D208 Wear-Resistant Flux-Cored Wire is primarily used for surface overlay welding repair of worn medium and low carbon steels and alloy steels. It belongs to the lime-titania type overlay welding wire, offering stable arc during welding, easy slag removal, and excellent forming results. The hardness of D208 welding wire ranges from HRC 54-57, making it suitable for surface overlay welding on various worn mechanical components, with good crack resistance and machinability.
Specific application areas of D208 Wear-Resistant Flux-Cored Wire include:

Grinding Rolls and Grinding Discs: Used for repairing and strengthening grinding rolls and discs to enhance their wear resistance.
Hopper Liners, Hammer Heads and Hammer Discs, Bucket Teeth, Jaw Plates, Grate Teeth, Mixer Blades, Rollers, Chute Liners, Single-Tooth Rollers, Grate Plates, Impellers, Propeller Tooth Plates, Chutes, Hoppers, Brick Machine Augers, Liners, Buckets, Wheel Buckets, Shovel Teeth, Coal Mill Roller Sleeves and Grinding Discs, Chute Liners, etc.: These components are frequently subjected to wear, and using D208 welding wire can effectively extend their service life.
Additionally, during overlay welding, D208 welding wire requires the use of direct current reverse polarity (DC+) to ensure optimal welding results.
