Khaleed Stainless is a reliable manufacturer and supplier of top-quality Stainless Steel 309S Bars based in Riyadh, Saudi Arabia. We provide premium solutions for industries that need exceptional heat and corrosion resistance. SS 309S is a low-carbon version of SS 309, crafted for excellent weldability and minimized carbide precipitation during welding. These bars are perfect for high-temperature environments, boasting remarkable durability, strength, and oxidation resistance up to 1000°C. Manufactured to meet international quality standards, our SS 309S Bars have precise dimensions, a smooth finish, and outstanding mechanical properties, making them ideal for petrochemical, thermal, chemical processing, and power generation applications.
Stainless Steel 309S Bars consist of 22–24% chromium, 12–15% nickel, and ≤0.08% carbon, which ensures excellent oxidation resistance and strength. They also include ≤2% manganese, ≤1.5% silicon, ≤0.045% phosphorus, and ≤0.03% sulfur. These bars have a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. With a Brinell hardness of roughly 217 HB, SS 309S Bars offer remarkable durability and creep resistance. Their low-carbon content enhances weldability, while the austenitic structure guarantees outstanding toughness, even in high-temperature and corrosive settings.
