Duplex Tube Fittings consist primarily of about 22% chromium, 5–6% nickel, and 3% molybdenum, with iron and small quantities of nitrogen making up the rest. Their distinctive two-phase ferritic-austenitic microstructure provides them with outstanding tensile strength, elevated yield strength, and exceptional toughness. These fittings offer strong resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-heavy or harsh environments. They also demonstrate excellent fatigue resistance, ductility, and thermal stability, delivering reliable mechanical performance. This combination of corrosion resistance and mechanical strength makes Duplex Tube Fittings ideal for essential piping applications in demanding industrial conditions.
