Auto Parts Tungsten Carbide Engine Exhaust Valve Seat
The cemented carbide seat, also known as the cemented carbide seal ring, has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance andcorrosion resistance, especially its high hardness and wear resistance, even at the temperature of 500℃ is basically unchanged, at 1000℃ still has a high hardness. Used with hard alloy valve core, has excellent sealing and wear resistance, alloy seat bevel is smooth and smooth.
- Standard
Product Introduction:
The cemented carbide seat, also known as the cemented carbide seal ring, has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance andcorrosion resistance, especially its high hardness and wear resistance, even at the temperature of 500℃ is basically unchanged, at 1000℃ still has a high hardness. Used with hard alloy valve core, has excellent sealing and wear resistance, alloy seat bevel is smooth and smooth.
Product Features:
1. Hard alloy seal ring with wear resistance, corrosion resistance and other properties, widely used in petroleum, chemical and
other fields of mechanical seal, the products are flat ring (PH) and table ring (TH) and other special-shaped rings,
specifications customized;
2. After fine grinding, the product has very small size and tolerance, and excellent sealing performance;
3. Rare elements of corrosion resistance are added to the process formula to make the sealing performance more durable;
4. Using high strength and high hardness of hard alloy material, no deformation, more compressive.
Product Use:
Mineral, and surface mining tools, drilling for oil and gas or horizontal directional drilling, mining and recycling process
mechanical sealing equipment, etc.
