ng Stainless steel 17-7PH equal material : AISI631, SUS631, X7CrNi17-7, 1.4568, S17700
17-7PH is a 18-8CrNi based development of austenite Martensite Precipitation Hardening Stainless steel, also known as the control phase stainless steel. 17-7PH stainless steel after solid solution treatment of austenitic organization is unstable, there is toughness and processability, good after the adjustment, the austenite carbide precipitates phenological changes of components, through the martensitic transformation processing, most organizations into the toughness of low carbon tempering martensite, this state is the use of steel in the state, there is temperature and good mechanical properties.
