Victor Nickelalloys, located in Abuja, Nigeria, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Duplex Steel 2205 Bolts. Renowned for their precision engineering and dependability, this company delivers fastening solutions that cater to the rigorous demands of various industries, including oil & gas, marine, chemical processing, and construction. Their Duplex Steel 2205 Bolts are crafted to provide outstanding strength, durability, and resistance to corrosion, even in the toughest environments. With cutting-edge technology and stringent quality control in place, these bolts guarantee secure, long-lasting performance, making them perfect for applications that require both mechanical strength and exceptional corrosion resistance.
These Duplex Steel 2205 Bolts are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, along with balanced amounts of nitrogen and iron. This distinctive dual-phase microstructure, which combines ferrite and austenite, gives them double the strength of regular austenitic stainless steels. They show remarkable resistance to pitting, crevice, and stress corrosion cracking, especially in environments rich in chlorides. These bolts maintain high toughness and fatigue resistance, even in low temperatures, while also offering good weldability and dimensional stability under heavy loads. Their outstanding mechanical and corrosion-resistant properties make them perfect for critical structural applications.
