17-4 PH washers 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 washers yield strength is up over 4 times greater. When compared to Duplex 2205 washers, the yield strength of 17-4 PH can be up to 2-½ times greater. 17-4 washers are available in 8 different aged (precipitation hardened) conditions offering a variety of mechanical properties (see below).
