17-4 PH Fasteners

17-4 PH fasteners 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 fastener's yield strength is up over 4 times greater. When compared to Duplex 2205 fasteners, the yield strength of 17-4 PH can be up to 2-½ times greater. RAYCHIN 17-4 fasteners are available in 8 different aged (precipitation hardened) conditions offering a variety of mechanical properties (see below). In addition, we also offer 17-4PH fasteners per ASTM F593 Grade 630 which ensures specific tensile and yield strengths.
