The effects of various heat treatments on hot die steel X20CoCrWMo10-9 were investigated.By analyzing phase structure,microstructure and properties of the steel,optimal quenching temperature of 1 120 ℃ was identified.It was also found that deep cryogenic treatment would improve the hardness and abrasion performance of the steel.After comparison between performances at different tempering temperature and for different length of time,it was concluded the desirable heat treatment process should include the following steps: quenching at 1 120 ℃ plus 8 h deep cryogenic treatment plus 1 h tempering at 650 ℃.
