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.
