HARDCOVER 400


Alloy Type:

HardCover 400 (HC400) is a tubular,
self-shielded wire for metal arc hardfacing.
It produces a martensitic weld metal with
good abrasion and impact resistance. This
alloy is especially applicable in applications
of 2-3 layers for wear resistance. HC400
should be considered when good resistance
to abrasion and impact in dry or wet
environments are required.


Typical Applications
• Bucket teeth, lips, undersides and cutting
edges
• Steel mill rolls
• Cable drums
• Sand dredge equipment
• Dragline buckets
• Conveyor chutes
