Common Trade Names: 17-7PH,SUS631,S17700,07Cr17Ni7Al,W.Nr.1.4568

 17-7PH is austenitic-martensitic precipitation hardening stainless steel developed on the basis of 18-8CrNi, also known as controlled phase change stainless steel.At the solution treating temperature, 1900°F, the metal is austenitic but undergoes transformation to a low-carbon martensitic structure during cooling to room temperature. This transformation is not complete until the temperature drops to 90°F. Subsequent heating to temperatures of 900-1150°F for one to four hours precipitation strengthens the alloy. This hardening treatment also tempers the martensitic structure, increasing ductility and toughness
