Effect of nitriding on the resistance to fracture of high-strength maraging steel N18K9M5T

Conclusions

  1. 1.

    With nitriding of high-strength maraging steel N18K9M5T the high resistance to fracture is retained to a considerable extent.

  2. 2.

    Nitriding does not change the ductile character of the fracture of the core observed after aging.

  3. 3.

    Nitriding can be recommended for surface hardening of heavily stressed machine parts of steel N18K9M5T. In this case it is necessary to impose more severe requirements with regard to defects as compared with machine parts subjected to quenching and aging.
