Blue Demon HardCover HC440 1.2mm 15kg 39HRC Metal on Metal

HardCover 440 (HC440) is a tubular, self-shielded wire for metal on metal hardfacing. Can also be used with C02 Shielding gas. It produces a low alloy steel weld deposit for heavy multi-layer build-up work on carbon steel parts. HC440 is used for re-building and resurfacing components subject to metal on 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 and Rail car wheels Railcar couplings Typical Wire Chemistry (As welded): C/0.15 Mn/1.5 Si/0.8 Cr/1.5 Fe/BAL Welding Current: DCEN Typical Mechanical Properties (As Welded on mild) Hardness on 3 layers Brinell Hardness 360HB HRC 39 Welding Positions: F,H Operating Range - 1.2mm Wire: 120-320 Amps
