Standard Specification for Steel Wire, Cold-Drawn for Mechanical Springs

Abstract

This specification covers two classes of round cold-drawn steel spring wire having properties and quality for the manufacture of mechanical springs that are not subject to high stress or requiring high fatigue properties and wire forms. The steel specimens shall either be ingot cast or strand cast. Cast or heat and product analysis shall be performed wherein steel materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, and silicon. Specimens shall also undergo tension and wrap tests and shall conform to the requirements of tensile properties.
