Tanvir Nickel Alloys, located in Cairo, Egypt, stands out as a top manufacturer and supplier of high-quality Super Duplex Steel Stud Bolts. Known for their unwavering dedication to quality and precision, this company caters to a variety of industries that demand high-performance fasteners. These Super Duplex Steel Stud Bolts are specifically designed to endure extreme pressures, high temperatures, and harsh corrosive environments. Thanks to their advanced production methods and rigorous quality control processes, Tanvir Nickel Alloys guarantees that every stud bolt meets international standards. Their expertise and dependable supply chain make them the go-to choice for clients in need of durable, corrosion-resistant, and high-strength fastening solutions for challenging industrial applications.
Typically, Super Duplex Steel Stud Bolts are made up of about 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and a touch of nitrogen, which together provide outstanding corrosion resistance and mechanical strength. These bolts blend the toughness of austenitic steel with the strength of ferritic steel, giving them exceptional resistance to stress corrosion cracking and pitting. On the mechanical side, they boast high tensile strength, often surpassing 850 MPa, and impressive yield strength around 550 MPa. With remarkable elongation and hardness, they maintain their structural integrity even in extreme conditions, making them perfect for critical industrial applications.
