D999 tungsten carbide wear-resistant covered electrode Hardness of surfacing layer: HRC≥85 Description: The welding electrode is developed with w-cr-b and various wear-resistant alloys as the main raw materials, and can be used for AC and DC. It can be used for coating and welding the worn surface of all carbon steel base materials. The welding layer has super-high hardness and the effect of resisting external impact, and it can bear the strong friction of sand and stones. Usage: It is used for surfacing the mechanical parts which are resistant to strong wear of rocks, such as drilling pairs in brick and tile factories (reamer, stirring cage, counter-rolling, coal and stone crushing, hammer head), stone crusher factories, mining machinery, concrete mixer blades, bulldozer and pump blades, dredger blades, high-speed sand mixing box, etc.
