330 Stainless Steel is an austenitic nickel-iron-chromium alloy developed to provide excellent resistance to carburizing and oxidizing atmospheres at elevated temperatures. It remains highly resistant to both chloride stress corrosion cracking and embrittlement from the precipitation of sigma phase. The high nickel and chromium content provides excellent resistance to both oxidation and carburization. The alloy performs well under cyclic conditions of heating and cooling and in alternate carburizing and oxidizing atmospheres.
