Following is the introduction of company: 3.Tool steel is steel used to make cutting tools, gauges, molds and wear tools. The tool steel has high hardness and high hardness and red hardness at high temperatures, as well as high wear resistance and proper toughness. Tool steel is generally divided into carbon tool steel, alloy tool steel and high speed tool steel. Steel for the manufacture of various cutting tools, cold and hot deformable dies, gages and other tools, collectively referred to as tool steel. Various tool steels have common requirements, such as high hardness, good wear resistance and certain toughness and strength, and have their own special requirements, such as red hardness, impact resistance, dimensional stability, thermal fatigue resistance and Good overall mechanical properties, etc. In order to meet these different requirements, tool steels of various compositions are used in production and their performance requirements are met by appropriate heat treatment processes. Tool steel is often divided into three categories: carbon tool steel, alloy tool steel, and high-speed steel (essentially high alloy tool steel). According to the use of steel, it can be divided into three categories: cutting tool steel, die steel and measuring steel. The service life of tool steel is closely related to the quality of heat treatment. The heat treatme |
