Material Description
17-4PH (Type 630) is a precipitation hardening martensitic stainless steel with chromium-copper composition, offering high strength and moderate corrosion resistance. Mechanical properties can be optimized through heat treatment, achieving yield strength up to 1100-1300 MPa.
Applications
- Offshore equipment (foils, helicopter deck platforms)
- Food processing industry
- Pulp and paper industry
- Aerospace components (turbine blades)
- Mechanical components
- Nuclear waste casks

Physical Properties
| Property | Value |
|---|---|
| Density | 7750 kg/m³ |
| Thermal Conductivity (100°C) | 18.4 W/m·K |
| Specific Heat (0-100°C) | 460 J/kg·K |
| Electrical Resistivity | 800 nΩ·m |
Heat Treatment
Solution treatment at 1040°C for 0.5 hours followed by air cooling. Age hardening at various temperatures achieves desired mechanical properties with typical shrinkage of 0.10% for H1150 condition and 0.05% for H900 condition.
Machining & Welding
Can be machined in solution-treated condition with rates similar to grade 304 stainless steel. Welding can be performed using all conventional methods without pre-heating requirements.
