Alloy 50 is a durable austenitic stainless steel used for anti-galling applications with greater corrosion resistance than 304 or 316 stainless steel with nearly twice the yield strength. It has excellent mechanical properties at low and high temperature ranges. Nickel Systems stocks threaded rod/studs and nuts in Alloy 50 ranging from 1/2”-13 to 3/4”-10 in both finished and heavy pattern certified to ASTM A194 Grade 8r. Most designs of a gall resistant joint require only one component to be gall resistant.
