Duplex Steel Tube Fittings are manufactured from a dual-phase stainless steel alloy, combining austenitic and ferritic structures with chromium, nickel, and molybdenum. This composition provides excellent resistance to corrosion, including chloride-induced stress corrosion cracking. Mechanically, they offer high tensile and yield strength, good toughness, and superior fatigue resistance. The dual-phase microstructure ensures stability under high pressure, vibration, and temperature variations, delivering reliable sealing, structural integrity, and long-term durability in demanding piping and tubing applications.
