1.4568 Austenite Martensite Precipitation Hardening Stainless steel

Austenite Martensite Precipitation Hardening Stainless steel 1.4568

Stainless steel 1.4568 equal material : AISI631, SUS631, X7CrNi17-7, 17-7PH, S17700

1.4568 is a 18-8CrNi based development of austenite Martensite Precipitation Hardening Stainless steel, also known as the control phase stainless steel.1.4568 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.1.4568 corrosion resistance superior to that of general martensitic stainless steel.
