At Samia Pipes and Tubes, based in Tunis, Tunisia, we manufacture and supply premium Stainless Steel 309S Tubingdesigned to perform reliably in high-temperature and corrosive environments. Known for its excellent oxidation resistance and durability, 309S tubing is ideal for applications where heat and strength are critical. The low carbon content of the 309S grade improves weldability and reduces the risk of intergranular corrosion, making it suitable for demanding industrial systems. Trusted by industries across Tunisia and beyond, Samia Pipes and Tubes delivers tubing solutions that combine precision engineering, quality, and long-term performance.
Stainless Steel 309S Tubing is an austenitic stainless steel composed primarily of iron, chromium (23–25%), and nickel (12–15%), with low carbon content to enhance corrosion resistance and weldability. It offers excellent tensile strength (typically 515–700 MPa), yield strength (205–310 MPa), and toughness, along with outstanding resistance to oxidation at elevated temperatures. The low carbon level minimizes carbide precipitation during welding and high-temperature exposure. These mechanical properties ensure reliable performance, structural stability, and long service life in applications subjected to extreme heat and corrosive conditions.
