Hailing from the heart of Kinshasa, Okoye Nickel Alloys is a dedicated force in the region’s industrial landscape, recognized for supplying robust and reliable materials. We take particular pride in our Duplex Steel S32205 bolts, a product that embodies our commitment to quality and durability. These fasteners are engineered to meet the demanding challenges of modern industry, offering a superior solution where standard components simply fall short. Trust in Okoye Nickel Alloys for materials that are built to perform and endure in the toughest environments.
The strength of our Duplex Steel S32205 bolts comes from a thoughtful blend of elements, primarily chromium, nickel, molybdenum, and nitrogen. This specific composition gives them a unique two-phase microstructure, which results in an impressive combination of high strength and excellent toughness. They offer nearly double the yield strength of common stainless steels, along with outstanding resistance to stress corrosion cracking. This makes them remarkably resilient, able to withstand heavy loads and harsh conditions without succumbing to failure.
