What is tool steel
Tool steels have good strength, toughness, hardness, wear resistance, and tempering stability. According to their different uses, tool steel can be divided into cutting edge, mold, and gauge steel. Depending on its chemical composition, tool steel can be divided into carbon, alloy, and high-speed steel.
High hardness and wear resistance are among the most important properties of tool steel. High wear resistance ensures and improves the tool life under the necessary conditions. In addition, different uses of tool steel have their own special performance requirements; for example, cutting edge steel also requires red hardness and a certain degree of strength and toughness, and gauge steel also requires high dimensional stability. High hardness, high wear resistance is one of the most important tool steel performance. High wear resistance ensures and improves the tool life under the necessary conditions. In addition, different uses of tool steel have their own special performance requirements; for example, cutting edge steel also requires red hardness and a certain degree of strength and toughness, and gauge steel also requires high dimensional stability.
Tool steel can be mainly used to manufacture various cutting, molding, and measuring tools.
The main properties of tool steel include hardness, wear resistance, strength, toughness, machinability, quenching temperature range, hardenability, decarburization sensitivity, heat treatment deformation, grinding, etc..
