3Cr2W8V Hardware Tool Steel Bar
3Cr2W8V is the alloy tool steel, is based on the carbon steel alloy elements formed by the formation of steel. One of the steel, including measuring tool cutting tool steel, impact resistance steel, cold work dies steel, hot die steel, non-magnetic die steel, plastic mold steel. 3Cr2W8V is hot work die steel. 3cr2w8v hot work dies steel, is commonly used die-casting mold steel, has a high strength and hardness, good cold and heat fatigue, and have good hardenability, but its toughness and plasticity is poor. For the production of high temperature, high stress, the impact load from the punch, die, such as die-casting mold, hot extrusion die, precision forging die, the non-ferrous metal molding die.
