Hakan Nickel Alloys, located in Istanbul, Turkey, is a trusted name in the manufacturing and supply of Duplex Steel 2205 Bolts, designed for outstanding strength and remarkable resistance to corrosion. These bolts find their place in crucial sectors like oil and gas, petrochemical, marine, and power generation. Hakan Nickel Alloys guarantees that every bolt adheres to rigorous quality and dimensional standards, ensuring dependable performance even in the harshest conditions. Built to withstand stress, vibration, and exposure to aggressive chemicals, Duplex 2205 Bolts from Hakan Nickel Alloys are a reliable fastening choice for applications that demand both durability and longevity.
Duplex Steel 2205 Bolts consist of 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, resulting in a duplex microstructure that balances austenitic and ferritic phases. This unique composition provides impressive mechanical strength, with tensile strength ranging from 620–880 MPa, along with excellent yield strength. These bolts are resistant to stress corrosion cracking, pitting, and crevice corrosion, particularly in environments with chlorides. Their outstanding fatigue resistance and thermal stability make them ideal for high-pressure and high-temperature applications. Additionally, Duplex 2205 Bolts are weldable, non-magnetic, and maintain their mechanical integrity under varying conditions, making them a robust and corrosion-resistant fastening solution for demanding installations.
