Advances in the research of nitrogen containing stainless steels

Abstract

The current status of nitrogen containing stainless steels at home and abroad has been introduced. The function and existing forms of nitrogen in stainless steels, influence of nitrogen on mechanical properties and anti-corrosion properties as well as the application of the nitrogen containing stainless steels were discussed in this paper. It is clear that nitrogen will be a potential and important alloying element in stainless steels. And Argon Oxygen Decarbonization (AOD) refining can provide an advanced manufacture process for nitrogen containing stainless steels with ultra-low carbon and high cleaniness.
