Wai Nickel Alloys, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, focuses on crafting top-notch Duplex Steel 2205 Flanges that are designed for outstanding strength, corrosion resistance, and durability. These flanges are produced using cutting-edge metallurgical techniques to guarantee precise dimensions, the ability to handle high pressure, and a long lifespan. Duplex 2205 Flanges are known for their remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, even in environments with chloride. Their impressive mechanical strength, along with good weldability and thermal stability, makes them perfect for critical applications in marine, oil & gas, petrochemical, and desalination industries where reliability is key.
Duplex Steel 2205 Flanges are made up of about 22% Chromium, 5–6% Nickel, 3% Molybdenum, and the rest is Iron, with controlled amounts of Nitrogen, Manganese, and Silicon. This duplex microstructure provides a well-balanced mix of austenitic and ferritic phases, leading to a tensile strength ranging from 700 to 900 MPa and a yield strength of around 450 MPa. The alloy excels in resisting chloride stress corrosion, oxidation, and erosion, while also maintaining impressive toughness and ductility. Duplex 2205 flanges keep their mechanical integrity even under high temperatures and pressures, ensuring dependable performance in challenging industrial settings.
