GEMET 374CW

 

DESCRIPTION :

Specially developed electrode for surfacing crane wheels and for surfacing points and crossings (frogs ) of rails.

CHARACTERISTICS :

The weld metal has fully austenitic structure. The weld metal has increased resistance against friction, corrosion, pressure and shock. The weld metal has very high toughness.

TYPICAL USES :

  • Suitable for cladding on parts subjected to highest pressure and shock load in combination with abrasion. Cladding and built-up can be made on ferritic as well as on hard manganese steel.
  • Crane wheels, cement & mining industry, roller spindles, carrier and wobblers in the steel works, hydraulic press piston etc.
  • For surfacing points and crossings (frogs) of rails.

ALLOY BASIS : Cr, Mo, Mn

ULTIMATE TENSILE STRENGTH OF THE WELD METAL : 850 N/mm2 approx.

HARDNESS OF THE PURE DEPOSIT : Approx. 260 HB

WELDING INSTRUCTIONS :

  • Dry the electrodes at 250°C / 2 hrs.
  • Hold electrode nearly vertical.
  • Welding should be done at low temperature.
  • Interpass temperature should not exceed 150°C.
