Easy-to-Machine High-Strength 17-4 PH Stainless Steel

- Yield Strength: 118,000 psi
- Hardness: Rockwell C35 (Hard)
- Heat Treatment: Annealed (Softened)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C47
- Specifications Met: ASTM A564
Also known as Project 70+ and 630 stainless steel, this material machines faster with less wear on cutting tools than standard 17-4 PH stainless steel. It has a higher chromium content than 15-5 PH stainless steel, so it offers better corrosion resistance. Maximum temperature for corrosion resistance is not rated.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
