High-Carbon Spring Steel Wire, Heat-Treated Components, ASTM International

This standard outlines the general requirements for round carbon spring steel wire coils, intended for manufacturing mechanical springs and wire forms that undergo heat treatment post-fabrication. Heat treatment processes include austenitizing, quenching, and tempering. The steel must be produced via open-hearth, basic-oxygen, or electric-furnace methods, with the wire being thermally treated or thermally treated and drawn. Product analysis, wrap testing, and chemical analysis must be conducted, ensuring materials meet requirements for chemical composition, metallurgical structure, and mechanical properties like tensile strength. Coil packaging is agreed upon by the manufacturer and purchaser, including coil dimensions and weights, with each coil tagged securely for identification.

• Wire Specifications: Round carbon spring steel wire in coils for heat-treated mechanical springs and wire forms
• Standard Units: Inch-pound units are the standard
• International Standard Development: Adheres to WTO TBT Committee's standardization principles
