Description:
Cromacore DW 347 is a rutile flux cored wire for welding the Nb or Ti stabilised stainless steel grades
347 and 321. It is also suitable for the unstabilised grades 304 and 304L. For welding the controlled
carbon material grades 321H and 347 H, used for structural applications at temperatures above
400°C, Cromacore DW 308H is recommended because of its superior creep strength. The wire is
mainly used for the horizontal and horizontal-vertical positions.
Cromacore DW 347 is BIsmuth free (<0,002 wt%).
