Our company has successfully developed a high-end die-casting die steel forging plate containing cobalt. After inspection, all product indicators meet customer needs. The material will be delivered to customers to replace imported materials of the same type and used in the manufacture of precision die-casting parts. High-end die-casting die steel containing cobalt can slow down the occurrence of thermal cracking due to its excellent heat shock resistance and high temperature hardness, thereby extending the service life of the mold. During the research and development process, our company's research team strictly controlled various component indicators in accordance with the requirements of low phosphorus and other requirements of the material, and ensured the uniformity of the composition through a series of process optimization and precise regulation; at the same time, key operating points such as casting time were strictly controlled to ensure that the composition and surface quality of the ingots achieved the expected results.
