You will find tungsten carbide valve seats and balls wherever operating conditions are considered "severe service." Key industries include: Oil & Gas (Upstream): In choke valves and Christmas tree valves handling sand-laden, high-pressure drilling mud and production fluids that would rapidly erode standard materials. Chemical & Process Industries: For handling corrosive, abrasive, or toxic slurries and powders, where valve failure could lead to dangerous leaks or costly process shutdowns. High-Performance Automotive: In racing engines with aggressive camshafts and no leaded fuel for lubrication, tungsten carbide seats prevent valve recession and maintain precise timing and compression. Power Generation: In feed pump recirculation valves and other critical services where erosion from high-pressure water (cavitation) is a major concern. https://www.carbure-tungstene.com/tungsten-carbide-valve-seats-and-valve-balls

Tungsten carbide is a composite material, consisting of hard tungsten carbide particles cemented together in a tough binder, usually cobalt. This unique structure gives it an unbeatable combination of properties: Extreme Hardness: It is significantly harder than steel, hardened stainless steel, and even many tool steels. On the Rockwell C scale, it often reaches HRC 70-90, making it highly resistant to abrasion and deformation. Exceptional Wear Resistance: This is its primary advantage. In applications with abrasive fluids, dry or dusty gases, or high-cycle operations, tungsten carbide components outlast their steel counterparts by orders of magnitude, reducing downtime and maintenance costs. Superb Compressive Strength: It can withstand immense pressures without deforming, ensuring a consistent seal and reliable operation under load. In short, tungsten carbide is chosen where failure is not an option and longevity is paramount. https://www.carbure-tungstene.com/tungsten-carbide-valve-seats-and-valve-balls
