Proweld 347Si MIG

347Si is primarily intended for welding the Nb or Ti stabilised 18% Cr/ 10% Ni austenitic stainless steel grades 347 and 321. It is also suitable for the unstabilised grades 304 and 304L. For structural applications at temperatures above 400°C, 308H is recommended because of its superior strength at elevated temperatures. The higher silicon content gives better arc stability and weld metal flow which improves bead appearance, particularly when dip transfer welding.

Classifications: AWS A5.9 / ER347Si / EN ISO 14343 / G 19 9 Nb Si
