Duplex 2205 Tube Fittings are crafted from a carefully balanced chemical mix, featuring around 22% chromium, 5–6% nickel, 3% molybdenum, and controlled nitrogen. This combination results in a dual-phase ferritic-austenitic microstructure that provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, Duplex 2205 boasts high tensile and yield strength, impressive fatigue resistance, and solid impact toughness, even in low temperatures. These characteristics ensure that the tube fittings maintain their structural integrity and long-lasting reliability in demanding industrial settings with high stress and aggressive environments.
