Based in the industrial heart of Kinshasa, Congo, Okoye Nickel Alloys has built a strong reputation as a trusted partner for critical industrial components. We specialize in supplying high-performance materials designed to meet the demanding conditions of modern industry. Our Duplex Steel 2205 Tube Fittings are a prime example, manufactured to provide exceptional reliability in challenging environments where both strength and corrosion resistance are non-negotiable for operational success and safety.
The strength of Duplex Steel 2205 lies in its balanced composition, which merges austenitic and ferritic steels. It contains chromium, nickel, and molybdenum, alongside a crucial nitrogen addition that significantly boosts its strength. This blend gives the fittings remarkable mechanical properties, including a very high tensile strength and excellent resistance to stress corrosion cracking. They are far tougher than standard stainless steels, offering a perfect balance that handles high pressures and corrosive attacks with ease.
