Conclusions

  1. 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. 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. 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.
