SUPRANOX RS 347 is a semi-basic MMA electrode suitable for welding stabilised austenitic stainless steels, AISI 321 and AISI 347. The Nb+Ta in the weld metal is due to the sublimation of titanium at the liquidus temperature of the weld pool. The weld metal mechanical properties are excellent at high temperatures. Outstanding weldability, spatter free and a self-releasing slag, resulting in a very smooth bead appearance. Under wet corrosive conditions, suitable for operating temperatures <400°C, non-scaling <800°C. Efficiency 100%.
