AMS 5902

301 is an austenitic stainless steel capable of attaining high strengths and ductility by cold working.  It is not hardenable by heat treatment.  Type 301 is non-magnetic in the annealed condition and becomes increasingly magnetic with cold working.  It is preferable over types 302 and 304 in the tempered condition because the higher elongations (which are attainable at a given strength level) facilitate fabrication
