ASTM A228/A228M-00

Standard Specification for Steel Wire, Music Spring Quality

SCOPE
1.1 This specification covers a high quality, round, cold-drawn steel music spring quality wire, uniform in mechanical properties, intended specially 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.
