Tool steel generally has a higher carbon content than ordinary steel. Carbon is an important component in the hardness of steel. Due to its high carbon content, steel has a higher hardness after heat treatment. In addition to carbon, tool steel generally contains alloying elements such as chromium, vanadium, tungsten, and molybdenum. They are important elements in improving the hardness, wear resistance and other properties of steel. For example, chromium can increase the corrosion resistance of steel, while tungsten and molybdenum can increase the hardness and strength of steel.
