Boikanyo Sheets and Plates, located in Cape Town, South Africa, stands out as a reliable manufacturer and supplier of top-notch steel products, including Duplex Steel Angles. These angles are designed for applications that require exceptional strength, outstanding corrosion resistance, and long-lasting durability. Produced to meet international standards, Boikanyo’s Duplex Steel Angles come in a variety of sizes and thicknesses, making them perfect for structural, marine, and industrial uses. Thanks to their unique dual-phase microstructure, they excel in tough environments, outperforming standard stainless steel in stress corrosion resistance and mechanical stability under extreme conditions.
When it comes to composition, Duplex Steel Angles are made from a balanced blend of austenitic and ferritic stainless steels, typically featuring 20–28% chromium, 4–6% nickel, along with some molybdenum and nitrogen. This alloy configuration provides impressive tensile strength (620–850 MPa) and yield strength (450–650 MPa), all while ensuring good ductility and toughness. Duplex steel is known for its excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Plus, it’s weldable and formable, making it a great choice for fabrication in demanding environments where both strength and corrosion resistance are crucial.
