With the comprehensive performance of “high strength+corrosion resistance+wear resistance+temperature resistance”, alloy valve seat has become a key component of industrial valves to cope with severe working conditions. Its design logic always revolves around “sealing reliability, environmental adaptability and life economy”. Through material selection, structural optimization and surface treatment, it plays the core role of “preventing leakage and ensuring safety” in high-end fields such as petroleum, chemical industry and energy. The main materials include:
