1、Designation: A283/A283M 18Standard Specification forLow and Intermediate Tensile Strength Carbon Steel Plates1This standard is issued under the fixed designation A283/A283M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year
2、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. Scope*1.1 This specification2covers tw
3、o grades (C and D) ofcarbon steel plates of structural quality for general application.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 A6/A6M forinformation on weldability.1.3 The va
4、lues 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 may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two
5、systems may result in non-conformance with thestandard.1.4 For plate produced from coil and furnished without heattreatment or with stress relieving only, the additionalrequirements, including additional testing requirements and thereporting of additional test results, of Specification A6/A6Mapply.1

General Requirements for Delivery3.1 Plates furnished under this specification shall con-formto the requirements of the current edition of SpecificationA6/A6M, for the specific date ordered, unless a conflict exists,in wh
9、ich case this specification shall prevail.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,
10、the operations involved in the processingof 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
11、 furnished without heattreatment or with stress relieving only, two test results are to be reportedfor each qualifying coil.Additional requirements regarding plate producedfrom coil are described in Specification A6/A6M.4. Materials and Manufacture4.1 The steel shall be made by one or more of the fo
12、llowingprocesses: basic-oxygen or electric-furnace.4.2 The steel shall be killed.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.02 on Structural Steel for Bridges, Buildings, Rolling
