Material 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 with very high yield strength up to 1100-1300 MPa (160-190 ksi).

Applications

Offshore applications (foils, helicopter deck platforms)
Food industry equipment
Pulp and paper industry
Aerospace components (turbine blades)
Mechanical components
Nuclear waste casks
Engine components
High strength boat propeller shafts
Plastic moulding dies
Valves and gears

Heat Treatment

Solution treatment (Condition A): Heated at 1040°C for 0.5 h, then air-cooled to 30°C. Small sections can be oil quenched.

Hardening: Age-hardened at low temperatures to achieve required mechanical properties. During the process, superficial discoloration occurs followed by shrinkage.
