Njabulo Stainless is a reliable manufacturer and supplier of Stainless Steel 409 Pipes, proudly based in Cape Town, South Africa. This company focuses on crafting top-notch ferritic stainless steel pipes that are celebrated for their impressive corrosion resistance, heat tolerance, and affordability. The Stainless Steel 409 Pipes from Njabulo Stainless are designed to deliver dependable performance in both automotive and industrial settings. With state-of-the-art manufacturing facilities and rigorous quality control measures, they cater to various sectors, including automotive, construction, heat exchangers, and exhaust systems, providing robust and efficient piping solutions that align with international standards.
These Stainless Steel 409 Pipes are primarily made up of iron, chromium (10.5–11.75%), along with trace amounts of titanium, manganese, silicon, and carbon. The inclusion of titanium helps prevent carbide precipitation, which boosts resistance to intergranular corrosion and enhances weldability. These pipes boast a tensile strength of about 450–550 MPa, a yield strength of around 275 MPa, and commendable ductility. Their ferritic structure ensures excellent oxidation resistance, moderate corrosion protection, and stability at high temperatures, making them perfect for high-temperature exhaust and heat-resistant applications.
