Abstract
This specification covers a group of common requirements that shall apply to carbon, alloy, and stainless steel fasteners or fastener materials, or both. These materials are intended for use at any temperature from cryogenic to the creep range. Requirements for the melting process and quality control procedures for ingot cast and strand cast products are detailed. Bars and fasteners shall be produced in accordance with the product specification. The chemical composition, as to heat and product analyses, shall conform to the limits of the product specification. Bars, fasteners, bolting materials, and specimen machined from fasteners shall meet the mechanical requirements which shall be determined by the following tests: (1) proof load test by mandrel/tension or compression methods, (2) cone proof load test, (3) impact test, and (4) hardness test. Assembly for the proof load and cone proof tests are illustrated. The depth of decarburization shall be determined by metallographic etching and if needed, microhardness testing.
Scope
1.1 This specification covers a group of common requirements that shall apply to carbon, alloy, stainless steel, and nickel alloy bolting under any of the following ASTM Specifications (or under any other ASTM Specifications that invoke this specification or portions thereof):
