Characteristics and application of super austenitic stainless steel

characteristic

Among all stainless steels, super austenitic stainless steel has the most stringent technical requirements and is the most difficult steel. Because super austenitic stainless steel contains high content of nickel and molybdenum, as well as copper and nitrogen, it is not easy to melt, segregate and crack. Therefore, super austenitic stainless steel can become a technical caliber for steel mills. Like other commonly used Cr Ni austenite, super austenitic stainless steel has good cold and hot workability.

application
