9. Hardness & tempering relationship:

*0. Properties :

Under medium temperature conditions, it has good toughness, thermal fatigue and wear resistance. High thermal strength and hardness. Less thermal deformation and less oxide skin when air quenching, erosion against molten aluminum.

*1. Application :

Widely used in making hot extrusion die , core rod, pressing forging die, forging hammer die and precision forging die. And also used for the cooper and aluminum and alloy casting die .
