Bohler-Uddeholm UDDEHOLM DIEVAR® Hot Work Tool Steel

Description: Uddeholm Dievar is a high performance chromium-molybdenum-vanadium alloyed hot work tool steel which offers a very good resistance to heat checking, gross cracking, hot wear and plastic deformation.Dievar is characterized by: Excellent toughness and ductility in all directions Good temper resistance Good high temperature strength Excellent hardenability Good dimensional stability throughout heat treatment and coating operationsApplications: Heat checking is one of the most common failure mechanism e.g. in die casting and now days also in forging applications. Uddeholm Dievar’s superior ductility yields the highest possible level of heat checking resistance. With Uddeholm Dievar’s outstanding toughness and hardenability the resistance to heat checking can further be improved. If gross cracking is not a factor then a higher working hardness can be utilized (+2 HRC). Regardless of the dominant failure mechanism; e.g. heat checking, gross cracking, hot wear or plastic deformation. Uddeholm Dievar offers the potential for significant improvements in die life and then resulting in better tooling economy. Uddeholm Dievar is the material of choice for the high demand die casting-, forging- and extrusion industries.
