The method of quenching in tin melt was tested for low-weight parts with a large specific surface, made of a number of steels with a high temperature of the onset of martensitic transformation. The advantages of this method in comparison with traditional hardening technologies are established, as well as regularities in the change of cooling curves for various mass ratios of the part and the quencher are revealed. The practical possibility of adjusting the cooling rates in the process of hardening in various temperature ranges in order to optimize the phase ratio in steel while maintaining the possibility of preventing the occurrence of microcracks is shown.
