COBALARC 9
 
Preformed Carbides to Resist Abrasion at High Temperatures
Cobalarc 9 is the ultimate in welding technology.
 
It has autogenous fume shielding over preformed carbides in a tubular form, which gives the user genuine low heat input and infinite shelf life by dint of its nonhygroscopic coating.
 
The weld metal consists of complex high temperature carbides, with high-stress abrasion resistance withstanding moderate to heavy impact even at high temperature. The deposit is easily grindable, with good impact property.
 
ALLOY BASE
Fe, C, Cr, Si, Mo, Mn, V
 
SPECIAL FEATURES
  • Exceptional resistance to severe abrasion and moderate to heavy impact at elevated temperature
  • Unmatched deposition rates - high integrity deposits
  • Compared to solid cored electrodes, the current requirement is low so the dilution by parent metal is contained to a minimum
  • Non-hygroscopic coating needs no storage precaution – infinite shelf life
APPLICATIONS
Coal burner nozzles, clinker conveyor chains, railway tampers, sizing screens, augers, agricultural implements, rolling mill guides, heat resistant steel castings, pump casings, I.D. fans, tie rods, pug mill and augers, brick press screws, etc. where high stress abrasion is the major factor of wear at high temperatures.
