GFC 719

CLASSIFICATION : AWS/SFA 5.20 : E 71T – 9C Also meets requirements of AWS/SFA 5.20 : E 71T – 12C

CHARACTERISTICS :

Tubular rutile flux-cored wire for single or multipass welding of carbon, carbon-manganese steels and similar grades of steels, including fine grain ones, with CO2 shielding gas. The good weld ability in all positions, excellent bead appearance, less spatter, a fast freezing and easy to remove slag. Deposited weld metal gives excellent impact properties down to minus 30°C
