Characteristics of the material - Steel is a fine grade hot work die steel, which belongs to chromium, molybdenum and vanadium alloy tool steel and electroslag remelted steel. The steel has high cleanliness, good dissolution resistance, uniform structure, good thermal strength and toughness, and is resistant to erosion by high-temperature molten metal. It has excellent high temperature tempering resistance, the working hardness is not easy to drop below ℃, is resistant to cold and hot fatigue, and has strong crack resistance. Excellent thermal shock resistance, high high temperature strength, high toughness and ductility, good isotropy, excellent processability, hardenability and polishability, and good dimensional stability during heat treatment.
This steel is a steel with high purity and dense structure obtained by using special steelmaking technology and strict quality control. The isotropy (isotropy) of the steel is better than that of ordinary traditional steel refining. This is more valuable for the mold's resistance to fatigue and thermal stress fatigue. High hardness can slow down the occurrence of cracks and increase the service life of the mold.
