Khaleed Stainless stands out as a top manufacturer and supplier of Stainless Steel 309S Pipes in Riyadh, Saudi Arabia. These pipes are specifically designed for high-temperature applications where resistance to oxidation and corrosion is crucial. The Stainless Steel 309S variant is a low-carbon version of SS 309, which not only enhances weldability but also retains impressive strength and heat resistance. Perfect for furnace components, exhaust systems, and thermal process equipment, our 309S pipes come in a variety of sizes and specifications. Khaleed Stainless is committed to delivering high-quality products throughout Saudi Arabia and the Middle East, ensuring that you receive reliable performance and timely service.
Stainless Steel 309S Pipes consist of 22–24% chromium, 12–15% nickel, and a maximum carbon content of 0.08%, which boosts weldability and minimizes the risk of carbide precipitation. This alloy excels in resisting oxidation and scaling at temperatures up to 1000°C, boasting a tensile strength of approximately 550–750 MPa. In its annealed state, SS 309S is non-magnetic and provides good toughness and creep resistance. Its lower carbon content makes it ideal for welding and fabrication in heat-intensive settings without sacrificing corrosion resistance.
