6.4 mm diameter tensile specimens from center of 25.4 mm diameter bar annealed 1066°C 1 hour, water quenched, and ground.
Threshold Galling Stress 103 MPa (higher stress tests not performed). The avg. total volume loss on the wear test is 5 mm³ at 100 rpm.
Gall-Tough® stainless is a high silicon, high manganese, nitrogen strengthened, austenitic stainless alloy which possesses superior self-mated galling resistance and metal-to-metal wear resistance. The alloy possesses higher strength and high temperature oxidation resistance than Type 304 stainless with comparable corrosion resistance, depending on the environment.
