CLASSIFICATION

EN 14700 T Fe8

DESCRIPTION

• Tubular wire for self-shielded metal arc hardfacing

• Martensitic weld metal with good abrasion and impact resistance

• Self-tempering deposit for hardfacing

• Especially appliable in 2-3 layers for wear resistance

APPLICATIONS

Hardface L-O is used when good resistance to abrasion and impact in dry or wet environments is required.

Examples

Bucket teeth, lips and undersides, cutting edges, steel mill rolls, cable drums, sand dredge equipment, dragline buckets, conveyor chutes, grizzly bars..
