Abstrakt: 1.A structural diagram was constructed for 25% Cr steel that allows one to determine the minimum concentrations of nickel and nitrogen guaranteeing a stable austenitic structure.2.Alloying the steels with nitrogen is accompanied by a linear increase of the strength characteristics in short-term and long-term tests at room and elevated temperatures.The nitrogen-containing steels have the best combination of properties when microalloyed with boron.3.Increasing the nickel concentration in nitrogen-containing steels to the upper limit required to obtain a \gg solid solution has no effect on the mechanical or heat-resisting characteristics.
