The use of 420 die steel quenching and tempering state (hardness 48-54HRC), in order to meet the long-term work or the number of parts up to 1 million or more life requirements, the more suitable use method should be quenching low temperature tempering treatment. Quenching is first heated to 1000-1050ºC to hold heat for a certain time (calculated at 30 minutes /25mm), and then quenched into the oil to cool to 50-100ºC and immediately temper treatment to prevent cracking. Tempering at 200ºC (at least 4 hours) hardness can reach more than 48HRC, with better polishing and better corrosion resistance.
