Basic properties of tool materials

The material of the tool must have high high temperature hardness and wear resistance, the necessary bending strength, impact toughness and chemical inertness, good process (cutting, forging and heat treatment, etc.), and not easy to deform. Usually when the material hardness is high, the wear resistance is also high; the bending strength is high, the impact toughness is also high. However, the higher the hardness of the material, the lower the flexural strength and impact toughness.
