Product Description

Hard Cover 440 (HC440) is a tubular, self-shielded wire for metal arc hard facing. 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

  • Electric shovel track carrier rolls
  • Steel shafts
  • Gears
  • Crane wheels
  • Steel mill rolls
  • Mine car wheels
