Abstract: With the development of the times, the traditional high manganese steel is difficult to meet today's needs in terms of mechanical properties, hardness and even wear resistance and corrosion resistance. Improving the mechanical properties and corrosion resistance of high manganese steel through nitrogen alloying to extend the service life of steel, and the preparation of nitrogen-containing high manganese steel with excellent performance and stability is a trend of today's development.The influence of nitrogen on the alloying of high manganese steel, the influence of the smelting process,casting process and heat treatment on nitrogen-containing high manganese steel were described in this article.Finally, the future development direction of high manganese steel was discussed and summarized.

Key words: nitrogen, high-manganese steel, alloying, smelting process, casting process, metal heat treatment
