GFC 71 (FLUX CORED WIRE)

CLASSIFICATION :AWS/SFA 5.20: E71T-1C, EN 758: T46 0 P C 1 H5 ASME – IIC/SFA-5.20-AWS E 71T-1C

CHARACTERISTICS :

Tubular rutile flux-cored wire for single or multipass welding of carbon, carbon-manganese steels and similar types of steels, including fine grain ones, with CO2 shielding gas. The good weldability in all positions, excellent bead appearance, less spatter, a fast freezing and easy to remove slag. Deposited welds arc of radiographic quality.

TYPICAL APPLICATIONS:

Power Plant equipments, Off-Shore Platforms, Pressure Vessels, Ship building, Railways Wagons, General Fabrication welding, Pipe welding, Bridges, Automobile parts, Tanks etc.
