Impex Tube India, a well-known manufacturer and supplier of Mumbai, India, provides an extensive range of high-quality stainless steel piping and tubing products. One of its specialized products is Stainless Steel 347 Tubing, which boasts superior resistance to intergranular corrosion and exceptional performance in high-temperature service. SS 347 is columbium-stabilized austenitic stainless steel, hence best suited for welding purposes and long-term exposure to high temperatures. Impex Tube India supplies SS 347 tubing to international standards that provide reliable performance in critical industries such as aerospace, power generation, chemical processing, and refineries.
Stainless Steel 347 Tubing is columbium (niobium)-tarnished austenitic stainless steel alloy resistant to precipitation of chromium carbide during welding. Its typical composition is 17–20% chromium, 9–13% nickel, trace columbium and tantalum, and up to a 0.08% carbon content. These components increase its ability to resist intergranular corrosion and oxidation at high temperatures. SS 347 tubing possesses tensile strength of about 515 MPa, yield strength of 205 MPa, and elongation of about 40%. It maintains very good mechanical properties and structural integrity even in cyclic heating conditions and thermal stress.
