Type 301Si is an austenitic stainless steel capable of attaining very high strengths while maintaining ductility through cold working. It is not hardenable by heat treatment. Type 301Si is non magnetic in the annealed condition and becomes increasingly magnetic when cold worked. 301Si has an increased silicon content over standard 301 and is typically used for "super" high strength applications. The extra silicon allows for even better ductility at high tensile strengths than standard 301. Both are produced to ASTM A666.
