Hardfacing Electrodes

THERMEHARD 55

A special type hardfacing electrode depositing Ni-Mo alloy. The weld metal possesses high hardness which is retained even at elevated temperature of 550°C. Ideal for hardfacing components which are subjected to abrasion in combination with impact like blast furnace, belt, hoppers, rolls, tong pins, etc.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 250°C for one hour.

2. Clean the weld area throughly from rust, scale, paint, oil, grease or any other contaminants.

3. Use short arc.
