Stainless Steel 347 Seamless Tubes are stabilized with columbium (niobium), offering excellent resistance to intergranular corrosion and oxidation at high temperatures. The typical composition includes Cr (17–19%), Ni (9–13%), C (≤0.08%), Nb + Ta (10×C–1%), and trace elements of Mn, Si, P, and S. Mechanically, these tubes exhibit a tensile strength of 515 MPa (min), yield strength of 205 MPa (min), and elongation of 40% (min). Their superior creep strength, toughness, and durability make them ideal for high-temperature and pressure applications.

Stainless Steel 347 Seamless Tubes Uses
Applications needing high-temperature strength and superior corrosion resistance frequently use stainless steel 347 seamless tubes. They are perfect for chemical processing equipment, boiler tubes, exhaust manifolds, furnace parts, and heat exchangers. They are appropriate for use in the food processing, power generation, aerospace, and petroleum refining industries because their stabilization with niobium inhibits carbide precipitation. These tubes offer a long service life and dimensional stability while operating dependably in high-pressure systems and oxidizing environments. For crucial thermal and chemical engineering operations, SS 347 seamless tubes are chosen because of their exceptional mechanical qualities and weldability.
