ASTM A231/A231M-96(2002)
(Specification)Standard Specification for Chromium-Vanadium Alloy Steel Spring Wire
Standard Specification for Chromium-Vanadium Alloy Steel Spring Wire
SCOPE
1.1 This specification covers round chromium-vanadium alloy steel spring wire having properties and quality intended for the manufacture of springs used at moderately elevated temperatures. This wire shall be either in the annealed and cold-drawn or oil-tempered condition as specified by the purchaser.
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 independent of the other.
