Tungsten Carbied Screw and Barrel

The material is alloy steel. Through various heat treatment to ensure that screw toughness of the core, and the hardness of binding sites, preventing hypertension undering pressure surface subsidence. Using the method of laser-coated nano-uniform coating of tungsten carbide in screw Face, tungsten carbide content of 90% and above, the density of 99.5%, the hardness of tungsten carbide coating layer HRC70-75, tungsten carbide coating thickness of 1mm. Our company unique laser coating technology and stringent quality control system that can protect its enduring hard, and the rupture and bond issues to control at least. New high filler and apply to high temperature and high wear materials processing, completely beyond various types of imported materials.
