FIller Metal Breakdown

SC-81M

SC-81M is an all position flux cored wire designed for Ar+20~25% CO2 shielding. You can get smooth arc, and low spatter, good weldability. The weld metal impact values at –60℃(-76℉) is excellent and has good bead appearance, slag covering is uniform and easy to remove.
