HARDCOVER 440

< CLICK HERE for additional information on this alloy >

HardCover 440 (HC440) is a tubular,
self-shielded wire for metal arc hardfacing.
It produces a low alloy steel weld deposit for
heavy multi-layer build-up work on carbon
steel parts. HC440 is used for rebuilding
and resurfacing components subject to
metal-metal wear and moderate abrasion.
The weld deposit is machinable.


Typical Applications
• Build-up of earthmoving equipment such as
tractor rollers, idlers, chains and drive
sprockets
• Excavator pads
• Electric shovel track carrier rolls
• Steel shafts
• Gears
• Crane wheels
• Steel mill rolls
• Mine car wheels
• Railcar couplings
