（1）. Meetsthe requirements of working conditions
When the blank is plastic in the mold cavity, the surface of the cavity flows and slides along the surface of the cavity, which causes the friction between the surface of the cavity and the blank, which causes the die to fail because of the wear. So the wear resistance of the material is one of the most basic and important properties of the mold.
Hardness is the main factor affecting the wear resistance. […]
