Description Of Stellite 6 Valve Balls & Seats

Stellite 6 Valve Balls & Seats are high-performance valve trim components manufactured from Stellite 6 (UNS R30006), a cobalt-chromium-tungsten alloy known for its exceptional wear resistance, corrosion resistance, and high-temperature strength. These components form the critical sealing interface in ball valves, check valves, and pump systems, controlling fluid flow in demanding industrial environments.

Stellite 6 contains approximately 28% chromium, 4.5% tungsten, and 1.2% carbon. Its unique microstructure, featuring hard carbide particles dispersed in a tough cobalt matrix, provides outstanding resistance to abrasion, erosion, and galling. The alloy maintains its hardness and mechanical properties at elevated temperatures up to 800°C, making it ideal for high-temperature and high-pressure valve applications.

Stellite 6 valve balls and seats are precision-matched and lapped to ensure reliable sealing performance. They are available in custom sizes and configurations, with surface finishes including machined, ground, lapped, and polished. Typical applications include oil and gas valves, chemical processing valves, and high-pressure valve systems.
