Tool and Die Steel Quenching Heating Time
Heating time of quenching is one of the most important parameters when designing the quenching process of die steel, directly related to its quenching quality. Customarily, when the furnace temperature t1 is below the Ac3 of pearlitic steel, the quenching time should be t2≥2t1, and when t1≥Ac3, ......
