APPLICATION
H11 steel is widely used in the field of hot work mold manufacturing, especially suitable for high-temperature working conditions such as die-casting molds, hot forging molds, and extrusion molds. The excellent heat resistance and thermal fatigue resistance of H11 steel make it outstanding in aluminum alloy, magnesium alloy die-casting, and automotive parts hot forming, and can withstand high temperature repeated impacts below 600 ℃.
H11 steel is also commonly used in high-precision injection molds, especially for the molding of engineering plastics and optical grade plastics that require long-term stable production. The excellent polishing and wear resistance of H11 steel ensure long-lasting surface smoothness of the mold, reduce maintenance requirements, and are suitable for high demand injection molding production in industries such as electronics and home appliances.
H11 steel is also used in the manufacture of industrial cutting tools and wear-resistant components, such as hot shear knives, high-temperature fixtures, and extruder screws. The high toughness and wear resistance of H11 steel enable it to maintain excellent performance even under heavy loads and high temperatures, making it widely used in the fields of mechanical processing and high-temperature equipment manufacturing.
H11 STEEL CHARACTERISTICS
H11 steel, also known as the American air cooled hardened hot work mold steel, is one of the three most commonly used hot work mold steels in the European die casting industry. It has good comprehensive mechanical properties and can maintain high strength and toughness from room temperature to 600 ℃. The carbides in this steel are small and evenly distributed, with good resistance to cold and hot fatigue and corrosion, good cold and hot processing performance, good hardenability, and good thermal strength, oxidation resistance, high toughness, and wear resistance at medium temperatures. It is widely used due to its excellent comprehensive mechanical properties and thermal fatigue resistance.
In terms of chemical composition, the carbides in H11 steel are very small and evenly distributed. This characteristic endows H11 steel with excellent cold and hot fatigue resistance and corrosion resistance. At the same time, it also has good cold and hot processing performance and hardenability.
In terms of physical properties, H11 steel exhibits good thermal strength, oxidation resistance, as well as high toughness and wear resistance at medium temperature. These characteristics enable H11 steel to maintain stable performance in various harsh environments. In addition, H11 tool steel also has good high-temperature strength, excellent toughness and ductility in all directions, excellent hardenability, and a high level of thermal shock resistance and thermal fatigue.
In summary, H11 steel is a hot work mold steel with excellent comprehensive performance, widely used in industries such as automobiles, aviation, and electronics. Its chemical composition and production process have a significant impact on its performance. H11 steel with good comprehensive properties can be obtained through a reasonable heat treatment process. Attention should be paid to preventing corrosion, oxidation, decarburization, wear, and fatigue during use.
