Standard Specification for Steel Wire, Chromium-Silicon Alloy

Abstract

This specification covers round chromium-silicon alloy steel spring wire having properties and quality intended for the manufacture of springs resistant to set when used at moderately elevated temperatures. This product is not meant to be used for high cycle fatigue applications. Either ingot or strand cast steel may be made by any commercially accepted steel making process. The steel shall conform on heat and product analysis to the chemical composition requirements prescribed for carbon, manganese, phosphorus, sulfur, silicon, and chromium. Annealed and cold drawn or oil-tempered wires shall conform to the specified mechanical properties including tensile strength. Requirements for tension and wrap tests as well as metallurgical requirements for etched surface testing and decarburization are detailed.

Scope

1.1 This specification covers round chromium-silicon alloy steel spring wire having properties and quality intended for the manufacture of springs resistant to set when used at moderately elevated temperatures. This product is not meant to be used for high cycle fatique applications (see Specification A 877/A 877M). This wire shall be provided either in the annealed and cold-drawn or oil-tempered condition as specified by the purchaser.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other.
