Bosega Pipes and Tubes is a reliable manufacturer and supplier of Stainless Steel 409L Pipes based in Cape Town, South Africa. They provide top-notch piping solutions that are built to resist corrosion, last long, and remain budget-friendly. Stainless Steel 409L is a low-carbon ferritic stainless steel that excels in resisting high-temperature oxidation and thermal fatigue, making it a perfect fit for automotive exhaust systems and various industrial uses. Bosega takes pride in their precision manufacturing, ensuring smooth surfaces, consistent wall thickness, and compliance with international quality standards, which guarantees dependable performance even in moderately corrosive and high-temperature settings.
The composition of Stainless Steel 409L Pipes includes iron, chromium (around 10–11%), low carbon, and a touch of titanium to boost oxidation resistance and prevent carbide precipitation during welding. These pipes are mechanically sound, offering moderate tensile and yield strength, good ductility, and impressive high-temperature performance. Thanks to their ferritic microstructure, they maintain dimensional stability, resist thermal fatigue, and possess magnetic properties, ensuring they remain reliable for structural and fluid-handling tasks in elevated temperature conditions.
