HARDFACE B-O

CLASSIFICATION

EN 14700 T Fe1

DESCRIPTION

• Tubular wire for self-shielded metal arc hardfacing

• Low alloys and crack-resistant steel deposit

APPLICATIONS

Hardface B-O 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.
