Victor Nickelalloys, located in Abuja, Nigeria, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Duplex Steel Screws. Renowned for their precision, durability, and outstanding resistance to corrosion, this company delivers dependable fastening solutions for demanding sectors like oil & gas, marine, chemical processing, and desalination. Their Duplex Steel Screws are designed to excel in tough environments, standing up to seawater, chemicals, and mechanical stress while keeping their structural integrity intact. Crafted with cutting-edge technology and rigorous quality control, these screws promise long-lasting, secure performance, making them perfect for critical industrial and marine applications.
Typically, Duplex Steel Screws are made from Duplex Stainless Steel 2205 or S31803, which includes about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, all balanced with iron. The unique dual-phase microstructure of ferrite and austenite gives them remarkable strength—almost double that of regular austenitic stainless steels—along with excellent resistance to pitting, crevice, and stress corrosion cracking. They boast high tensile and yield strength, impressive fatigue resistance, and stability under mechanical and thermal stress. These features make them ideal for heavy-duty and high-performance fastening tasks.
