About Alloy
301 is an austenitic chromium-nickel stainless steel that is available in the annealed and cold worked conditions. In the annealed condition, 301 offers the highest level of stretch formability of any stainless steel and in the heavily cold worked condition offers the highest strength level of any 300 series stainless steel. 301 is non-magnetic in the annealed condition but becomes magnetic as a result of cold working.
301 is corrosion resistant in many environments, but the corrosion properties are less than that of 304/304L stainless steel. The susceptibility to carbide precipitation during welding restricts the use of 301 in some applications and 304L is used because of its lower carbon content for welded applications.
301 High Yield is an austenitic chromium-nickel stainless steel suitable for use in extra high strength and hardness applications. 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.
