    More Information

    Technology process: EAF+LF+VD+RS ESR, Unique technology of rapid solidification electro slag smelting, which can greatly improve the performance of the internal organization of high-speed steel, ledeburite meshes smaller and thinner, can make material high toughness, high wear resistance.
    Property Containing cobalt high-speed steel has the good high-temperature hardness and hot hardness, better machinability and wear resistance, high strength and impact toughness.
    Application It can be used for a variety of manufacturing and processing of hard cutting tools, such as gear cutter, milling cutter, punch, etc.
