Our Stainless Steel 347 Tubes represent a perfect fit to be used in a heat exchanger, boiler, superheater, and chemical processing industries with high probability of continuous exposure to high temperatures and corrosive environments. Presence of columbium prevents intergranular corrosion that occurs during long time heat exposures or welding by stabilizing the material against the formation of chromium carbide.

The tubes maintain high tensile strength and creep levels and therefore can be used as a sure bet solution in critical structure applications in the petroleum, aerospace, marine and power generation industries.Our SS 347 tubes at Hindco Steel And Alloys come in a range of different forms such as seamless, welded and ERW tubes, different lengths and shapes to suit your industrial needs in any customized form. Our raw materials are of the best kind, and we also apply high quality control to make sure that the products fit the needed standards of the ASTM.
