Stainless Steel 309 Coil is a high-alloy austenitic stainless steel product designed for use in high-temperature applications. With a higher chromium and nickel content than 304, it provides excellent oxidation resistance and superior strength even at elevated temperatures. This makes it a preferred material in environments where exposure to heat and corrosive elements is common, such as in heat treatment equipment, furnaces, and thermal processing units.
Manufactured through hot or cold rolling processes, Stainless Steel 309 Coils offer outstanding mechanical properties including good tensile strength, excellent formability, and reliable durability. These coils are often supplied in annealed condition to improve ductility and ease of fabrication. They are also available in various finishes and thicknesses to meet the diverse needs of industries such as petrochemical, power generation, and aerospace.
One of the key advantages of 309 stainless steel is its resistance to high-temperature corrosion and scaling. It performs exceptionally well in environments up to 1000°C (1832°F), making it suitable for applications involving continuous or intermittent exposure to heat. Additionally, its resistance to sulfidation and other hot gas corrosion forms makes it ideal for use in exhaust systems, kilns, and chemical processing equipment.
Due to its superior performance and versatility, Stainless Steel 309 Coil is widely used in both structural and engineering applications. Whether you're looking for a reliable solution for high-temperature operations or a corrosion-resistant option for harsh environments, SS 309 offers long-lasting performance and cost-efficiency.
