J271_199406 SPECIAL QUALITY HIGH-TENSILE, HARD-DRAWN MECHANICAL SPRING WIRE AND SPRINGS

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 for springs and forms fabricated from this wire.
