Historical (view previous versions of standard)
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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers a high quality, 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 (metric) units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
