Super Austenitic Stainless Steel Pipe
When cr-ni austenitic stainless steel pitting resistance equivalent value (PREN = 3.3 [Mo] [Cr] + + 16 [N]) & ge; 40%, can be called super austenitic stainless steel. Super austenitic stainless steel is mainly to solve the problem of severe corrosion of the containing Cl - under the condition of the original high molybdenum (> 4%) cr-ni austenitic stainless steel properties, such as resistance to pitting corrosion, crevice corrosion and the deficiency of the developed poor thermal stability of the tissue.
