Material Description
17-4PH Stainless Steel (Type 630) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. This alloy maintains high strength up to approximately 600°F (316°C).
General Properties
Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance. Mechanical properties can be optimized with heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).
