The working conditions of the stamping die are complicated because it bears the loads of impact, vibration, friction, high pressure, tension, bending and torsion, and even works at a higher temperature (such as cold extrusion).

It is prone to wear, fatigue, fracture, deformation and other phenomena. Therefore, the requirement for the material of the working parts of the die is higher than that of the ordinary parts.

Due to the different working conditions of various stamping dies, the requirements for the materials of working parts of the dies are also different.

1. Material requirements for blanking dies

High wear resistance and hardness are required for working parts of sheet blanking dies, while high wear resistance and compressive yield point are required for thick sheet blanking dies.

To prevent the die from breaking or cutting edge collapse, it should also have high fracture resistance, high flexural strength and toughness.

2. Requirements for Drawing Die Materials

It is required that the materials of working parts of dies and moulds have good anti-adhesion (anti-occlusion), high wear resistance and hardness, certain strength and toughness, and good cutting performance, as well as heat.
