Hakan Nickel Alloys, based in Istanbul, Turkey, is a trusted name when it comes to manufacturing and supplying high-performance Duplex Steel 2205 Fasteners. These fasteners are specifically designed to thrive in corrosive and high-stress environments, making them a go-to choice in industries like marine, oil and gas, chemical, and power. With a strong focus on quality and durability, Hakan Nickel Alloys ensures that their fasteners meet international standards for strength and resistance to corrosion. Duplex 2205 Fasteners excel in tough conditions, making them ideal for securing critical components in systems that face aggressive fluids, pressure changes, temperature swings, and mechanical stress.
When it comes to composition, Duplex Steel 2205 Fasteners are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, which creates a well-balanced austenitic-ferritic microstructure. This unique dual-phase structure provides the fasteners with impressive tensile strength (620–880 MPa), high yield strength, and outstanding fatigue resistance. They are particularly resistant to pitting, crevice corrosion, and stress corrosion cracking, especially in environments rich in chlorides or acids. Plus, they maintain their mechanical properties even at elevated temperatures and under dynamic loads. Their excellent weldability and dimensional stability make Duplex 2205 Fasteners perfect for long-term use in critical, high-performance bolted connections.
