Wai Nickel Alloys, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, focuses on crafting high-performance Super Duplex Steel Ball Valves known for their outstanding durability, corrosion resistance, and operational efficiency. Made from top-quality Super Duplex alloys, these valves are engineered to endure extreme pressures, temperatures, and harsh environments. Their well-balanced austenitic-ferritic microstructure offers excellent protection against pitting, crevice corrosion, and stress corrosion cracking. Super Duplex Ball Valves guarantee leak-free performance, smooth operation, and a long lifespan, making them perfect for industries like oil & gas, marine, chemical, and desalination applications.
Super Duplex Steel Ball Valves consist of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–4%), with Iron making up the balance, along with controlled amounts of Tungsten, Copper, and Nitrogen. This unique alloy delivers impressive tensile strength (800–1000 MPa) and yield strength (~550 MPa), ensuring remarkable toughness and resistance to fatigue. The dual-phase structure significantly boosts resistance to chloride-induced corrosion, oxidation, and erosion, even under high-pressure and high-temperature conditions. These valves maintain their shape and sealing performance, providing excellent weldability and machinability, making them ideal for complex fluid control systems in demanding industrial settings.
