Conclusions

  1. 1.

    Stepped quenching in the range 430–470°C does not increase the structural strength of steel 42Kh2GSNM.

     
  2. 2.

    To increase the structural strength of sheet steel 42Kh2GSNM it is recommended to carry out stepped quenching with holding near the lower boundary of the pearlitic range. This holding must not exceed the incubation period of carbon-enriched zones in the austenite which during the subsequent cooling become transformed into carbide phase.
