Hakan Nickel Alloys, a prominent manufacturer and supplier located in Istanbul, Turkey, specializes in high-quality Duplex Tube Fittings that are perfect for industrial applications requiring corrosion resistance and high strength. These fittings are celebrated for their remarkable blend of mechanical strength and resistance to chloride-induced corrosion, ensuring reliable and durable connections even in the toughest environments. Crafted under rigorous quality standards, the Duplex Tube Fittings from Hakan Nickel Alloys promise a long service life, dimensional stability, and outstanding performance, making them a top choice for industries like chemical, petrochemical, marine, oil & gas, and power generation.
Duplex Tube Fittings mainly consist of iron (balance), chromium (19–22%), nickel (4–6%), and molybdenum (2–3%), with trace amounts of nitrogen added to boost strength and corrosion resistance. On the mechanical side, they showcase a tensile strength ranging from 700 to 900 MPa, along with excellent yield strength and impressive fatigue resistance. They maintain toughness, dimensional stability, and reliable mechanical performance across a broad temperature spectrum, including highly corrosive environments rich in chlorides and elevated temperatures, ensuring dependable operation in critical piping systems.
