Standard Specification for Alloy-Steel Bolting for Special Applications

ABSTRACT
This specification covers a group of common requirements that shall apply to steel flanges, forged fittings, valves, and parts for piping applications under any of the following individual product specifications. This specification covers regular and special-quality alloy steel bolting materials which may be used for nuclear and other special applications. Bolting materials as used in this specification cover rolled or forged bars, rotary pierced or extruded seamless tubes, bored bars, or forged hollows from forged or rolled bar segments to be manufactured into bolts, studs, washers, and nuts. The steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, vanadium. Material which is ordered in the liquid-quenched and tempered condition shall be uniformly reheated from a temperature below the cooling transformation range to the proper austenitizing temperature. It shall be quenched in a liquid medium under substantially uniform conditions and then uniformly reheated for tempering. Tensile test, hardness, and impact test shall be measured to conform to the required mechanical properties.
SCOPE
1.1 This specification covers regular and special-quality alloy steel bolting that may be used for nuclear and other special applications. See Specification  for the definition of bolting.
1.2 The following referenced common requirements are indispensable for application of this specification: Specification .
1.3 Supplementary requirements of an optional nature are provided for use at the option of the purchaser. These supplementary requirements only 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 contract specifies the applicable “M” specification designation (SI units), inch-pound units shall apply.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
