An extremely strong precipitation hardened stainless steel
- Well suited for high strength applications
- Up to 4x stronger than 316 stainless steel
- Maintains its mechanical strength up to 600°F
- 17-4PH Chemistry & Specifications
17-4 PH blind flanges 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 blind flanges yield strength is up over 4 times greater. When compared to Duplex 2205 blind flanges, the yield strength of 17-4 PH can be up to 2-½ times greater.
17-4 blind flanges are available in 8 different aged (precipitation hardened) conditions offering a variety of mechanical properties (see below).
17-4PH Specifications: UNS S17400, AISI 630, ASTM A564-630, AMS 5604 Sheet, Strip and Plate ASTM A 693 Plate
