h11 steel is the American air-cooled hardening hot work die steel. This steel is one of the three most commonly used hot work die steels in the European die casting industry. The steel has small carbides, uniform distribution, thermal fatigue resistance and corrosion resistance. Good, good cold and hot workability, good hardenability, thick thermal strength, oxidation resistance, high toughness and wear resistance at medium temperature..
This steel is one of the three most commonly used hot work die steels in the European die-casting industry. The steel has fine carbides, uniform distribution, good cold and hot fatigue resistance and corrosion resistance, good cold and hot workability, and good hardenability. At medium temperature, it has thick thermal strength, oxidation resistance, high toughness and wear resistance. The toughness of this steel is slightly higher than that of H13 steel, and it needs heat treatment. Generally, the applied hardness is 50-54HRC. This steel is commonly used in Europe for fixed and movable mold inserts. The steel concentrates high hardness and high toughness, and meets many requirements of hot work mold steel. The main alloy components are chromium, molybdenum and vanadium. It is remelted by electroslag Smelt.
