Gall-Tough® Plus

UNS #S20162/S21800

Gall-Tough® Plus (Nitronic 60) is a high silicon, high manganese, nitrogen strengthened, austenitic stainless alloy which exhibits superior self-mated galling and metal-to-metal wear resistance. The alloy possesses higher strength and chloride corrosion resistance equal to or better than 316, along with equivalent high temperature oxidation resistance. Gall-Tough® Plus stainless may be considered for applications in which parts are in relative motion under load without lubricants.
