Abstract：The updated studies on the structures, progresses on the equilibrium phase diagrams of high nitrogen steels and their application in the designing of high nitrogen steels were introduced. The formulae of nitrogen solubility in different nitrogen bearing steels are summarized and the key points in high nitrogen steels manufacturing process were pointed out. The effects of nitrogen in austenite, ferrite and dual-phase stainless steels were discussed. Nitrogen can increase the toughness of steels without losing strength, while the corrosion resistance can be improved. The applications of some typical high nitrogen steel grades were illustrated.
