The service life of tool steel is closely related to the quality of its heat treatment. The characteristics of the heat treatment of tool steel is that the pre-heat treatment is mostly spheroidized annealing to obtain uniform and moderate particle size spheroidized structure, and the final heat treatment is quenching and low temperature tempering (quench and 560C tempering for three times for high speed steel). In order to obtain the tempered martensite matrix distributed in the uniform fine carbide high hardness structure, to ensure the wear resistance of the tool.
