Special Quality High-Tensile, Hard-Drawn Mechanical Spring Wire and Springs(Cancelled Jun 1998)
This SAE Recommended Practice covers the mechanical and chemical requirements of special quality high tensile, hard-drawn carbon-steel spring wire with restricted size tolerances. This material is used where such restricted dimensional requirements are necessary for the manufacture of highly stressed mechanical springs and wire forms. It is generally employed for applications subject to static loads or infrequent stress repetitions. This document also covers the processing requirements of springs and forms fabricated from this wire.
