Conclusions

  1. 1.

    For punching and coining die parts the optimum combination of properties (high hardness of the base and wear resistance of the surface and sufficient core toughness) is obtained with a combination of chemicothermal and heat treatments (with water quenching of the container) only for Kh12M and KhVG steels (and primarily with use of carbide coatings).

     
  2. 2.

    The following processes are recommended: for Kh12M steel chemicothermal treatment in a container with a fusible seal at 1050°C for 5 h, water quenching of the container with the parts; for KhVG steel chemicothermal treatment in a container with a fusible seal at 1000°C for 5 h, furnace cooling of the container, austenitizing in the same sealed container at 850°C for 2 h, water quenching of the container with the parts.

     
  3. 3.

    For punching and coining dies (taking into consideration the proposed chemicothermal and heat treatment process) use of high-chromium type Kh12M steel is most desirable.
