Victor Nickelalloys, a leading manufacturer and supplier located in Abuja, Nigeria, specializes in top-notch Super Duplex Steel Screws that are designed to withstand tough conditions with outstanding corrosion resistance, strength, and durability. These screws are crafted from high-quality super duplex stainless steel, utilizing precise machining and heat treatment techniques to guarantee excellent dimensional accuracy, toughness, and reliability. With their unique dual-phase microstructure, these Super Duplex Steel Screws are renowned for their exceptional resistance to pitting, crevice, and stress corrosion cracking, making them perfect for marine, chemical, oil & gas, and desalination applications where long-lasting performance is a must.
The composition of Super Duplex Steel Screws features a balanced microstructure of austenite and ferrite, with chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and trace amounts of nitrogen. This distinctive blend enhances their strength and corrosion resistance, especially in environments rich in chlorides. They boast a tensile strength of around 800–1000 MPa and a yield strength of about 550 MPa, along with impressive fatigue and impact resistance. Even in low temperatures, these screws maintain excellent mechanical stability and weldability, making them ideal for harsh and corrosive industrial settings.
