Designation A20/A20M − 15Standard Specification forGeneral Requirements for Steel Plates for Pressure Vessels1This standard is issued under the fixed designation A20/A20M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1.

United States11.4 Appendix X3 provides information on the variability ofCharpy-V-Notch impact test properties in plates for pressurevessels.1.5 Appendix X4 provides information on cold bending ofplates, including suggested minimum inside radii for coldbending.1.6 These materials are intended to be suitable for fusionwelding. When the steel is to be welded, it is presupposed thata welding procedure suitable for the grade of steel and intendeduse or service will be utilized.1.7 In case of any conflict in requirements, the requirementsof the applicable product specification prevail over those of thisgeneral requirements specification.1.8 Additional requirements that are specified in the pur-chase order and accepted by the supplier are permitted,provided that such requirements do not negate any of therequirements of this general requirements specification or theapplicable product specification.1.9 For purposes of determining conformance with thisgeneral requirements specification and the applicable productspecification, values are to be rounded to the nearest unit in theright-hand place of figures used in expressing the limitingvalues in accordance with the rounding method of PracticeE29.1.10 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.11 This general requirements specification and the appli-cable product specification are expressed in both inch-poundunits and SI units; unless the order specifies the applicable “M”specification designation SI units, the plates are to befurnished to inch-pound units.2.

Terminology3.1 Definitions of Terms Specific to This Standard3.1.1 coilhot-rolled steel in coil form for processing intofinished plates.3.1.2 exclusivewhen used in relation to ranges, as forranges of thicknesses in the tables of permissible variations indimensions, the term is intended to exclude only the greatervalue of the range. Thus, a range from 60 to 72 in. [1500 to1800 mm] exclusive includes 60 in. [1500 mm], but does notinclude 72 in. [1800 mm].3.1.3 heat treatment termssee 3.1.8, and TerminologyA941.3.1.4 hot forminga forming operation producing perma-nent deformation, performed after the plate has been heated tothe temperature required to produce grain refinement.3.1.5 manufacturerthe organization that directly controlsthe conversion of steel ingots or slabs, by hot rolling, intoplate-as-rolled or into coil; and for plates produced fromplate-as-rolled, the organization that directly controls, or isresponsible for, one or more of the operations involved infinishing the plates. Such finishing operations include leveling,cutting to length, testing, inspection, conditioning, heat treat-ment if applicable, packaging, marking, loading for shipment,and certification.3.1.5.1 DiscussionThe finishing operations need not bedone by the organization that did the hot rolling of the plate.For plates produced from coil, see also 3.1.1.3.1.6 plate identifierthe alpha, numeric, or alphanumericdesignation used to identify the plate.3.1.7 platesflat hot-rolled steel, ordered to thickness orweight and typically to width and length, commonly availableby size as followsWidth, in.

[mm]Over 8 [200] over 0.229 [6.0 mm and over]Over 48 [1200] over 0.179 [4.6 mm and over]3.1.7.1 DiscussionSteel plates are available in variousthickness, width, and length combinations dependent uponequipment and processing capabilities of various manufactur-ers and processors. Historic limitations of a plate based upondimensions thickness, width, and length do not take intoaccount current production and processing capabilities. Toqualify any plate to a particular product specification requiresthat all appropriate and necessary tests be performed and thatthe results meet the limits prescribed in that product specifi-cation. If the necessary tests required by a product specificationcan not be conducted, the plate can not be qualified to thatspecification. This general requirements specification containspermitted variations for the commonly available sizes. Permit-ted variations for other sizes are subject to agreement betweenthe purchaser and the manufacturer or processor, whichever isapplicable.3.1.8 precipitation heat treatmenta subcritical tempera-ture thermal treatment performed to cause precipitation ofsubmicroscopic constitue
