Notes:
According to the conditions that hot work die steels, for example H13 and HOTVAR,were used, the main chemical compositions and the ranges of their contents were determined asfollows: 0.25~0.6%C, 0.5~1.5%Si, 0.2~1%Mn, 2~6%Cr, 1~3%Mo and 0.3~1.5%V. Based onuniform design, six kinds of steels and the following heat treatment schemes were designed. Thetempering resistance and the impact toughness at room temperature were measured. The resultswere analyzed by quadratic stepwise regression analysis, the relationships between the chemicalcompositions, the heat treatment processes and the properties were studied in detail, the influencecoefficients and the influence tendencies of the main variables were also given in this paper
