3、ment of Defense.1. Scope*1.1 This specification2covers five grades of bolting with twelve classes of yield strength ranging from 50 to 120 ksi 345 to827 MPa for use in high-temperature service such as fasteners for pressure vessel and valve flanges. See SpecificationA962/A962M for the definition of

The material requires special processing and is not intended for general purposeapplications.1.2 The following referenced general requirements are indispensable for application of this specification: SpecificationA962/A962M.1.3 Supplementary Requirements are provided for use at the option o
5、f the purchaser. The Supplementary Requirements shallonly apply when specified individually by the purchaser in the purchase order or contract.1.4 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contractspecifies the applicable “M” spec
