OK SELECTRODE 84.78
 
Maximum Abrasion Resistance
OK Selectrode 84.78 gives an alloy rich deposit, which offers best resistance to high-pressure abrasion by gritty particles.
 
The stainless bead is temper resistant upto 600°C. The deposit resists corrosion and oxidation even at elevated temperature.
 
Relief cracks, transverse to the weld bead, are desirable.
 
ALLOY BASE
Fe, C, Cr
 
SPECIAL FEATURES
  • Weld bead is convex and dilution is negligible
  • Weld metal is having good corrosion resistance and can withstand high temperatures
  • Smooth arc
APPLICATIONS
Highly recommended for earthmoving, construction, cement and agriculture industries.
 
Road rippers, earth moving parts, excavator blades, crushing mills, edge runners, chutes, mixer blades, screw conveyors, asphalt phasing screws, coal mill exhauster fan blades, plough shares, tampers, scrapers, feeding screws, grader blades, pug mill knife etc.
