  1. 1.

    Steel 1Kh12VNMF of the ferritic—martensitic class can be nitrided at 680–1000°. The optimal treatment, ensuring high properties of the core and the case, consists of combining nitriding with tempering at 680°. This treatment produces a case of high hardness (HV 800), which increases the wear resistance. The strength of adhesion of the nitrided case to the core is fairly high.

  2. 2.

    Nitriding of steel 1Kh12VNMF substantially increases its heat resistance; the mechanical properties are quite stable.
