DESCRIPTION
This is a basic coated all position electrode depositing a tough chromium alloy weld metal. This is capable of withstanding high impact and rolling loads with good resistance to mild abrasive and frictional loading.
HARDNESS
26-31 Hrc
APPLICATION
Azucar-HF350R is suitable for rebuilding worn mild steel or low alloy machine parts which require machining after welding. This can also be successfully used as an underlay or buffer between base material and harder overlays (with Azucar 100). Typical components to be welded with this electrode include shafts, mine car wheels, mill pinion, track links, dragline chains, tractor rails, drive sprockets etc.
TECHNIQUE
This electrode is suitable for positional welding and can be multilayered. (Max 4 layers).This can also be hardened to above 480 HV by heating to goo0C and quenching in oil. for mill pinion hard facing old fatigued material have to be removed by grinding before depositing HF35oR
RECOMMENDED AMPERAGE
4.00mm X 350mm – 140 to 180 Amps
Polarity DC t AC 70 OCV min
