Stainless Tig Rods
ER347 has columbium added to it’s composition as a stabilizer. The addition of columbium reduces the possibility of intergranular chromium carbide precipitation and thus susceptibility to intergranular corrosion.
Tantalum and columbium are both good at stabilizing carbon and in providing high-temperature strength. Typical applications include welding, repairing and overlaying of stabilized grades of stainless steel, like type ER347 and type ER321.
ER347 is used in the refinery industry to combat high-temperature erosion corrosion and fatigue. ER347 is normally used to weld AISI 321 since titanium will not transfer across the arc.
