347 Stainless Steel Tubing

We offer 347 stainless steel tubing which is similar to type 321.

Although 347 high temperature SS tubes are similar to 321 in many ways, the addition of tantalum and columbium (niobium) reduces intergranular corrosion at high temperatures. 347 stainless steel tubing is often used in applications requiring repeated heating in the range of 800 - 1650 F (427-899 C) such as expansion joints, high temperature gaskets, aerospace engine parts, exhaust manifolds and chemical production equipment.
