Electrode for Hardfacing

Characteristics and Applications Normally, it can be used in parts surfacing under room temperature and no corrosion condition. As carbon content is high and toughness is poor, basic structure steel is preferred as backing during welding. It is suitable for the parts under conditions of abrasion and impact loading, such as surfacing or repairing welding for bulldozer blades, shovel tooth, hydraulic machinery and mining machinery.
