Boikanyo Metals is a reputable manufacturer and supplier of Super Duplex Steel Wire, proudly based in Cape Town, South Africa. They specialize in high-quality wire products that are perfect for tough industrial and engineering applications. Super Duplex Steel is known for its remarkable corrosion resistance and impressive mechanical strength, making it a top choice for challenging environments like chemical, marine, and industrial settings. Boikanyo’s Super Duplex Steel Wire is meticulously crafted to meet international standards, ensuring consistent diameter, durability, and dependable performance across various sectors, including offshore, chemical processing, oil and gas, and power generation.
This wire is typically made with high amounts of chromium, nickel, molybdenum, and nitrogen, which give it exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. It boasts a high tensile strength of around 850–950 MPa, excellent fatigue resistance, and maintains its mechanical stability over a wide range of temperatures. The wire’s unique dual-phase microstructure merges the corrosion resistance of austenitic stainless steel with the strength of ferritic stainless steel, making it ideal for high-performance applications like fasteners, springs, and reinforcement components.
