Esab OK Weartrode 60 T Electrode (OK 84.78)

OK 84.78 is a basic-coated high-alloy hardfacing electrode, providing the best possible wear resistance against abrasive wear. The weld metal is of 4.5% carbon and 33% chromium and has a hardness of 59-63 Rockwell C. Application: OK 84.78 is used for parts particularly exposed to abrasive wear, e.g., parts working in sand, gravel, stone, ore, and coal. Typical applications are excavator teeth, roller paths, mixing arms, transport screws, brickworks equipment, stone drills, etc. The weld metal is corrosion-resistant. OK 84.78 is sometimes used for overlay welding of wear nets on manganese steel when the resistance of manganese steel against crushing wear is desired combined with OK 84.78's resistance to abrasive wear.
