entire range of tempering temperatures, without a significant decrease in notch toughness. The inclusion of freezing hardening for M398 steel has the potential technological significance, it is possible to achieve a hardness of 864HV when tempering at a te mperature of 500 °C compared to conventional hardening where the maximum hardness 845HV was measured, without a significant decrease in notch toughness. The measurements show that in the range of simulated heat treatment temperatures, there is no occurrence of tempering brittleness, which could lead to a serious failure during the operation of the injection equipment.
