Victor Nickel Alloys is a well-respected manufacturer and supplier located in Abuja, Nigeria, specializing in top-notch Duplex Steel Coils for a wide range of industrial and marine uses. These coils are celebrated for their remarkable blend of strength, corrosion resistance, and durability, making them perfect for tough environments like chemical processing, oil and gas, and desalination plants. At Victor Nickel Alloys, precision manufacturing and strict adherence to international quality standards are priorities, ensuring that customers receive reliable, high-performance Duplex Steel Coils that cater to various needs both in Nigeria and around the globe.
Duplex Steel Coils typically consist of about 22% chromium, 5–6% nickel, 3% molybdenum, along with trace amounts of nitrogen and other alloying elements. This well-balanced composition delivers impressive tensile strength ranging from 620 to 720 MPa, along with high yield strength and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. The unique duplex microstructure, which includes both ferritic and austenitic phases, provides outstanding toughness, weldability, and long-lasting stability, even under high-pressure and high-temperature conditions.
