Scope	1.1 This  specification covers precipitation hardening bolting (UNS N07718) for high  temperature service. See Specification for  the definition of “bolting.”    1.2 The  following referenced general requirements are indispensable for application  of this specification: Specification .    1.3  Supplementary requirements are provided for use at the option of the  purchaser. The supplementary requirements only apply when specified  individually in the purchase order or contract.    1.4 This  specification is expressed in both inch-pound and in SI units. However,  unless the purchase order or contract specifies the applicable M designation  (SI units), the 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.

Abstract	This specification covers a  precipitation hardening bolting material (UNS N07718) for high temperature service.  The alloy shall be multiple melted using consumable electrode practice in the  remelt cycle or shall be induction melted under vacuum. Requirements for  solution treatment, precipitation heat treatment, straightening, and thread  forming by rolling are detailed. Remelt ingots shall conform to the chemical  composition requirements (as to chemical and product analyses) prescribed for  the following elements: carbon, manganese, silicon, phosphorus, sulfur,  chromium, cobalt, molybdenum, columbium, titanium, aluminum, boron, iron,  copper, and nickel. Tensile, hardness, and stress rupture tests shall be  performed and test specimen shall meet the requirements specified for tensile  strength, yield strength, elongation, Brinell hardness, and stress rupture.  The method of determining the minimum full size breaking strength for headed  fastener is given. Metallography shall be taken for microstructure and  macrostructure properties including grain size and flow lines.
