Description & applications

•Seamless high fill copper coated tubular wire for semi-automatic gas shielded hardfacing

•Machinable low alloy bainitic deposit
•Unique welder appeal
•Deposition rate increased by up to 20% when compared to solid wire
•Wire does not pick up moisture, the wire feeding properties are excellent
•Designed for welding in horizontal, horizontal-vertical and vertical-up positions
APPLICATIONS
FCW K400 is used for surfacing and rebuilding parts subjected to abrasion, high compressive stresses and impacts.

Examples
Rollers, idlers, chains and drive sprockets, excavator pads, steel shafts, gear teeth, crane wheels, bearing tracks, steel mill rolls, mine car wheels, dredge pins, dredge links, mixer parts, rail car couplings, steel mill roll couplings, cold forging dies and any components subject to metal-metal wear.
