Cold work steels tool are normally used at room temperatures featuring good wear resistance, toughness and dimensional stability. Since they operate at room temperatures high temperature resistance is not required. We normally classify cold work steels into 3 categories:
The most important properties looked into Cold work steels tool dies are:
To achieve wear resistance higher hardness is recommended. For better impact strength steels with better toughness are suggested. Toughness normally depends on the Hardness level and the Microstructure of the steel like Carbide distribution, grain size, inclusion ratings etc.
