Hakan Nickel Alloys, based in Istanbul, Turkey, stands out as a top manufacturer and supplier of Duplex Steel 2205 Nuts, crafted for exceptional strength and corrosion resistance in the toughest environments. These high-performance fasteners are specifically designed to meet the demanding needs of industries like offshore oil and gas, petrochemicals, marine, and power generation. By adhering to strict international standards, Hakan Nickel Alloys guarantees precision and durability in every product. Their Duplex 2205 Nuts are known for their remarkable resistance to stress, vibration, and corrosive substances, making them a reliable choice for fastening systems that require longevity and mechanical dependability.
Duplex Steel 2205 Nuts are crafted from a unique dual-phase alloy that includes around 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, resulting in a microstructure of ferrite and austenite. This composition gives them impressive tensile strength (620–880 MPa), outstanding fatigue resistance, and excellent yield strength. These nuts excel in corrosion resistance, particularly against stress corrosion cracking, pitting, and crevice corrosion in environments rich in chlorides and acids. They are non-magnetic, thermally stable, and weldable, ensuring they perform well under varying pressures and temperatures. Duplex 2205 Nuts are perfect for applications that require both mechanical strength and environmental resilience over long service periods.
