Duplex 2205 steel flanges are made of a balanced austenitic-ferritic microstructure, offering excellent strength and corrosion resistance. Chemically, they contain approximately 22% chromium, 5–6% nickel, 3% molybdenum, and 0.14% nitrogen, with low carbon (~0.03–0.05%) to enhance weldability. Mechanically, 2205 duplex flanges exhibit high tensile strength (≈620–720 MPa) and yield strength (≈450–550 MPa), along with good toughness. They provide superior resistance to stress corrosion cracking, pitting, and crevice corrosion compared to austenitic stainless steels, making them suitable for aggressive environments like chemical, oil, and gas industries, while maintaining dimensional stability under high pressure and temperature.
