Conclusions

  1. 1.

    Nitriding of martensitic stainless steel in the metastable austenitic condition produces high strength of the base metal (up to 120–140 kgf/mm2).

     
  2. 2.

    Isothermal nitriding of steel 10Kh13 can be conducted at 500–550° for as long as 4 h, and steel 12Kh17N2 can be nitrided at 500–600° for the same time.

     
  3. 3.

    The nitrided case is formed at a higher rate than during nitriding in the pearlitic condition with depassivators, which is due to cleaning of the surface in vacuum.
