DVA DVA-Nb Hot Work Tool Steel High Impact Toughness And High Isotrapy High Temperature Strength

Hot working die steel is a kind of alloy tool steel used for die forming by pressing solid or liquid metal above phase transition temperature, such as hot forging die steel, die casting die steel, hot stamping die steel, etc. Because the hot working die is in service for a long time under the conditions of high temperature and high pressure and alternating hot and cold, the hot working die steel must have excellent strength and toughness ratio, especially excellent thermal stability and thermal fatigue resistance.

Guangda DVA hot working die steel, with excellent toughness and thermal fatigue resistance, at the same time has good high temperature strength and anti-tempering stability, is a high-quality universal hot working die steel, widely used in the field of hot working.
