Thanks to superior material properties, Uddeholm’s customers get reliable tools and components. What is Tool Steel ? Tool Steel Selection. For example, some tooling fails due to abrasive wear, in which the material being cut wears down the tool surface, though this type of failure is slow to occur and can be anticipated. Choosing the optimal tool steel grade will depend on many factors, including: Tool steels are available in a wide range of grades, based on their composition, the temperature range in which they were forged or rolled, and the type of hardening they have undergone. D Type (D-Grades) This is a high carbon, high chromium (air hardening) tool steel. Tool steels are wear-resistant, ferrous alloys based on iron and carbon with high levels of alloying (hardenability and property modifying) elements such as chromium, molybdenum, tungsten, and vanadium. means that a given grade of tool steel should be heat-treated differently if it is to be used as a stamping tool versus a cutting tool. Hot Working Tool Steels. D-2 steel can be either oil-hardened or air-hardened, and contains a higher percentage of carbon and chromium than O-1 and A-2 steel. Some operate under cryogenic conditions. Some fail because of severe abrasive or adhesive wear, others fail because of cracking, chipping, or plastic deformation. UNLIMITED Vacuum quenched and air quenched steel.
