Each flange is produced to meet stringent industrial standards, ensuring reliable performance in demanding environments. Duplex Steel 2205 Flanges are engineered for use in chemical, petrochemical, oil and gas, and marine applications, providing long-term structural integrity and operational efficiency. By combining advanced manufacturing processes with skilled craftsmanship, Bilal Nickel Alloys delivers solutions that support safe, efficient, and durable operations across critical industrial sectors requiring high-performance alloy components.
Duplex Steel 2205 Flanges are made from a chromium-nickel-molybdenum stainless steel alloy with a balanced ferrite and austenite microstructure. The alloy typically contains approximately 22% chromium, 5–6% nickel, 3% molybdenum, and small amounts of nitrogen. This composition provides outstanding resistance to pitting, crevice, and stress corrosion cracking. Mechanically, Duplex 2205 exhibits high tensile and yield strength, excellent toughness, and superior fatigue resistance. It also offers good weldability and formability, making it ideal for flanges that require both long-term mechanical reliability and corrosion resistance in harsh industrial environments.
