Khaleed Stainless is your go-to manufacturer and supplier of Stainless Steel 409L Pipes right here in Riyadh, Saudi Arabia. We pride ourselves on offering top-notch, low-carbon ferritic stainless steel pipes that are perfect for applications where corrosion resistance, weldability, and cost-effectiveness are essential. You’ll often find Stainless Steel 409L pipes in automotive exhaust systems, heat exchangers, and other high-temperature settings. With a variety of sizes and wall thicknesses available, our pipes are designed to meet international standards and cater to customer specifications. At Khaleed Stainless, we’re dedicated to providing durable, high-performance stainless steel products throughout Saudi Arabia and the wider Middle East.
When it comes to composition, Stainless Steel 409L Pipes are mainly made of iron, featuring about 10.5–11.7% chromium and a low carbon content (capped at 0.03%). This lower carbon level enhances weldability and minimizes the risk of intergranular corrosion. Additionally, 409L includes trace amounts of nickel and titanium, which boost corrosion resistance and structural stability. Typically, the tensile strength falls between 380–550 MPa, offering good formability and oxidation resistance even at elevated temperatures. This grade is magnetic and holds its structural integrity during thermal cycling, making it a great fit for exhaust and thermal systems.
