Type 301 High Yield is an austenitic chromium-nickel stainless steel suitable for use in extra high strength and hardness applications. Type 301 High Yield’s minimum yield strength of 270,000 psi provides the extra high strength required for applications such as constant force springs, variable force springs, snap bands, clips, fasteners and washers. 301 High Yield is sold to ASTM A666 and AMS 5519 chemical properties only.
Chemical Composition (wt%) limits as specified in ASTM A240 and ASME SA240*
