UNS S21800

N-60 stainless steel is known for its excellent wear resistance, even at high temperatures. The addition of 4% silicon and 8% manganese inhibits wear, abrasion, and jitter. It is commonly used for the strength and wear resistance of fasteners and pins that are required for a variety of purposes. It retains good strength at temperatures of 1800°F and has oxidation resistance similar to that of 309 stainless steel. The general corrosion resistance is between 304 and 316 stainless steel.
