Duplex Steel Pipe Fittings have a distinctive chemical composition, usually consisting of about 22% chromium, 5-6% nickel, and 3% molybdenum, which offers superb resistance to corrosion, particularly against chloride-induced stress corrosion and pitting. Mechanically, duplex steel is characterized by high tensile and yield strength approaching double the value of common austenitic stainless steels, together with superior fatigue strength and toughness. Physically, they show high thermal conductivity, reduced thermal expansion, and significant resistance to wear. The equiaxed ferritic-austenitic microstructure guarantees toughness and dependability under harsh conditions, in offshore, marine, and chemical processing applications.
