SS 309S is a low-carbon version of the 309 alloy, designed to minimize carbide precipitation during welding or high-temperature exposure. It offers exceptional oxidation resistance up to 980°C (1800°F) in intermittent service and 925°C (1700°F) in continuous service. The wire form provides excellent ductility and strength, making it ideal for high-temperature applications where corrosion resistance and weldability are critical.
