Duplex Steel 2205 flanges are crafted from a well-balanced blend of about 22% chromium, 5–6% nickel, 3% molybdenum, along with nitrogen additions that boost strength and corrosion resistance. This unique dual-phase microstructure of austenite and ferrite results in remarkable mechanical properties, such as high tensile strength, excellent yield strength, and impressive fatigue resistance. Duplex 2205 also shows exceptional resistance to pitting, crevice corrosion, and stress-corrosion cracking, particularly in chloride-rich environments. Its thermal conductivity, hardness, and good weldability make it a reliable choice for challenging service conditions.
