Tungsten carbide valve stems and seats have high hardness and good wear resistance, so tungsten carbide material is usually used to make valve stems and seats. These characteristics make tungsten carbide particularly suitable for use in harsh environments such as oil and gas exploration, the machining industry, the injection moulding industry, Spray industry, the automotive industry and the aerospace industry.
Features
Excellent wear resistance Tungsten carbide valve seats are very hard and have excellent wear resistance. Under severe conditions such as abrasive wear, erosive wear and scuffing, the wear resistance of tungsten carbide is much higher than that of conventional materials such as tool steel and stainless steel, approximately 100 times higher.
High strength and rigidity The rigidity of tungsten carbide is 2 to 3 times higher than that of steel, and the impact resistance is similar to that of hardened tool steel. Therefore, tungsten carbide valve stem and seat can maintain stable performance even when subjected to high pressure and strong impact.
High temperature resistance Tungsten carbide is not easily decomposed at high temperatures, has good oxidation resistance, and can work stably for a long time in a high-temperature environment.
Corrosion resistance Tungsten carbide has good corrosion resistance and can be used in many kinds of corrosive media without being easily damaged by corrosion. Therefore, it is widely used in chemical and petroleum industries.
Long service life Tungsten carbide valve stem valve seat has a long service life under harsh working conditions, reducing replacement frequency and maintenance costs, and improving the overall efficiency and reliability of the equipment.
