FCW B S
Tubular wire for submerged arc hardfacing
Description & applications
• Tubular wire for submerged arc hardfacing
• Low alloy and crack-resistant steel deposit
APPLICATIONS
FCW B S is ideally suited for heavy multi-layer build up work. Weld deposit is machinable.
Examples Build up of all components exposed to metal-metal wear. Components in direct contact with a mating carbon steel or low alloy steel surface.
Ideal for components such as crane wheels, trolley wheels, locomotive wheels, gears, steel shafts, idlers, rollers and any components subject to metal-metal wear.
