Material Description
17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and moderate corrosion resistance. High strength is maintained to approximately 600°F (316°C).
General 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, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).
Applications
- Offshore (foils, helicopter deck platforms)
- Food industry
- Pulp and paper industry
- Aerospace (turbine blades)
- Mechanical components
- Nuclear waste casks
Standards
- ASTM A693 grade 630 (AMS 5604B) UNS S17400
- EURONORM 1.4542 X5CrNiCuNb 16-4
- AFNOR Z5 CNU 17-4PH
- DIN 1.4542
Corrosion Resistance
Alloy 17-4 PH withstands corrosive attacks better than standard hardenable stainless steels and is comparable to Alloy 304 in most media. For stress corrosion cracking risks, higher aging temperatures (over 1022°F/550°C) must be selected.

| Electrical Resistivity (nΩ.m) | 800 |
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. Typical shrinkage is 0.10% for condition H1150 and 0.05% for condition H900.
Applications
- Engine components
- High strength and boat propeller shafts
- Plastic moulding dies
- Valves and gears
