ASTM A228 / A228M
Abstract ASTM a228 pdf
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.
