3、ted in November 2017.2NOTE13.1.5 was editorially corrected in November 2018.1.Scope*1.1 This specification2covers the chemical and mechanicalrequirements of quenched and tempered alloy steel bolts,studs,and other externally threaded fasteners 4 in.and under indiameter for application at normal atmos
4、pheric temperatures,where high strength is required and for limited application atelevated temperature(Note 1).Any alloy steel capable ofmeeting the mechanical and chemical properties set forth inthis specification may be used.NOTE1For bolts,studs,or other externally threaded fasteners,to beused at
5、elevated temperatures,refer to Specification A193/A193M.1.2 Two strength levels are covered,designated Grades BCand BD.Selection will depend upon design and the stressesand service for which the product is to be used.NOTE2Quenched and tempered alloy steel bolts for structural steeljoints up through
6、112in.in diameter are covered in SpecificationF3125/F3125M.For fastener diameter sizes above 112in.,Grade BC maybe considered for structural steel bolting where tensile strength above 120ksi is necessary and Grade BD may be considered for structural steelbolting where tensile strength above 150 ksi
7、is necessary.In this event,additional requirements of Specification F3125/F3125M,such as headsize,lubricant,and magnetic particle inspection,should be carefullyconsidered.1.3 Nuts are covered in Specification A563.Unless other-wise specified,the grade and style of nut for each grade offastener shall
