D608 is a graphite coated CrMo cast iron surfacing welding electrode, which can be used for both AC and DC applications. And it is recommended to adopt DCEP connection method for it
The surfacing metal is Cr and Mo carbides with cast iron structure, so the surfacing layer has good hardness and wear resistance, and has good resistance to the abrasion of sediment and ore.
It applicable for surfacing welding of parts of agricultural machinery, mining equipment and other parts affected by sand wear and slight impact.
