Hakan Nickel Alloys, based in Istanbul, Turkey, specializes in crafting and supplying Duplex Steel 2205 Tubing, which is celebrated for its remarkable strength and outstanding resistance to corrosion. The company caters to vital sectors like offshore, petrochemical, and chemical processing, providing tubing solutions that adhere to rigorous international standards. With a commitment to durability, precision, and performance, Hakan Nickel Alloys guarantees that their Duplex 2205 Tubing performs reliably in harsh, corrosive, or high-pressure environments. This tubing is perfect for situations where traditional stainless steel might falter, offering a longer service life and cost-effectiveness in tough operational conditions.
Duplex Steel 2205 Tubing consists of about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, resulting in a duplex microstructure that balances austenite and ferrite. This unique structure gives it impressive mechanical properties, including a tensile strength ranging from 620 to 880 MPa and a high yield strength. The alloy is particularly resistant to stress corrosion cracking, pitting, and crevice corrosion, especially in environments rich in chlorides or acids. It also holds up well under high temperatures and pressures. The tubing is weldable, tough, and fatigue-resistant, making it an excellent choice for demanding industrial applications that require both high mechanical strength and corrosion resistance.
