The optimal composition that ensures the necessary service characteristics of high strength austenitic nonmagnetic nitrogen stainless steels must contain, at least 18% Mn, 18% Cr, and 0,6% N. Chromium significantly affects corrosion cracking, relaxation, and erosion resistance. For more complex alloys containing nickel, molybdenum, and niobum, chromium has a considerable effect on plasticity bending, which is caused by ability of the alloy to resist forge-rolling (rigid cold stretching) that is used for the achievement of a high yield limit. The technology of nitration under pressure in the process of electro slag remelting allows one to regulate the content of nitrogen which is much greater than the solubility of nitrogen in steels under ordinary conditions. Application of special recrystallizing (mechanical and thermal) treatment and strain strengthening of blanks by cold working suppresses the formation of coarse-grained structure and ensures fine grains of eight to none number.
