A brief description of wear resistant surfacing electrode and composition table Hardfacing is dissolved in the part surface or edge wear and corrosion, or special properties of deposited metal layer to create two-shape metal parts or repair old parts of metal failure processing method, parts of vulnerable surface is appropriate surfacing could significantly increase their service life. I produced a wear resistant surfacing electrode can be widely according to the requirements of equipment used in agricultural machinery Metallurgy Power mine building vehicles Oil tools die chemical industry equipment. Such as: rolling mill heap to Blade propeller mine bucket roller Turbine Blade various crushing machine high manganese steel rail mill hammer hopper shovel slice the mud pump crusher Hammer blast-furnace bell cone bit dredger leaves Mu Tanji propeller brick machine reamer twisted Polygonum posumbu blender teeth son, cement tray apex shaft sugar cutter knives.
