ASTM B1011/B1011M-22 PDF

Scope: 1.1 This specification covers cold-drawn cobalt alloy spring wire intended especially for the manufacture of springs. 1.1.1 This specification requires capability properties after age hardening test samples of the cold worked spring wire to ensure final mechanical properties are satisfied. The spring is typically age hardened after fabrication to increase its strength. However, mechanical properties cannot be obtained from finished springs. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3 Unless the order specifies an “M” designation, the material shall be furnished to inch-pound units. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
