1、Designation: A283/A283M 03 (Reapproved 2007) A283/A283M 12Standard 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

2、 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 Department of Defense.1. Scope*1.1 T

3、his specification2 covers four grades (A, B, C, two grades (C and D) of carbon steel plates of structural quality for generalapplication.1.2 When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to beutilized. See Appendix X3 of Specificat

The values stated in each system are not exactly equivalents; therefore, each system is to be usedinde

5、pendently of the other, without combining values in any way.1.4 For plate produced from coil and furnished without heat treatment or with stress relieving only, the additional requirements,including additional testing requirements and the reporting of additional test results, of Specification A6/A6M

General Requirements for Delivery3.1 Plates furnished under this specification shall con-form to the requirements of the current edition of Specification A6/A6M,for the specific date ordered, unless a conflict exists, in which case t

8、his specification shall prevail.3.2 Coils are excluded from qualification to this specification until they are processed into finished plates. Plates produced fromcoil means plates that have been cut to individual lengths from a coil. The processor directly controls, or is responsible for, theoperat

9、ions involved in the processing of a coil into finished plates. Such operations include decoiling, leveling, cutting to length,testing, inspection, conditioning, heat treatment (if applicable), packaging, marking, loading for shipment, and certification.NOTE 1For plates produced from coil and furnis

10、hed without heat treatment or with stress relieving only, two test results are to be reported for eachqualifying coil. Additional requirements regarding plate produced from coil are described in Specification A6/A6M.4. Process4.1 The steel shall be made by one or more of the following processes: ope
