FCW CN

Tubular wire for self shielded metal arc hardfacing

Description & applications

• Tubular wire for self shielded metal arc hardfacing

• High chromium cast iron for hardfacing components subject to extremely severe abrasive wear and heavy impact up to 300°C

• The deposit contains hard complex carbides in a tough matrix and performs exceptionally well in both fine and coarse abrasion

APPLICATIONS:

FCW CN is used for hardfacing components undergoing heavy wear by earth, sand or other abrasives. Relief checking is normal.

Examples Sand and earthmoving equipment such as buckets and teeth, railway ballast tampers, dredge buckets and lips, dragline buckets, coke hammers, rippers, sizing screens, crushing equipment, brick industry components, Muller tyres, catalyst lift pipes, pump impellers, fan blades, rockwool rolls, wear plates operating at high temperature in the steelmaking industry.
