Uniform Design and its Application in the Chemical Composition Design of Hot Work Die Steel
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 as follows: 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 on uniform design, six kinds of steels and the following heat treatment schemes were designed. The tempering resistance and the impact toughness at room temperature were measured. The results were analyzed by quadratic stepwise regression analysis, the relationships between the chemical compositions, the heat treatment processes and the properties were studied in detail, the influence coefficients and the influence tendencies of the main variables were also given in this paper.
