Duplex Steel 2205 Flanges are produced from alloys with a balanced austenitic and ferritic microstructure. The composition includes chromium, nickel, molybdenum, and nitrogen, providing superior corrosion resistance and mechanical strength. High chromium and molybdenum content enhance resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, these flanges offer high tensile and yield strength, excellent toughness, and good fatigue resistance, enabling them to withstand high pressure, temperature variations, and harsh chemical environments.
