Boikanyo Sheets and Plates, located in Cape Town, South Africa, has built a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel products, including the Stainless Steel 347 Coil/Slitting Coil. Known for their precision engineering and dependability, Boikanyo guarantees that each coil adheres to strict industry standards, providing outstanding corrosion resistance and durability. Perfect for industrial, commercial, and specialized uses, their 347 stainless steel coils are designed for smooth integration into various manufacturing processes. With a strong focus on quality, timely delivery, and customer satisfaction, Boikanyo Sheets and Plates is the go-to choice for businesses in need of robust, high-performance stainless steel solutions in the area.
The Stainless Steel 347 Coil/Slitting Coil is an austenitic alloy primarily made up of iron, with 17–19% chromium, 9–13% nickel, and 0.5–1.0% niobium, while keeping carbon content low for better stability. This unique blend offers remarkable resistance to intergranular corrosion and high-temperature oxidation. In terms of mechanical properties, it boasts high tensile strength, good elongation, and exceptional toughness, making it ideal for both structural and high-stress applications. The inclusion of niobium helps stabilize the alloy, preventing carbide precipitation during welding or heat exposure, which ensures durability and reliability in challenging industrial settings.
