Tool steel is the steel used to produce cutting tools, measuring tools, molds and wear-resistant tools.
Tool steel has high hardness and can maintain high hardness and red hardness at high temperatures, as well as high wear resistance and appropriate toughness.
Tool steel is generally divided into carbon tool steel, alloy tool steel and high-speed tool steel.
Folding hardness:
Tools made of tool steel have a high enough hardness after heat treatment, such as tools used for metal cutting processing are generally above HRC60.
The tool can still maintain high hardness and good red hardness under high cutting speed and high temperature heating conditions generated by processing hard materials.
Carbon tool steel and alloy tool steel generally at 180 °C ~250 °C, high-speed tool steel at about 600 °C operating temperature, still can maintain a high hardness.
Red hardness is a very important property for steel used in hot deformation molds and high-speed cutting tools.
Folding wear resistance:
Tool steel has good wear resistance - the ability to resist wear. The tool maintains its shape and size under considerable pressure and friction.
Folding strength toughness:
Tool steel has a certain strength and toughness, so that the tool can withstand complex stresses such as vibration, bending, load and impact in the work to ensure the normal use of tools.
Folding other properties:
Due to the different working conditions of various tools, tool steel also has some other properties, such as mold steel should also have a certain high temperature mechanical properties, thermal conductivity, thermal fatigue and wear-resistant corrosion properties and so on.
