Conclusions

  1. 1.

    To determine the effectiveness of thermomechanical hardening of steel 30KhGSA with high ductility after low-temperature tempering it is necessary to make fracture toughness and fatigue tests.

     
  2. 2.

    The best properties of steel 30KhGSA are obtained after HTMT at 950–1000°C with 20% deformation and tempering at 250°C. Increasing the postdeformation holding time to 10 sec at these temperatures improves the fracture toughness characteristics.
