Stainless Steel 309S Bars

309S stainless steel bars are mainly composed of chromium, nickel, and molybdenum. They also contain some trace elements, such as manganese, silicon, and phosphorus, but in lower concentrations than the other elements. The chemical composition of 309S stainless steel bars may vary depending on the process and grade but is typically 18-20% chromium, 8-12% nickel, and 0.03- 0.08% molybdenum. It also contains a small amount of carbon ( 0.08%), manganese (1%), and sulfur ( 0.030%).

309S SS bars are widely used in various industrial sectors due to their superior properties. Its high-temperature oxidation resistance, heat resistance, and weldability make it the perfect choice for applications like food processing equipment, chemical process vessels, and petrochemical equipment. It also offers good mechanical strength and ductility, making it suitable for structural applications like bridges and buildings. In addition, its corrosion resistance is superior to other stainless steel grades and allows it to perform well in many corrosive environments.
