Shanghai Metal Corporation is a leading Nitronic 60 Wire manufacturer and supplier.
Nitronic 60 (Alloy 218, UNS S21800) is known for its excellent galling resistance, even at elevated temperatures and low temperature impact resistance. The additions of 4% silicon and 8% manganese inhibit wear, galling and fretting. It is commonly used for various fasteners and pins that require strength and resistance to galling. It maintains decent strength up to temperature of 1800F and has oxidation resistance similar to that of 309 stainless steel. The general corrosion resistance is between that of 304 and 316 stainless steel and the yield strength is twice that of 304 and 316.
