SUS 347 Pipes & Tubes

SUS 347 is a grade of stainless steel that offers excellent corrosion resistance, high temperature strength, and exceptional mechanical properties. The "SUS" designation indicates that it is part of the Japanese stainless steel standard, with "347" specifying its specific composition. SUS 347 pipes and tubes are widely used in various industries, including chemical processing, petrochemical, pharmaceuticals, and aerospace, due to their superior performance in corrosive environments. The alloy's main components include chromium, nickel, and columbium, which contribute to its resistance against intergranular corrosion and sensitization during prolonged exposure to elevated temperatures.

These pipes and tubes are ideal for applications involving high temperatures, such as in heat exchangers, furnace components, and radiant tubes. The addition of columbium helps prevent chromium carbide precipitation, ensuring sustained corrosion resistance even after welding or other thermal processes. The seamless and welded SUS 347 pipes and tubes are available in various sizes and dimensions to meet diverse industrial requirements. Their versatility extends to applications in oil and gas refineries, where they are employed for conveying corrosive fluids, and in the manufacturing of chemical processing equipment. In summary, SUS 347 pipes and tubes are a reliable choice for industries demanding robust corrosion resistance and high-temperature performance, making them an essential component in critical applications across different sectors.
