Stainless Steel Round Bar 347 is an austenitic chromium-nickel stainless steel known for its excellent corrosion resistance, especially in high-temperature environments. It's stabilized with niobium (columbium) to prevent carbide precipitation, enhancing its weldability and resistance to intergranular corrosion. This material maintains its strength and oxidation resistance up to 1500°F (815°C), making it suitable for demanding applications. Common uses include jet engine parts, high-temperature chemical processing equipment, and boiler components.
