5Cr4Mo3SiMnVAl 5Cr4Mo3SiMnVAl The steel is a steel substrate type of hot and cold dual-die steel, tool steel as a cold, it is compared with the carbon tool steel, low-alloy tool steel and Cr12 steel with high toughness; as hot die steel, it is compared with 3Cr2W8V steel with high temperature strength and relatively good thermal fatigue resistance.
Heat the steel industry for standard cold heading die and extrusion molding using the bearing industry, life has greatly improved than the original steel
