Application scope of hot work die steel
Hot working die steel refers to alloy tool steel suitable for making dies for hot deformation of metal, such as hot forging dies, hot extrusion dies, die casting dies, hot upsetting dies, etc. Because the hot working die works under high temperature and high pressure for a long time, the die material is required to have high strength, hardness and thermal stability, especially high thermal strength, thermal fatigue, toughness and wear resistance.
