Type 201 (UNS S20100)
Description
Type 201 is an austenitic chromium-nickel-manganese stainless steel that was developed in the 1950's due to worldwide nickel shortages. In the Type 201 composition, manganese and nitrogen are partially substituted for nickel. T201 addresses the volatility of nickel prices while offering comparable corrosion resistance and formability to T301 and T304 and has become a viable lower cost alternative to these austenitic grades. Type 201 can be used in many applications because of its wide range of mechanical properties in the annealed and cold worked condition. Type 201 is non-magnetic in the annealed condition but becomes magnetic as a result of cold working.
