Product Code:SAE AMS5112
Title:Carbon Steel, Wire, Spring Quality Music Wire 0.70 - 1.00C Cold Drawn
Issuing Committee:Ams E Carbon And Low Alloy Steels Committee
Scope:This specification covers a carbon steel in the form of wire supplied as coils, spools, or cut lengths. This wire has been used typically for springs subject to high stress or requiring good fatigue properties up to 200 °F (93 °C), but usage is not limited to such applications.
