SC-71MJ

FIller Metal Breakdown

SC-71MJ

SC-71MJ is a titania-type flux cored wire to be used with Ar-CO2 gas mixture shielding. Provide an exceptionally smooth and stable arc with a fast freezing slag system, this wire is ideal for welding flat, vertical up, vertical down. Bead shape and appearance are excellent in all position welding. It provide excellent notch toughness at low temperature.
