1、Designation: A 285/A 285M 03 (Reapproved 2007)Standard Specification forPressure Vessel Plates, Carbon Steel, Low- andIntermediate-Tensile Strength1This standard is issued under the fixed designationA 285/A 285M; the number immediately following the designation indicates the yearof original adoption
2、 or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Sco
3、pe*1.1 This specification2covers carbon steel plates of low-and intermediate-tensile strengths which may be made bykilled, semi-killed, capped, or rimmed steel practices at theproducers option. These plates are intended for fusion-weldedpressure vessels.1.2 Plates under this specification are availa
4、ble in threegrades having different strength levels as follows:Grade Tensile Strength, ksi MPaA 4565 310450B 5070 345485C 5575 3805151.3 The maximum thickness of plates under this specifica-tion, for reasons of internal soundness, is limited to a maximumthickness of 2 in. 50 mm for all grades.NOTE 1
5、For killed carbon steels only refer to the following ASTMspecifications:3A 299/A 299M Pressure Vessel Plates, Carbon Steel, Manganese-Silicon.A 515/A 515M Pressure Vessel Plates, Carbon Steel, forIntermediate- and Higher-Temperature ServiceA 516/A 516M Pressure Vessel Plates, Carbon Steel, for Moder
6、ate-and Lower-Temperature Service.1.4 For plates produced from coil and furnished withoutheat treatment or with stress relieving only, the additionalrequirements, including additional testing requirements and thereporting of additional test results, of Specification A 20/A 20M apply.1.5 The values s
7、tated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from thetwo systems ma

General Requirements and Ordering Information3.1 Plates supplied to this product specification shall con-form to Spec
9、ification A 20/A 20M, which outlines the testingand retesting methods and procedures, permissible variationsin dimensions and mass, quality and repair of defects, marking,loading, etc.3.2 Specification A 20/A 20M also establishes the rules forordering information that should be complied with whenpur
10、chasing plates to this specification.3.3 In addition to the basic requirements of this specifica-tion, certain supplementary requirements are available whereadditional control, testing, or examination is required to meetend use requirements.3.4 The purchaser is referred to the listed supplementaryre
11、quirements in this specification and to the detailed require-ments in Specification A 20/A 20M.3.5 Coils are excluded from qualification to this specifica-tion until they are processed into finished plate. Plates pro-duced from coil means plates that have been cut to individuallengths from coil. The
12、 processor directly controls, or isresponsible for, the operations involved in the processing ofcoils into finished plates. Such operations include decoiling,leveling, cutting to length, testing, inspection, conditioning,heat treatment (if applicable), packaging, marking, loading forshipment, and ce
13、rtification.NOTE 2For plates produced from coil and furnished without heattreatment or with stress relieving only, three test results are reported foreach qualifying coil. Additional requirements regarding plate producedfrom coil are described in Specification A 20/A 20M.1This specification is under
14、 the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.11 on Steel Plates for Boilers and Pressure Vessels.Current edition approved Nov. 1, 2007.
