Improved tooling performance
Uddeholm Dievar is a premium hot work tool steel developed by Uddeholm. It is manufactured utilizing the very latest in production and refining techniques. The Uddeholm Dievar development has yielded a die steel with the ultimate resistance to heat checking, gross cracking, hot wear and plastic deformation.he unique properties profile for Uddeholm Dievar makes it the best choice for die casting, forging and extrusion.
Hot work applications
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.
