3cr2w8v hot die steel, tool steel die is used, a higher strength and hardness, good resistance to thermal fatigue, and better hardenability, but its poor toughness and ductility. Applicable to production of high temperature, high stress, the impact load from the punch, die, as die casting, hot extrusion mold, forging mold, molding and other non-ferrous metals.

Uses: Commonly used die-casting mold steel. Lower carbon content, higher toughness and good thermal conductivity; the same time, contains more carbon atoms of chromium, tungsten, vanadium, phase transition temperature increase, the steel has high temperature strength, hardness and good thermal fatigue; hardenability. Suitable for high-temperature, high stress, but not shock load the die-casting copper, aluminum, magnesium alloy with mold, core, gate sets, split nails, high should beat wax, hot shear knives, hot forging die , flat forging machine punch and die, inserts and so on.
