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.

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.
