Material Description
17-4PH (Type 630) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. This martensitic stainless steel maintains high strength up to approximately 600°F (316°C) and can achieve yield strengths up to 1100-1300 MPa through optimized heat treatment.
Key Features
- High strength and hardness maintained to 300°C
- Excellent mechanical properties through precipitation hardening
- Good corrosion resistance comparable to Alloy 304
- Available in various diameters from 8mm to 450mm
- Multiple finishing options: black bar or bright bar
- Custom cutting services available
