Farmers Copper Ltd. maintains an inventory of UNS S21800 stainless steel in round bar. 218 stainless is an anti-galling and wear resistance austenitic stainless steel. The additions of silicon and manganese have given this alloy a matrix to inhibit wear, galling and fretting even in the annealed condition. It also performs well in metal-to-metal wear in normally inert atmospheres. The general corrosion resistance of S21800 falls between 304 and 316 stainless, and maintains good strength up to 1800 degree F and has oxidation resistance similar to 309 stainless.
