Tungsten Carbide Seal Ring Material

The high-quality tungsten carbide seal ring medium containing suspended particles, the wear on the sealing ring is very serious, which requires the production of wear-resistant material sealing ring. This sealing ring is usually produced using chrome steel, carbon tool steel, bearing steel, high chrome cast iron and other materials, the shorter its life. Tungsten carbide with high hardness and strength, good wear resistance, long life with its sealing ring made ​​of, but the downside is brittle carbide, machining difficulties. As we all know, the process is generally the production of carbide with a good compression molding material at room temperature, and then the high-temperature firing. As the ring deformation is large, usually used to increase production to reduce the thickness of the ring deformation, not only multi-material, and post-processing required for a long time, so the price is expensive ring firing at high temperatures, which generally do not use hard alloy materials to do the sealing ring.
