Wear-resistant welding rod D618, high chromium wear-resistant alloy welding rod.

Description: D618 is a graphite-coated CrMoW cast iron type surfacing welding electrode, suitable for both AC and DC, with a preference for DC reverse polarity. The surfacing metal consists of Cr, Mo, W carbides in a cast iron structure, giving the surfacing layer high hardness and wear resistance, with excellent resistance to abrasion from sand and ore.
