Material Description

17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and moderate corrosion resistance. High strength is maintained to approximately 600°F (316°C).

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. Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved.

Applications

Offshore (foils, helicopter deck platforms)
Food industry equipment
Pulp and paper industry
Aerospace (turbine blades)
Mechanical components
Nuclear waste casks
