Nitronic 50

UNS S20910, XM19

Nitronic 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 Nitronic 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.
