Material Description

17-4PH (Type 630) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. It maintains high strength up to approximately 600°F (316°C).

General Properties

Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with copper and niobium additions. It 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).

Applications

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