Pressure die casting, forging, and extrusion: when the going gets hot, tool steels need to be tough – and especially clean. The special properties of BÖHLER hot-working steels are specifically tuned to withstand a wide range of loads, and especially for use in high-temperature applications. The cleanliness and homogeneity of these steels are critical for ensuring a long tool life. That is why we do everything possible to minimize non-metallic inclusions. This usually involves using innovative melting processes, such as the protective gas ESR method or vacuum arc remelting.
