HOT WORK TOOL STEEL
HIGHEST PURITY STANDARDS
Die casting, forging and extrusion: When things get hot, tool steel has to be tough – and particularly pure. The special properties of BÖHLER and Uddeholm hot-work tool steels are specifically tailored to the different stresses, especially for use at high temperatures. The degree of purity and homogeneity of the steels is crucial for a long service life of the tools. That is why we do everything we can to minimize non-metallic inclusions and segregations as far as possible. Innovative melting processes, such as the protective-gas ESR process or vacuum arc remelting, are usually used for this purpose.
BÖHLER and Uddeholm hot-work tool steels are used in the industrial production of drop-forged and die-cast parts and, due to their good combination of properties, also in mechanical engineering and plastics processing. Our focus is on remelted steels, with which we offer our customers customized material solutions.
