AISI/SUS 309 Stainless Steel Coil/Sheet
Grade 309 is an austenitic stainless steel with high chromium and nickel content, offering excellent oxidation and corrosion resistance at high temperatures. It resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. It is widely used in furnace parts, heating elements, and chemical processing equipment due to its superior heat resistance compared to standard grades like 304.
