HOT LINE: +86-510-80628100HOT LINE: +86-510-80628100Hot work die steel H13 (Chinese grade 4Cr5MoSiV1) is a commonly used medium carbon chromium hot work die steel. Due to its excellent high-temperature strength, wear resistance, and thermal fatigue resistance, it is widely used in the manufacture of die-casting molds, hot forging dies, etc. Its forging performance is affected by various factors, and the forging process, as a key preparation step, directly affects the final mechanical properties of the material. Optimizing the forging process of H13 can effectively improve the mechanical properties of forgings, thereby enhancing their service life. A reasonable forging process can significantly improve the thermal fatigue resistance and high-temperature strength of materials by refining grain size and homogenizing carbide distribution. During the forging process of H13 hot work die steel, when using a fast forging machine for upsetting and stretching, due to the high pressure and axial and radial deformation ability of the fast forging machine, the forging penetration of the forging can be effectively improved. The upsetting and elongation of the fast forging machine can compact and weld the existing segregation, porosity, porosity, slag inclusion, etc. inside the steel ingot, making its structure more compact and improving the plasticity and mechanical properties of the metal.
