Conclusions

  1. 1.

    The contact strength of machine parts operating under various conditions of contact dynamic loading (cavitation-erosion, gas erosion, friction, and impact-abrasive wear) can be improved substantially by using Cr−Mn MAS steels.

  2. 2.

    The resistance of Cr−Mn MAS depends on the conditions of CDL, the rate of the martensitic transformation, and the properties of the phases formed. For applications involving cavitation we recommend steels containing 0.1–0.3% (C+N) of the 10Kh14AG12-30Kh10G10 type, in which the γ→ε and γ→α martensitic transformations occur at a high rate; steels with a high carbon content (0.6–0.8%) in which the γ→α transformation is the primary transformation under load (steels of the 60Kh5G10L-70Kh4G8L type) are promising for impact-abrasive wear conditions.
