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 the unstabilised grades 304 and 304L. The higher silicon content gives better arc stability and weld metal flow which improves bead appearance, particularly when dip transfer welding.
