HARD ALLOY-200
  • Rutile type electrode for hard surfacing of carbon steels, low alloy steels etc.
  • Very stable arc, easily removable slag and smooth weld bead.
  • Performance is excellent on AC as well as DC.
  • Adequate penetration and convex bead ensures ideal weld deposits for surfacing applications to resist high degree of impact and medium abrasion.
  • Hardness: 200-300 BHN (on two-layer deposit).
  • Rolling stock types, Rails, Crank shafts, Oil expeller worms, Gear key-ways, Cog wheels, Rim gear, Wheel rim, Pulleys, Sugarcane rollers.
HARD ALLOY-400
  • Rutile type electrode for hard surfacing of steels subjected to wear due to impact and abrasion. Very stable arc, easily removable slag. Smooth transfer of alloying elements to weld deposit ensures completely crack free and sound weld metal. The weld metal is air-hardening type.
  • Hardness:350-450 BHN (on three-layer deposit).
  • Shovels, Conveyor parts, Gears, Pulverizer rolls, Crawler pads, Punching dies, Forging dies, Plough shears, Shear blades, Gear shafts, Break shoes, Sprockets.
SUPER HARD ALLOY
  • Special electrode with basic type of coating designed for surfacing of parts subjected to heavy abrasion. Very stable & smooth arc which ensures proper alloy transfer to deposited weld. Weld beads are flat and smooth. Slag is easily detachable. Hardness:525-600 BHN (on three-layer deposit).
  • Excavator teeth, Plough shares, Oil expeller worms, Cranes wheels, Cams, Cement die rings.
MODI-Mn
  • Basic coated electrode suitable for reconditioning of austenitic manganese steel parts. Adequate penetration and smooth transfer of alloying elements to weld pool ensures uniform weld metal. Slag is easily removable which leaves bead clean.
  • Weld Hardness:170-220 BHN
  • Work Hardness:400-500 BHN
  • Crusher jaws, Grinding hammers, Railway crossings, Frogs, Dragline bucket teeth, Austenitic manganese steel crossings, Ball mills.
MODI-600
  • Semi-basic coated hard surfacing electrode having good welding properties even on relatively low OCV transformers. Very easy to use and gives smooth weld surface. Resistance to cracking is good. Weld metal shows excellent resistance to tempering upto 500oC.

  • Crusher jaws, Crusher hammers, Farm equipment, Shearing blades, Loading machines, Conveyor buckets, Mixer blades, Cane cutting knives.
MODI-650
  • Basic coated hard surfacing electrode having good welding characteristics even on AC. Highly resistant to cracking and exhibits excellent resistance to tempering upto 500oC.
  • Hardness: 550-650 BHN (on single & multi layer deposit).
  • Cane cutting knives, Bamboo chipper knives, Disintegrater hammers, Oil expeller worms, Crusher jaws, Mine rails, Conveyor buckets, Crane wheels.
MODI - DIEHARD
  • Special purpose hard facing electrode with controlled hydrogen, which gives a deposit of low alloy steel in the weld metal. The weld metal displays excellent resistance to heat and retains hardness at elevated temperatures. The weld metal has high resistance to cracking.
  • Weld Hardness:375-430 BHN (on two-layers).
  • Suitable for surfacing hot forging dies. Repairing of hot working tools.
CARBO - CHROM
