Tungsten carbide sealing ring is a commonly-used component in the sealing ring market. So what is the cemented carbide sealing ring ? What are the characteristics? What is the main application field? Let's learn about it together.
1.What is cemented carbide sealing ring
Tungsten carbide sealing ring is made of tungsten carbide powder, adding appropriate amount of cobalt powder or nickel powder as a binder, pressed into a ring through a certain mold, and sintered in a vacuum furnace under high temperature around 1500℃. Because of its high hardness and good anti-corrosion performance, it is widely used in petrochemical and other sealing industries.
2.Properties of cemented carbide sealing ring
The material of the sealing ring has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500°C , It still has high hardness at 1000 °C. Tungsten carbide sealing ring has all the advantages of cemented carbide and has become a widely used product in mechanical seals.
Oston carbide has more than 10 years of mature experience in the production of cemented carbide sealing rings, and concluded that the cemented carbide sealing ring grades used by users are mostly YG6 and YN6 cemented carbide materials. YG6 cemented carbide sealing ring has higher hardness and wear resistance, while YN6 has relatively better corrosion resistance. 
Oston Carbide supplies cemented carbide sealing rings of various specifications, which can be customized according to the user's drawings. With high-quality cemented carbide materials and composite materials for sealing ring parts, it can effectively solve problems such as thermal cracks of mechanical sealing rings. The cemented carbide sealing ring has the following characteristics:
1) Small concentricity and high precision;
2) The cross-section has high flatness and excellent sealing performance;
3) High wear resistance and long service life;
4.) Stable quality and performance
3. Application of cemented carbide sealing ring
Tungsten carbide sealing ring has good wear resistance, high thermal conductivity, low friction coefficient, small expansion coefficient, acid resistance, alkali resistance and other relatively stable chemical properties, and is an ideal material for mechanical seals. It is widely used in the sealing of pumps, compressors, centrifuges, mixers and other machinery, as well as the sealing of pipelines in petroleum and chemical industries.
