Material Description

Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. This 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).

Applications

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