A better durability of the tool can be achieved due to an intelligent use of the raw material which ensures an economic production and also a high productivity. There are also for the cold work steels more and more high demands. This results from modern production machines for optimizing of manufacturing processes as well as the continous rising demands on the quality of the manufactured products. The temperatures are different; normally under 200°C surface temperature. For achieving the best material’s characteristics and also a long durability the coordination of the alloys is really important. Due to a different use of chrome, molybdenum, vanadium and tungsten the requested characteristics can be achieved with different steels. A distinction is drawn between cold work steels for cuts + cutting tools and cold work steels for stamping and piercing dies.
