Overview
3CR2W8V mold steel has high toughness and good thermal conductivity; At the same time, it contains a large amount of carbide forming elements such as chromium, tungsten, and vanadium, which increase the phase transition temperature and give the steel high high-temperature strength, hardness, and good heat fatigue resistance; Quench through. Suitable for manufacturing molds, cores, sprues, flow pins, high stress wax seals, hot shear blades, hot top forging dies, flat forging machine convex and concave dies, inserts, etc. for die-casting copper, aluminum, magnesium alloys that are subjected to high temperature, high stress but not impact loads.
Product Details
3CR2W8V mold steel
It is a type of material that contains a high amount of easily formed carbideschromiumSteel with tungsten element.
3Cr2W8VsteelThere is a higher temperature at high temperaturesintensityandhardness, in650℃The hardness reachesHB～300But its toughness and plasticity are poor. Steel section in80mmThe following ten can be quenched. This surface layer needs to have high hardness andwear resistanceThe Large Topforging dieHot press molds and flat forging machine molds are already sufficient. This type of steel has a higher transformation temperature and good resistance to thermal fatigue caused by alternating cold and heat.
