Austenitic stainless steel refers to the stainless steel with chromium nickel as the main alloy element and has austenitic structure at room temperature. The stable austenitic structure is obtained when Cr, Ni and C are about 18%, 8%~10% and 0.1% respectively. Austenitic chromium-nickel stainless steel includes the well-knew 18CR-8Ni steel and the high Cr-Ni series steel developed by adding elements such as Mo, Cu, Si, Nb, Ti and so on. Austenitic stainless steel is nonmagnetic and has good mechanical properties (high toughness and malleability), easy to be machined, stamped and welded. High chromium content greatly improves the corrosion resistance of steel, because the surface is easy to form a very dense and hard chrome oxide protective film. In the oxidizing environment, it has good corrosion resistance, heat resistance and low temperature resistance, suitable for heavy load and no high requirements corrosion resistance equipment and components, and has a very wide range of uses especially in civil, light industry and other fields.

European standards: EN10217-7: 2021.
Super Austenitic stainless steel is a type of alloy content (MO, CR, Ni, N, etc.) significantly higher than that of ordinary austenitic stainless steel. It is one of the important directions for the development of high -quality special stainless steel. The typical of Super Austenitic stainless steel containing 6%molybdenum and 7%molybdenum.The synergy of CR, MO and N make Super Austenite stainless steel in acidic acid -containing has a very excellent anti -uniform corrosion performance. Under the conditions of seawater, gap, and low -speed scouring, it has good erosive resistance (Pren 56) and better resistant to resistance. Especially for sulfuric acid root ions, chloride ions and other acid root ions, it can be used in a very harsh working environment. In addition, Super austenitic Stainless Steel also has excellent comprehensive mechanical performance. Therefore, these steels are widely used in very harsh service environments such as flue gas treatment equipment, nuclear power industry, pharmaceutical engineering, pulp bleach, phosphate fertilizer and fertilizer industry, marine industry and waste treatment.
