Boikanyo Fasteners is a reputable manufacturer and supplier of Super Duplex Steel Nuts S32760, proudly based in Cape Town, South Africa. We specialize in providing top-notch fastening solutions tailored for critical industrial and marine applications. Super Duplex Steel S32760 is well-known for its remarkable corrosion resistance and impressive mechanical strength, making it a perfect choice for offshore, chemical, oil and gas, and marine environments. Our S32760 Nuts are meticulously engineered to meet international standards, guaranteeing secure fastening, durability, and dependable performance in even the most demanding industrial systems.
These Super Duplex Steel Nuts S32760 are crafted from an alloy that includes about 25–26% chromium, 6–7% nickel, 4–5% molybdenum, and 0.2–0.3% nitrogen. This unique blend offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, along with a high tensile strength ranging from 850 to 950 MPa. The dual-phase ferritic-austenitic microstructure merges the corrosion resistance of austenitic stainless steel with the strength of ferritic stainless steel, ensuring mechanical stability in both normal and elevated temperatures.
