Cromamig 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 unstabilised grades 304 and 304L. For structural applications at temperatures above 400°C, Cromamig 308H is recommended because of its superior strength at elevated temperatures. The higher silicon content gives better arc stability and weld metal flow, improving bead appearance, particularly when welding dip transfer.
