Abstract

The invention relates to a method for the production of tools for a chip-removing machining of metallic materials and to a tool with improved wear resistance and/or high toughness. The invention further provides an alloyed steel with a chemical composition comprising carbon, silicon, manganese, chromium, molybdenum, tungsten, vanadium, and cobalt as well as aluminum, nitrogen, and iron. The alloyed steel may be used to make tools to a hardness of greater than 66 HRC and increased chip-removing machining performance.
