Conclusions

  1. 1.

    With HTMT of 30KhGSA steel with subsequent tempering at 500–550°C, the fatigue limits are higher than with conventional heat treatment.

  2. 2.

    HTMT has a greater effect on grade 30KhGSA steel than on grade 40KhNMA steel. The fatigue strength and the fatigue limit after HTMT after quenching at 500–550°C are almost the same.
