CSF-71LF

A5.20 E71T-9C/9M

CSF-71LF is a rutile-type flux-cored wire and designed for all-position welding by single-pass & multi-pass with CO2 and Ar/CO2 gas shielding.  It provides excellent usability with stable arc, less spattering, a good bead appearance, better slag removal, and less quantity of welding fume comparable to solid wire.  The wire has 3Y shipping society approval for improved weld deposit impact toughness.

Applications:

Butt, fillet welding of mild steel & 490N/mm2 high tensile strength steels of structure such as bridges, buildings, storage tanks, ships and industrial machinery.
