ASTM-A227 › Standard Specification for Steel Wire, Cold-Drawn for Mechanical Springs
The following bibliographic material is provided to assist you with your purchasing decision:
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.
Scope
1.1 This specification covers two classes of round cold-drawn steel spring wire having properties and quality for the manufacture of mechanical springs, rings, and wire forms that are not subject to high stress or requiring high fatigue properties.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
