AISI S7 tool steel be made of chromium-molybdenum alloy to satisfy the needs of high impact toughness. The chemical composition of Cr is quite high. So it has good tempering resistance, high-temperature oxidation, wire-electrode cutting property and impact toughness. After annealing softening treatment, the rolling steel bar must take the process of heating before the use. Because of the higher toughness and high-temperature oxidation, S7 steel material is widely used in the plastic mold, cold work and hot work tools that working in the high temperature and impact condition.
