301 High Yield Stainless Steel Strip 270 KSI Min Tensile

301 High Yield, ASTM A-666, UNS 30100, UNS 30116, is issued for special applications requiring extra high strength and hardness. This extra high strength material has a minimum tensile strength of 270,000 PSI. Gibbs Interwire provides 301 High Yield Strip in gauges from 0.0019" to 0.032" precision slit to widths from 0.024". Type 301 High Yield is sold to AMS5519 - Chemical properties only. Gibbs Interwire also carries 301 High Yield with Added Silicon for additional strength with improved ductility. 301 High Silicon has a silicon range of up to 1.3 as compared to the 1.0 range of standard High Yield.

Typical uses for 301 High Yield and 301 High Silicon include: Springs, Constant Force Springs, Clips, Clamps, Fasteners, Zippers and many precision stamped parts.
