Vacuum heat treating tool & die materials

Abstract :

Modified vacuum furnaces for heat treatment of nonferrous metals, steels and superalloys include automatic process control systems that modulate pressures and velocity of gas in the furnaces to enhance heating and cooling rates of the furnace. Pressure and velocity modulations enable incorporation of any desired cooling temperature for preparing any grade of alloy steels and tool steels, with the cooling rate determining the level of part distortion. Convection heating processes with inert gas at low temperatures enable appropriate high-pressure quenching, tempering and hardening of the materials.
