309/SUH309/309S24 Stainless Coil/Strip
309 stainless steel (UNS S30900) is a high-chromium, high-nickel austenitic heat-resistant stainless steel designed for high-temperature oxidation environments. Compared with 304 stainless steel, it significantly increases the chromium (22-24%) and nickel (12-15%) content, and can maintain excellent oxidation resistance at high temperatures of **continuously 980℃.
