An extremely strong precipitation hardened stainless steel
- Well suited for high strength applciaitons
- Up to 4x stronger thand 316 stainless steel
- Maintains its mechanical strength up to 600°F
- 17-4PH Chemistry & Specifications
17-4 PH bolts are made from a precipitation hardened stainless steel most known for its exceptional strength and its ability to maintain its mechanical properties to 600°F. Compared to 316 stainless steel, 17-4 PH bolts yield strength is up over 4 times greater. When compared to Duplex 2205 bolts, the yield strength of 17-4 PH can be up to 2-½ times greater.
17-4 bolts are available in 8 different aged (precipitation hardened) conditions offering a variety of mechanical properties (see below).
