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.
