Standard Specification for Steel Wire, High-Carbon Spring, for Heat-Treated Components
ABSTRACT
This specification deals with the general requirements for round carbon spring steel wire coils intended for the manufacture of mechanical springs and wire forms that are heat treated after fabrication. Heat treatment processes include austenitizing, quenching and tempering. The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process and the wire shall be thermally treated, or thermally treated and drawn. Product analysis, wrap testing, and chemical analysis shall be performed and materials shall conform to the requirements for chemical composition, metallurgical structure and mechanical properties such as tensile strength. Packaging of the coils of wire shall be by agreement between the manufacturer and the purchaser wherein the agreement shall include coil dimensions and weights, while marking and bar coding for identification shall be by tag securely attached to each coil of wire.
SCOPE
1.1 This specification covers round carbon spring steel wire in coils intended for the manufacture of mechanical springs and wire forms that are heat treated (austenitized, quenched, and tempered) after fabrication.
1.2 The values stated in inch-pound units are to be regarded as the standard.
