A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last

3、revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers high-strength low-alloy struc-tural steel shapes, plates, and bars for welded, riveted, or boltedconstruction but intended primarily for use in welded bridge

4、sand buildings where savings in weight or added durability areimportant. The atmospheric corrosion resistance of this steel inmost environments is substantially better than that of carbonstructural steels with or without copper addition (see Note 1).When properly exposed to the atmosphere, this stee

5、l is suitablefor many applications in the bare (unpainted) condition. Thisspecification is limited to material up to 8 in. 200 mminclusive in thickness.NOTE 1For methods of estimating the atmospheric corrosion resis-tance of low-alloy steels, see Guide G101.1.2 When the steel is to be welded, a weld

See Appendix X3 of Specification A6/A6M forinformation 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 sho

The values stated in eachsystem are not exact equivalents; therefore, each system is tobe used independently of the other, without combining valuesin any way.1.4 The text of this specification contains notes, footnotes,or both, that provide explanatory material. Such notes andfootnot

Theprocessor directly controls, or is responsible for, the operationsinvolved in

12、the processing of a coil into a finished structuralproduct. Such operations include decoiling, leveling orstraightening, hot-forming or cold-forming (if applicable),cutting to length, testing, inspection, conditioning, heat treat-ment (if applicable), packaging, marking, loading for shipment,and cer
