The influence of nitrogen on the structure and properties of austenite is studied. It is shown that change of 18Mn–18Cr steel austenite lattice parameter in the range of 0.51–0.713~wt.\% N has a monothonic character. Increase of nitrogen content leads to a possibility of $ϵ$–Cr$_{2}$N creation. Decrease of nitrogen content can lead to the creation of a $σ$–phase. Cold working of 18Mn–18Cr steel is accompanied by microtwinning as well as by simple dislocation mechanism with strip formation in one or several directions.
