Detailed Photos

For high-temperature environments, the chromium-nickel austenitic stainless steel pipes 309, 309S, and 309H are commonly utilized. These premium grades offer exceptional resistance to oxidation, heat, and corrosion, thanks to their high chromium and nickel content. Moreover, they exhibit superior strength at both ambient and elevated temperatures. The distinction between 309 and 309S stainless steel pipes lies primarily in their carbon content, with 309S having a lower carbon concentration, enhancing weldability and reducing carbide precipitation. On the other hand, the 309H variant boasts a higher carbon content than 309, endowing it with enhanced resistance to creep.

Stainless Steel Welded Tubes

Crafted from top-quality stainless steel strip, our stainless steel tubular products are meticulously roll-formed and fusion-welded along the longitudinal seam. At Daxun, our precise welding process does not employ any filler metal, ensuring a seamless and robust final product.

309 Stainless Steel Tube Features

Outstanding corrosion resistance
Superior resistance to marine atmospheres compared to Alloy 304
Ideal for high-temperature applications, leveraging excellent oxidation resistance
Highly resistant to sulfite liquors
Widely acknowledged as heat-resistant alloys
Destructive scaling temperature is approximately 2000°F^oF
Exceptional scaling resistance for both continuous and intermittent service

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and re-drawing processes to achieve their final size. This method is particularly effective for producing thick-walled, large-diameter tubes that are not feasible to roll directly to size, yet still offer cost benefits over seamless tubes. All our stainless steel drawn tubes are bright annealed for superior quality.
