Material Description
17-4PH (Type 630) is a chromium-copper precipitation hardening martensitic stainless steel that provides high strength and moderate corrosion resistance. It maintains high strength up to approximately 600°F (316°C).
General Properties
Alloy 17-4 PH combines high strength, hardness (up to 572°F/300°C), and corrosion resistance. Mechanical properties can be optimized through heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi). Not recommended for use above 572°F (300°C) or at very low temperatures.
