pressure Vessel Plates, Alloy Steel, Quenched and Tempered 7, 8, and 9 % Nickel A553/A553M Pressure Vessel Plates, Carbon Steel, Manganese- Titanium for Glass or Diffused Metallic Coatings A562/A562M Pressure Vessel Plates, Carbon Steel, High Strength, for Moderate and Lower Temperature Service A612/A612M Pressure Vessel Plates, 5 % and 51/2 % Nickel Alloy Steels, Specially Heat Treated A645/A645M Pressure Vessel Plates, Carbon-Manganese-Silicon Steel, for Moderate and Lower Temperature Service A662/A662M Pressure Vessel Plates, Carbon-Manganese-Silicon Steel, Quenched and Tempered, for Welded Pressure Vessels A724/A724M Pressure Vessel Plates, Low-Carbon Age-Hardening Nickel-Copper-Chromium-Molybdenum-Columbium (Niobium) Alloy Steel A736/A736M Pressure Vessel Plates, High-Strength Low-Alloy Steel A737/A737M Pressure Vessel Plates, Heat-Treated, Carbon- Manganese-Silicon Steel, for Moderate and Lower Temperature Service A738/A738M Pressure Vessel Plates, Alloy Steel, Chromium- Molybdenum-Vanadium A832/A832M Steel Plates for Pressure Vessels, Produced by Thermo-Mechanical Control Process (TMCP) A841/A841M Steel Plates, 9 % Nickel Alloy, for Pressure Vessels, Produced by the Direct-Quenching Process A844/A844M Pressure Vessel Plates, Alloy Steel, Chromium- Molybdenum-Tungsten A1017/A1017M(A) These designations refer to the latest issue of the respective specification which appears in the Annual Book of ASTM Standards, Vol 01.04. 1.1.1 This general requirements specification also covers a group of supplementary requirements that are applicable to several of the above product specifications as indicated therein. Such requirements are provided for use if additional testing or additional restrictions are required by the purchaser, and apply only if specified individually in the purchase order. 1.2 Appendix X1 provides information on coil as a source of plates for pressure vessels. 1.3 Appendix X2 provides information on the variability of tensile properties in plates for pressure vessels. 1.4 Appendix X3 provides information on the variability of Charpy-V-Notch impact test properties in plates for pressure vessels. 1.5 Appendix X4 provides information on cold bending of plates, including suggested minimum inside radii for cold bending. 1.6 These materials are intended to be suitable for fusion welding. 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. 1.7 In case of any conflict in requirements, the requirements of the applicable product specification prevail over those of this general requirements specification. 1.8 Additional requirements that are specified in the purchase order and accepted by the supplier are permitted, provided that such requirements do not negate any of the requirements of this general requirements specification or the applicable product specification. 1.9 For purposes of determining conformance with this general requirements specification and the applicable product specification, values are to 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. 1.10 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. 1.11 This general requirements specification and the applicable product specification are expressed in both inch-pound units and SI units; unless the order specifies the applicable “M” specification designation (SI units), the plates are to be furnished to inch-pound units. 1.12 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.
