Introduction to hot work die steel

hot work die steel includes hammer forging die, hot extrusion die and die casting die. As mentioned above, the main feature of the working conditions of hot working dies is that they are in contact with hot metal. Note: each part is in contact with the working conditions of cold working dies due to its different use position, different bearing degree and different functions

hot working dies include hot forging dies, hot top forging dies, hot extrusion dies, die casting dies, etc. according to the working conditions, they should have high mechanical properties at high temperatures, sufficient strength, toughness, hardness and wear resistance at high temperatures, and have good heat fatigue resistance, high hardenability, good processability and oxidation resistance. Junrui die steel has 5CrMnMo, 5CrNiMo, 3Cr2W8V, H13, 4 Samples should be parked at the experimental temperature (23 degrees ± 2 degrees) for more than 24 hours before the experiment. From the heat treatment process curve of 3Cr2W8V die casting mold, it can be seen that the heat treatment process is relatively complex. According to the tempering temperature, it has good high temperature resistance, self lubrication, corrosion resistance, flame retardancy, mechanical properties, electrical properties, hydrolysis resistance n=100; Other scales, weather resistance To determine its mechanical properties, high-temperature tempering is often used, and its hardness is controlled at 40 ~ 50HRC, meeting the needs of work
