Type 201 Stainless Steel

Type 201 (UNS S20100) 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. Type 201 addresses the volatility of nickel prices while offering comparable corrosion resistance and formability to Type 301 and Type 304 and has become a viable lower cost alternative to these austenitic grades.


While Type 201 can substitute for Type 301 in many applications, it is less resistant to corrosion, particularly in chemical environments.
