(Specification)Standard Specification for Steel Wire, Music Spring Quality
Standard Specification for Steel Wire, Music Spring Quality
ABSTRACT
This specification covers high quality, round, cold-drawn steel music spring quality wire for the manufacture of springs subject to high stresses or requiring good fatigue properties. The steel shall either be ingot cast or strand cast. Heat and product analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, manganese, phosphorus, sulfur, and silicon. Steel specimens shall also undergo tension test, wrap test, and torsion tests. Final products shall be marked by a tag.
SCOPE
1.1 This specification covers two types of round, cold-drawn steel music spring quality wire, uniform in mechanical properties, intended especially for the manufacture of springs subject to high stresses or requiring good 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.
