BAOHUI STEEL produces 347 Stainless Steel UNS S34700, an austenitic chromium-nickel stainless steel stabilized with niobium. This addition prevents chromium carbide precipitation during welding and high-temperature exposure, making it particularly suitable for applications in the sensitization temperature range (425-860°C). Our 347 stainless steel products maintain excellent corrosion resistance and high-temperature strength while offering superior resistance to intergranular corrosion.
