Product Details

When the pitting corrosion resistance equivalent value of Cr-Ni austenitic stainless steel is greater than or equal to 40%, it can be called super austenitic stainless steel. Super austenitic stainless steel is mainly developed to solve the defects of pitting corrosion resistance, crevice corrosion resistance and poor thermal stability of the original high molybdenum (more than 4%) Cr-Ni austenitic stainless steel under severe corrosion conditions containing chloride ions.
