3Cr2W8V Mold Steel Chemical Composition

2019-04-04
3Cr2W8V mold steel is a commonly used die-casting die steel with high strength and hardness, good resistance to cold and heat fatigue, and good hardenability, but its toughness and plasticity are poor. It is suitable for making punches and concave molds under high temperature and high stress without impact load, such as die-casting mold, hot extrusion die, precision forging die, non-ferrous metal forming die, etc.

3Cr2W8V steel application:

3Cr2W8V mold steel is a commonly used die-casting die steel. Low carbon content, high toughness and good thermal conductivity; at the same time, it contains more carbide forming elements such as chromium, tungsten and vanadium, and the phase transformation temperature is increased, which makes the steel have high high temperature strength, hardness and good heat resistance. Fatigue; hardenability. Suitable for the manufacture of high temperature, high stress, but not impact load, die-cast copper, aluminum, magnesium alloy with die, core, sprue bushing, split nail, high stress embossing, hot shearing knives, hot forging die, Flat forging machine convex and concave molds, inserts, etc.

3Cr2W8V mold steel chemical composition: C 0.30~0.40, Si≤0.40, Mn≤0.40, Cr 2.20~2.70, W 7.50~9.00, V 0.20~0.50, p≤0.030, S≤0.030
We can also hot work mold steel, cold work mold steel and plastic mold steel.
