3、s of the U.S.Department of Defense.1.Scope*1.1 This specification covers five grades of high-strengthlow-alloy structural steel shapes,plates,sheet piling,and bars.Grades 42 290,50 345,and 55 380 are intended forriveted,bolted,or welded structures.Grades 60 415 and 65450 are intended for riveted or
4、bolted construction of bridges,or for riveted,bolted,or welded construction in other applica-tions.1.2 For applications,such as welded bridge construction,where notch toughness is important,notch toughness require-ments are to be negotiated between the purchaser and theproducer.1.3 Specification A58
