3、use by agencies of the Department of Defense.1. Scope*1.1 This specification2covers alloy and stainless steel bolting for pressure vessels, valves, flanges, and fittings for hightemperature or high pressure service, or other special purpose applications. See Specification A962/A962M for the definiti
4、on ofbolting. Bars and wire shall be hot-wrought and may be further processed by centerless grinding or by cold drawing. Austeniticstainless steel may be carbide solution treated or carbide solution treated and strain-hardened. When strain hardened austenitic steelis ordered, the purchaser should ta
5、ke special care to ensure that Appendix X1 is thoroughly understood.1.2 Several grades are covered, including ferritic steels and austenitic stainless steels designated B5, B8, and so forth. Selectionwill depend upon design, service conditions, mechanical properties, and high temperature characteris
6、tics.1.3 The following referenced general requirements are indispensable for application of this specification: SpecificationA962/A962M.NOTE 1The committee formulating this specification has included fifteen steel types that have been rather extensively used for the present purpose.Other composition
7、s will be considered for inclusion by the committee from time to time as the need becomes apparent.NOTE 2For grades of alloy-steel bolting suitable for use at the lower range of high temperature applications, reference should be made toSpecification A354.NOTE 3For grades of alloy-steel bolting suita
8、ble for use in low temperature applications, reference should be made to Specification A320/A320M.1.4 Nuts for use with bolting are covered in Section 14.1.5 Supplementary Requirements are provided for use at the option of the purchaser. The supplementary requirements shallapply only when specified
9、in the purchase order or contract.1.6 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contractspecifies the applicable M specification designation (SI units), the inch-pound units shall apply.1.7 The values stated in either SI units or
10、inch-pound units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be usedindependently of the other. Combining values from the two systems may result in non-confo
