Polishing Surface Tungsten Carbide Bushing Hardened Steel Bushes Mold
Introduction:
As the main material of cemented carbide valve seat, cemented carbide also has the performance of cemented carbide, that is, longer working time, corrosion resistance and wear resistance, and can withstand high pressure. When tungsten and carbon are combined together, they become the hardest substance in tungsten carbide. When parts and equipment wear out, the application of cemented carbide to weld hard surface materials is the fastest and most convenient way. Its versatile and flexible way of application can not be surpassed. China Tungsten supplies all kinds of products online to meet different needs. Cemented carbide cemented carbide will reduce the wear and tear of various mining and processing processes, such as ore, minerals, agriculture, construction, and surface mining tools, drilling for oil and gas or horizontal directional drilling, mining and cycling.
