Martensitic & Precipitation hardened stainless steel


Martensitic & Precipitation hardened stainless steel

Precipitation Hardening (PH) stainless steels are classified as martensitic or semi-austenitic. They develop their high strength and hardness through a variety of heat treatments resulting in a very high strength-to-weight ratio. Semi-austenitic grades are 17-4ph, 17-7PH and PH 15-7 Mo, 15-5PH.
