OPTIMIZATION OF TEMPERATURE HARDENING FOR IMPROVING THE HEAT RESISTANCE OF TOOL STEEL 4Х5MФ1С IN VARIOUS WORKPIECES. PART 2. THE CHOICE OF THE MODE OF HARDENING STEEL 4Х5MФ1С TO INCREASE THE HARDNESS AND HEAT RESISTANCE AFTER TEMPERING
A new mode of heat treatment, including oil quenching from temperature 1150 °C with tempering at 500–650 °С for 1,5 hours was developed. The effect of increasing the level of hardening and the heat resistance is determined by more complete dissolution of the steel matrix, the coarsening of grains an...
