Hot work tool steels are alloyed tool steels for use where the surface temperature is generally above 200 °C. During use, the tool comes into short-term contact with hot, partly liquid metallic materials with a temperature well above 200 °C. In addition to a permanent thermal load, the tool steel is also subjected to temperature change stress. These high temperature changes cause high stresses on the tool contour, which only metallurgically high-purity materials can withstand. Voestalpine BÖHLER Edelstahl offers a wide range of tailor-made materials, from conventional grades for standard applications to electro slag remelted materials, for demanding applications, to alloys melted in vacuum arc furnace for the highest performance in die casting.
