OK SELECTRODE 83.40
 
Infinite Fissure-Free Build-up for Impact Loading
A smooth running touch welding low heat input electrode depositing a tough air hardening machinable multi-alloyed weld metal for low stress abrasion and good impact.
 
The deposit is free from surface micro-cracks even for higher build-up. It has high endurance limit and is suitable for compressive and fatigue loading.
 
Special additives in electrode coating make it smooth running and easily maneuverable. Superior bead finish is obtained independent of welder skill.
 
The flux is devoid of hygroscopic elements, making it ideal for site conditions.
 
ALLOY BASE
Fe, Mn, Cr, Ni
 
SPECIAL FEATURES
  • Micro-crack free surface even for higher build-up
  • Very good resistance to metal-to-metal wear and fatigue
  • Smoothest running electrode of its class
  • Low tendency to moisture absorption
  • Marginal work hardening
APPLICATIONS
Hammers, wobblers, railway equalizer beams, crane wheels, excavators, sprockets, rollers, pump shafts, gear teeth, concrete mixer blades, rims, carbon-alloyed rails, dies, striking tools and other machine parts subjected to heavy shock loading and pounding in service.
 
It is the right consumable to use for providing buffer layers where impact and abrasion occur together.
