Material Description
17-4PH Stainless Steel
17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. This alloy maintains high strength up to approximately 600°F (316°C).
Alloy 17-4 PH 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 equipment (foils, helicopter deck platforms)
- Food processing industry
- Pulp and paper manufacturing
- Aerospace components (turbine blades)
- Mechanical components
- Nuclear waste casks
- Engine components
- Boat propeller shafts
- Plastic molding dies
- Valves and gears
