Beijing YONGGU Yuntong Surface Alloy Technology Co., Ltd.   

        tungsten carbide - the national invention patent technology development ladder of advanced wear-resistant materials, tungsten carbide by high-energy ion injection into the steel matrix in the form of high wear-resistant alloy, 1.2-1.5 mm thick, the wear-resistant alloy products for severe wear conditions, as magical wear-resisting function! Steel surface infiltration of tungsten carbide, referred to as super wear resistant alloy. Instead of quenching, carburizing and quenching steel and high chromium, high manganese steel, the wear resistance of the surfacing material substitution, spraying, ion nitriding surface modification, to replace the high alloy tool steel, high-speed steel, imported wear resistant steel and wear resistant steel plate, the service life than the substituted material increased 3 - 8 times.
