FCW TO
Tubular wire for self-shielded metal arc hardfacing
Description & applications
• Tubular wire for self-shielded metal arc hardfacing
• Low alloy steel weld deposit for heavy multi-layer build-up work on carbon steel parts
APPLICATIONS
FCW TO is used for rebuilding and surfacing components subject to metal-metal wear and moderate abrasion. The weld deposit is machinable.
Examples
Build up of earthmoving equipment such as tractor rollers, idlers, chains and drive sprockets, excavator pads, electric shovel track carrier rolls, steel shafts, gears, crane wheels, steel mill rolls, mine car wheels, dredge pins, dredge links, mixer parts, rail car couplings, steel mill roll couplings and any components subject to metal-metal wear.
