Stainless Steel 409L Pipes are made from ferritic stainless steel alloys that feature a lower carbon content and contain about 10.5–11.7% chromium. This reduced carbon level helps to minimize carbide precipitation, enhancing weldability and resistance to intergranular corrosion. In terms of mechanical properties, these pipes exhibit moderate tensile strength, good ductility, and resistance to oxidation at higher temperatures. They maintain dimensional stability and perform admirably in mildly corrosive and heat-affected environments.
