介绍 | 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:
Improved tooling performance Dievar is a premium hot work tool steel developed by Uddeholm. It is manufactured utilizing the very latest in production and refining techniques. The Dievar development has yielded a die steel with the ultimate resistance to heat checking, gross cracking, hot wear and plastic deformation. The unique properties profile of Dievar makes it the best choice for die casting, forging and extrusion. Applications Heat checking is one of the most common failure mechanism e.g. in die casting and now days also in forging applications. Dievar's superior ductility yields the highest possible level of heat checking resistance. With 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. Dievar offers the potential for significant improvements in die life as well as tooling economy. Dievar is the material of choice for the high demand die casting, forging and extrusion industries. |
