Victor Nickel Alloys stands out as a top-notch manufacturer and supplier located in Abuja, Nigeria, with a focus on crafting high-quality Duplex Steel Flanges tailored for industrial, marine, and chemical uses. These flanges are celebrated for their remarkable blend of corrosion resistance and strength, making them perfect for tough environments like seawater piping, offshore platforms, and chemical processing facilities. With a commitment to precision and adherence to international standards, Victor Nickel Alloys ensures that their Duplex Steel Flanges deliver consistent quality, durability, and long-lasting reliability. This dedication to excellence has made their flanges a trusted option for industries not just in Nigeria, but around the globe.
The composition of Duplex Steel Flanges includes about 22% chromium, 5–6% nickel, 3% molybdenum, along with trace amounts of nitrogen and other alloying elements. This unique blend grants them exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, while also providing a tensile strength ranging from 620 to 720 MPa. These flanges are known for their excellent ductility, toughness, and weldability, ensuring they maintain their mechanical integrity even in high-pressure and corrosive settings. Their balanced duplex microstructure contributes to a superior strength-to-weight ratio, ensuring they perform reliably in demanding industrial applications.
