1、Designation: A 283/A 283M 03 (Reapproved 2007)Standard Specification forLow and Intermediate Tensile Strength Carbon Steel Plates1This standard is issued under the fixed designation A 283/A 283M; the number immediately following the designation indicates the yearof original adoption or, in the case
2、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. Scope*1.1 This speci
3、fication2covers four grades (A, B, C, and D)of carbon steel plates of structural quality for general applica-tion.1.2 When the steel is to be welded, a welding proceduresuitable for the grade of steel and intended use or service is tobe utilized. See Appendix X3 of Specification A 6/A 6M forinformat
4、ion on weldability.1.3 The values stated 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 exactly equivalents; therefore, each system is tobe used independently of the other, w
5、ithout combining valuesin any way.1.4 For plate produced from coil and furnished without heattreatment or with stress relieving only, the additional require-ments, including additional testing requirements and the re-porting of additional test results, of Specification A 6/A 6Mapply.1.5 This specifi
6、cation contains notes or footnotes, or both,that provide explanatory material. Such notes and footnotes,excluding those in tables and figures, do not contain anymandatory requirements.2.

General Requirements for Delivery3.1 Plates furnished under this specification shall con-formto the requirements of the current edition of SpecificationA 6/A 6M, for the specific date ordered, unless a conflictexists, in which case this specification shall p
8、revail.3.2 Coils are excluded from qualification to this specifica-tion until they are processed into finished plates. Platesproduced from coil means plates that have been cut toindividual lengths from a coil. The processor directly controls,or is responsible for, the operations involved in the proc
9、essingof a coil into finished plates. Such operations include decoiling,leveling, cutting to length, testing, inspection, conditioning,heat treatment (if applicable), packaging, marking, loading forshipment, and certification.NOTE 1For plates produced from coil and furnished without heattreatment or
10、 with stress relieving only, two test results are to be reportedfor each qualifying coil.Additional requirements regarding plate producedfrom coil are described in Specification A 6/A 6M.4.
