Detail Information

Introduce:

This material is used in punching, cold solid forming, deep drawing, coining and cold extrusion processing methods. During cold solid forming, materials are transformed into their final shape by cold forming or extrusion. Depending on the method employed, the forming tools can be exposed to extremely high wear resulting from pressure and abrasion.The coining or embossing process, especially the minting of coins, creates unusually high demands on the steels used for punches and dies when it comes to purity, compression strength and wear resistance.

 

In the mints where the coins are produced, even the slightest divergences relating to surface, dimensional or gravimetric accuracy result in the tools being taken out of service. This strongly underlines the importance of the tool steel quality employed.

Application
This material is used in the top heads and dies of machines that press metal materials. Small round steel bars made by hot rolling or forging have a good cold stamping capability.
