Iris Pipes and Tubes, based in Cairo, Egypt, stands out as a top manufacturer and supplier of Stainless Steel 309S Pipes. These pipes are celebrated for their remarkable ability to withstand high temperatures, resist oxidation, and endure tough industrial conditions. Crafted from low-carbon austenitic stainless steel enriched with high levels of chromium and nickel, 309S Pipes boast impressive mechanical properties and resist corrosion, even when faced with extreme heat over time. At Iris Pipes and Tubes, cutting-edge manufacturing methods and strict quality control measures ensure that every pipe meets precise dimensions, has a smooth surface finish, and maintains consistent quality. The company caters to the chemical, petrochemical, furnace, and power industries, providing top-notch 309S Pipes for critical applications that demand high performance.
The composition of Stainless Steel 309S Pipes includes 23–25% chromium, 12–15% nickel, along with trace amounts of carbon, manganese, silicon, and iron. This blend results in outstanding mechanical properties, such as a tensile strength ranging from 515–700 MPa and a yield strength between 205–310 MPa, along with excellent ductility, toughness, and resistance to high-temperature corrosion. The low carbon content minimizes the risk of sensitization during welding, ensuring dependable performance in both high-temperature and chemically aggressive settings.
