Description:
CHT701 is a titania
type flux cored wire to be used with CO2 gas shielding. It makes higher
deposition rate than solid wires and also the welding performance and
mechanical properties of deposited metal are much better than solid wires.
It is suitable for flat or horizontal filler of thick or medial thick mild
steel structures and 490MPa high tensile steel structures such as ships,
machineries, chemical equipments, bridges and vehicles etc.
