Thefunctionandexisting forms of nitrogeninthestainless steels, influenceof nitrogenonmechan-i cal properties andresis-t corrosionproperties aswellastheapplicationof nitrogencontainedstainless cast steels are involvedinthis paper. It isclear that nitrogenwillbeanimportant andpotential alloy element in stainlesssteels.
