Boikanyo Fittings is a reputable manufacturer and supplier of Super Duplex Steel Flanges S32750, located in Cape Town, South Africa. They provide top-notch flanges designed for critical industrial and marine applications. Known for its outstanding corrosion resistance and impressive mechanical strength, Super Duplex Steel S32750 is perfect for use in offshore environments, chemical processing, oil and gas industries, and desalination systems. Boikanyo’s S32750 Flanges are meticulously engineered to meet international standards, guaranteeing leak-proof connections, durability, and dependable performance in even the most demanding piping systems.
These Super Duplex Steel Flanges S32750 are crafted from an alloy that includes about 25% chromium, 7% nickel, 3% molybdenum, and 0.2–0.3% nitrogen. This unique blend offers remarkable 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.
