Product Description Tungsten Carbide Valve spares We can supply tungsten carbide valve spars with high precision. With high corrosion and wear resistance and high strength and temperature resistant,our tungsten carbide valve spares export to most of countries in the world. Tungsten carbide valves spares' materials covers: cobalt carbide,nickel carbide,tanium carbide and so on. Both standard and nonstandard parts according to the customers' drawings or samples are all available from us.Our AdvantagesOur Advantages:1:High strength, high wear resistance, high precision, high temperature resistant, corrosion resistant.2:They are mainly used for the sealing of valves of oil pumps in petroleum industry's sand containing wells, viscous oil wells, sea oil wells and high pressure sulfur resistant oil wells, etc.3 They are used with compatible cemented carbide valve seats. The surface finish, tolerance class and tolerances of dimensions have respectively reached the standards of the machine industry: G5, G10, G16, G40 and G100 of JB/T 9145-1999.4:Precision machined cemented carbide balls of other grades and specifications are also available based on customers' demands.5:Compatible high precision valve seats can also be made available.Product DescriptionYG6 YG8 tungsten carbide ball for valve pair & oil industry Product Description1: Diameter: ?0.3~?100mm2: Application :Tungsten carbide ball is very wide, such as: precision parts punching and drawing, precision bearing, instrument, instrument, pen making, spraying machine, water pump, mechanical fittings, sealing valve, brake pump, punching hole, oil field. Hydrochloric acid laboratory, hardness measuring instrument, fishing gear, counterweight, decoration, finishing and other high-end industries Product name Tungsten carbide balls Series YG6 YG8 YN6 YN8Feature Large hard Tungsten Carbide ball has high hardness, wear resistance, corrosion resistance, bending resistance, and bad use environment, and can replace all steel ball products. Carbide ball hardness ≥ 90.5, density = 14.9g/cm3.Density 14.9g/cm3Product process line The production process of cemented carbide ball is similar to that of other cemented carbide products, mainly including powder preparation → recipe according to application → wet grinding → mixing → crushing → drying → sieving → adding molding agent → drying → sieving Prepared mix → granulation → cold isostatic pressing → forming → sintering → forming (blank) →grinding → packaging → storage. According to the specific application requirements and related parameters, there are carbide alloy ball, tungsten steel ball, tungsten ball, high-density alloy ball and other carbide ball products. The smallest carbide ball can do about 0.3 in diameter.Product ParametersVarious Size of Aseeder tungsten carbide balls in many types of tungsten carbide grade are availableGradeDensity ( g/cm3)Hardness ( HRA)T.R.S(MPa)Grain size ( μm)Composition ( % )Equal to ISOYG814.65~14.85≥89.5≥23201.2~2.08%CO 92%WCK20YG614.85~15.05≥90.0≥21501.2~2.06%CO 94%WCK10Dia.(mm)Dia.(inch)Dia.(mm)Dia.(inch)23/38823/732.381253/329.5253/82.56/611037/9432/1711.11257/163.1751/81243/913.9695/3212.71/243/1913.49417/324.76253/161443/78512/6114.28759/165.5567/321513/22613/5515.8755/86.351/41617/2778/2919.053/47.9385/162037/47Tolerances: AFBMA Ball Tolerances TableGradeSphericity in inchesSphericity in mmBasic Diameter Tolerance in inchesBasic Diameter 2 in mmMaximun Surface RoughnessG30.000003"0.0000762mm+/-0.00003"+/-0.000762mm0.5G50.000005"0.000127mm+/-0.00005"+/-0.00127mm0.8G100.000010"0.000254mm+/-0.0001"+/-0.00254mm1G250.000025"0.000635mm+/-0.0001"+/-0.00254mm2G500.000050"0.00127mm+/-0.0002"+/-0.00508mm3G1000.0001"0.00254mm+/-0.0005"+/-0.0127mm5G2000.0002"0.00508mm+/-0.001"+/-0.0254mm8G5000.0005"0.0127mm+/-0.002"+/-0.0508mm G10000.001"0.0254mm+/-0.005"+/-0.127mm Detailed PhotosPackaging & Shipping contact us to get More information and sample EVERGREEN HARDMETAL TOOLS CO.,LTD
