301 Stainless Steel Sheet & Coil - AMS 5901


Type 301 is an austenitic stainless steel with a nominal composition of 17 percent chromium and 7 percent nickel, which provides good strength and ductility when cold worked. It also has excellent corrosion resistance properties. 301 is well suited to welding and forming and drawing.  This high strength grade of steel is available in several conditions or tempers.  United Performance Metals also supplies 301 in its Full Hard, 1/2 Hard and 1/4 Hard conditions.

Mechanical Properties and Yield Strength of 301

Type 301 is used in the annealed and cold rolled conditions. In the work-hardened condition, Type 301 develops higher tensile strength than the other stable austenitic grades. Minimum properties for plate, sheet and strip per ASTM A240 and A666 follow.
