Powder Metallurgy HOP HSS

Powder metallurgy HOP HSS is featured by its fine and evenly distributed carbides in the matrix, and therefore has the special preoperties of high toughness in all directions. As compared to HSS produced through other metallurgical process, the PM HSS can

    HEYE HOP series products are powder metallurgically produced high speed steels featured by its fine and evenly distributed carbides particles in the matrix. Because of its refined microstructure, HOP products are isotropic and high in  ductility, wear resistance, toughness as compared to traditional HSS. It is worth to mention that the bending strength and the toughness of PM HOP products are 50-100% better than that of normal HSS. Comparing to carbide, the PM HOP products have good machinability and grindability and are better choice for the materials of complex shaped cutting tools.
    Many success cases for the PM HOP products used as the tool materials of large size, complex shape in automotive, aviation, aerospace, energy industries. HOP products can really be a problem solver tool materials due to its refined microstructure which cannot be matched by the traditional HSS containing a lot of irregularly distributed coarse carbides.
    Cutting tools of PM HOP materials can use higher cutting speed under dry cutting conditions with relatively satisfactory tool life. It is one of the effective method to improve the productivity and reduce the machining cost.
