Duplex Tube Fittings are mainly made up of around 22% chromium, 5–6% nickel, and 3% molybdenum, with the remainder being iron and trace amounts of nitrogen. Their unique dual-phase ferritic-austenitic microstructure gives them excellent tensile strength, high yield strength, and superior toughness. These fittings are highly resistant to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich or aggressive environments. They also exhibit great fatigue resistance, ductility, and thermal stability, ensuring consistent mechanical performance. The blend of corrosion resistance and mechanical strength makes Duplex Tube Fittings perfect for critical piping applications in challenging industrial settings.
