2、ntheses 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 specification2covers carbon steel shapes, plates,and bars of
3、structural quality for use in riveted, bolted, orwelded construction of bridges and buildings, and for generalstructural purposes.1.2 Supplementary requirements are provided for use whereadditional testing or additional restrictions are required by thepurchaser. Such requirements apply only when spe
4、cified in thepurchase order.1.3 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 forinformation on weldability.1.4 The values stated in either inch-pound units or SI unitsare to
5、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 is tobe used independently of the other, without combining valuesin any way.1.5 The text of this specification contains notes or f

17、 been cut to individual lengths from a coil. Theprocessor directly controls, or is responsible for, the operationsinvolved in the processing of a coil into a finished structuralproduct. Such operations include decoiling, leveling orstraightening, hot-forming or cold-forming (if applicable),cutting t
18、o length, testing, inspection, conditioning, heat treat-ment (if applicable), packaging, marking, loading for shipment,and certification.NOTE 1For structural products produced from coil and furnishedwithout heat treatment or with stress relieving only, two test results are tobe reported for each qua
