Boikanyo Sheets and Plates, located in Cape Town, South Africa, is a trusted manufacturer and supplier of high-quality metal products, specializing in Stainless Steel 409 Coils and Slitting Coils. Known for their excellent corrosion resistance and heat resistance, these coils are ideal for applications in automotive, exhaust systems, and industrial equipment. With a focus on precision and customer satisfaction, Boikanyo Sheets and Plates delivers durable, reliable, and cost-effective solutions that meet the diverse needs of various industries, ensuring exceptional quality in every product.
Stainless Steel 409 Coils and Slitting Coils are primarily composed of chromium (10.5-11.75%) and low levels of carbon, with small amounts of nickel, silicon, and manganese. This composition provides excellent resistance to oxidation and corrosion, especially in mildly corrosive environments. The mechanical properties include a tensile strength of approximately 450 MPa, yield strength around 205 MPa, and elongation of 30%. These coils are highly durable, offering good formability and weldability, making them ideal for applications such as automotive exhaust systems, industrial equipment, and other environments exposed to moderate heat and corrosion.
