In the industrial heart of Kinshasa, Okoye Nickel Alloys has built a reputation as a trusted supplier for demanding applications. We take pride in manufacturing and providing high-performance Duplex Steel 2205 pipe fittings, engineered to meet the rigorous challenges faced by local industries.

The strength of Duplex 2205 comes from its balanced composition of chromium, nickel, molybdenum, and nitrogen. This alloy creates a microstructure that combines the best features of austenitic and ferritic steels. The result is a fitting with exceptional yield strength and superior resistance to stress corrosion cracking, outperforming many standard stainless steels. It also offers excellent toughness, making it a robust choice for high-pressure environments where both durability and corrosion resistance are non-negotiable.
