ASTM A312 / A213 / A269 / A358 / A249 TP347 Stainless Steel Pipes & Tubes

We provide a comprehensive selection of Stainless Steel Pipes to customers across the industry. We specialize in the production and provide these stainless steel pipes in a variety of sizes, including standard and nonstandard sizes, as well as varied radiuses and diameters. We also provide our customers with stock supply of Stainless Steel 347 Pipes in a variety of standard sizes and types.

It is made of austenitic stainless steel, but it also contains columbium, which makes it a form of austenitic stainless steel that is often used. And we manufactured these stainless steel pipes, which are the most often utilized in high-temperature applications. We are able to provide these Pipes with exceptional forming and welding characteristics. In addition, the inclusion of columbium and tantalum in the composition contributes to the material's remarkable intergranular corrosion resistance.
