Stainless Steel 321 and 321H Welded Tube is a titanium-stabilized austenitic stainless steel with 17–20% chromium and 9–13% nickel content. The titanium content improves resistance to carbide precipitation when welding. Grade 321H has greater carbon levels than 321, enhancing its creep strength as well as high-temperature performance. These welded tubes usually have tensile strength of 485 MPa, yield strength of 170 MPa, and elongation of approximately 35%. They exhibit superior mechanical strength, weldability, and resistance to oxidation and thus are best suited for continuous use in applications over 800°C.

Stainless Steel 321 and 321H Welded Tubing is commercially used across various industries like aerospace, thermal processing, chemical production, and power generation. Typical applications include exhaust systems, heat exchangers, furnace components, and boiler parts that are subjected to high temperatures. The 321’s titanium stabilization makes it extremely resistant to intergranular corrosion after welding, and the higher carbon content in 321H gives it higher structural strength for heavy duty thermal use. These characteristics make them an economical and dependable choice for long-term service in high-heat and corrosive conditions.
