Chromium hot-work tool steels are designated as group H steels according to the AISI classification system.  Mathews, J. The graph bars on the material properties cards below compare annealed SAE-AISI A2 to: tool steels (top), all iron alloys (middle), and the entire database (bottom). This is why it’s so important to understand the properties of different tool steels, as well as other factors such as the geometry of the die, the material being worked, and the manufacturing history of the tool itself. The H-SS M2 chemical composition gives a good combination of well-balanced toughness, wear resistance and red hardness properties. This series of steels start from H1 to H19. Tool steels are a family carbon and alloy steels having distinct characteristics such as hardness, wear resistance, toughness, and resistance to softening at elevated temperatures. Keep in mind, however, that tool steel properties are not directly related to each other, so for instance, you may need to sacrifice toughness for higher wear resistance. Both of them contain alloying elements that give them necessary properties for certain applications. C45U can be used for components that need good machinability and wear resistance but do not justify the additional costs of an alloyed tool steel. Our tool steel meets the requirements of your individual application. Tool steels are used to form, cut, shear and mold metals and other materials.
