This can be attributed to the enhanced levels of chromium, molybdenum and nitrogen found in these materials. Failure analysis:Sulfur stress corrosion cracking of Dec 01, 2020 · The S30432 austenitic stainless steel is the most susceptible to SCC. The main corrosive elements of sulfur, which is from coal burning. Two of the three conditions are already in place, the key factor for the stress corrosion crack is stress. Stresses that contribute to SCC can arise during manufacturing/ fabrication or in service.

As with the other types of stainless steels, the austenitic stainless steels are corrosion and oxidation resistant due to the presence of chromium that forms a self What is a super austenitic stainless steel? - Langley AlloysA super austenitic stainless steel is considered to be one with a Pitting Resistance Equivalent Number (PREN) greater than 40. This is usually attributed to alloys with high additions of molybdenum, typically 6% or greater. Austenitic stainless steels are the most commonly used family of stainless steels in general engineering applications.
Super austenitic stainless steel When the pitting resistance equivalent value of chromium-nickel austenitic stainless steel (PREN= [Cr]+3.3 [Mo]+16 [N]) 40%, it can be called super austenitic stainless steel. Super austenitic stainless steel is mainly used to solve the problems of pitting corrosion and crevice corrosion resistance of the original high molybdenum (>4%) chromium-nickel austenitic stainless steel
