3、ent of Defense.1.Scope*1.1 This specification2covers alloy and stainless steel bolt-ing materials and bolting components for pressure vessels,valves,flanges,and fittings for high temperature or highpressure service,or other special purpose applications.SeeSpecification A962/A962M for the definition
4、of bolting.Barsand wire shall be hot-wrought and may be further processed bycenterless grinding or by cold drawing.Austenitic stainlesssteel may be carbide solution treated or carbide solution treatedand strain-hardened.When strain hardened austenitic stainlesssteel is ordered,the purchaser should t
5、ake special care toensure that Appendix X1 is thoroughly understood.1.2 Several grades are covered,including ferritic steels andaustenitic stainless steels designated B5,B8,and so forth.Selection will depend upon design,service conditions,me-chanical properties,and high temperature characteristics.1
6、.3 The following referenced general requirements are in-dispensable for application of this specification:SpecificationA962/A962M.NOTE1The committee formulating this specification has includedseveral steel types that have been rather extensively used for the presentpurpose.Other compositions will be
7、 considered for inclusion by thecommittee from time to time as the need becomes apparent.NOTE2For grades of alloy-steel bolting suitable for use at the lowerrange of high temperature applications,reference should be made toSpecification A354.NOTE3For grades of alloy-steel bolting suitable for use in
8、 lowtemperature applications,reference should be made to SpecificationA320/A320M.1.4 Nuts for use with bolting are covered in Section 13.1.5 Supplementary Requirements are provided for use at theoption of the purchaser.The supplementary requirements shallapply only when specified in the purchase ord
