Boikanyo Sheets and Plates, located in Cape Town, South Africa, stands out as a reliable manufacturer and supplier of top-notch metal products, including Duplex Steel Coil and Slitting Coil. Renowned for their exceptional strength, resistance to corrosion, and long-lasting durability, these coils are made to comply with rigorous international standards. Offered in a range of thicknesses and widths, Boikanyo’s Duplex Steel Coils ensure consistent quality and precise dimensions, perfect for all your fabrication and manufacturing needs. Their well-balanced microstructure provides excellent resistance to harsh chemicals and marine environments, making them a go-to choice for industries that demand both high mechanical performance and outstanding corrosion protection.
Duplex Steel Coils are made up of nearly equal parts of austenitic and ferritic stainless steel, typically featuring 20–28% chromium, 4–6% nickel, along with trace amounts of molybdenum and nitrogen to boost corrosion resistance. These coils showcase impressive tensile strengths ranging from 620 to 850 MPa, with yield strengths between 450 and 650 MPa, all while maintaining good ductility and elongation of 20–30%. The alloy is particularly effective at resisting chloride-induced stress corrosion cracking, pitting, and crevice corrosion, making it a superior choice compared to many traditional stainless steels in challenging environments.
