From the heart of Kinshasa, Okoye Nickel Alloys stands as a trusted source for high-performance industrial components, specializing in the supply and manufacturing of Duplex Steel 2205 stud bolts. We understand that the demanding conditions of modern industry require materials that offer exceptional resilience. That’s why we provide these robust fasteners, engineered to deliver outstanding strength and corrosion resistance, ensuring the integrity and longevity of your most critical projects right here in the Congo and beyond.
The strength of Duplex Steel 2205 comes from its balanced composition, which nearly equally mixes austenitic and ferritic stainless steel structures. This blend of chromium, nickel, molybdenum, and nitrogen gives the stud bolts a remarkable combination of high tensile and yield strength, far surpassing standard stainless grades. They also inherit excellent toughness and resistance to stress corrosion cracking, making them not just strong, but also incredibly durable against a wide range of chemical attacks.
