COLD WORK TOOL STEELS


BÖHLER cold-working steels are used to produce tools that are not generally exposed to surface temperatures of more than 200°C. The main applications here are punching, fine blanking sheet metal forming, and massive forming. High hardness and wear resistance, resistance to fracture, low dimensional changes under heat treatment, and sufficient machinability are some of the most critical properties of these steels. And these are the properties that BÖHLER is continuously optimizing and developing, with the satisfaction of its customers in mind.

The reason for using quality tool materials for Cold Work is obvious, as the material amount of a high performance tool is often only 5% of the total value of a tool, yet it extends the lifetime of tools many times, it’s a direct commercial advantage in production. The products produced in electric arc furnace are described as conventionally molten materials and represent the “basic materials” for usual stress with main properties such carbide distribution in lines and sufficient purity degree.
