Stainless Steel OD 16 18MM S21800 Nitronic 60 (High strength) Round bar

Nitronic 60 Stainless Steel Bar

UNS S21800

Nitronic 60 is truly an all purpose metal. A fully austenitic alloy originally designed as a wear alloy, considered to have the best galling resistance over the entire range of stainless steels. Other characteristics include good high temperature properties around 1799° F, crevice corrosion and chloride pitting resistance (both greater than Stainless Steel 316) , as well as, oxidation resistance comparable to Stainless Steel 309 and far better than Stainless Steels 304 and 316.

21800 is composed of between 16% to 18% chromium, 8% to 9% nickel, 7% manganese, 3.5% to 4.5% silicon, with the balance being iron. Also found in 21800 are trace amounts of carbon, sulfur, phosphorus and nitrogen. It can be formed using common forming techniques, and preheating is not required in the welding process. Common welding methods such as gas metal arc, gas tungsten arc and submerged arc can be used to weld this grade. Hardening 21800 calls for the alloy to be cold worked. It is the ideal material if your application requires a high temperature and wear resistant alloy with increased strength attained through cold worked practices.
