Possible environments for application of high nitrogen nickel free stainless steel: A Review

HNNFSS (high nitrogen nickel free austenitic stainless steels) are gaining attention due to superior combination of mechanical properties and corrosion resistance. 200 series of austenitic stainless steel are now being explored for different applications due to their affordability. This paper describes the various applications of high nitrogen nickel free austenitic stainless described in the literature and summarizes studies carried out under various environments. The available literature on different stainless steels with similar properties shows that HNNFSS has potential areas for application and research.
