D708 tungsten carbide rod 
 Description: D708 tungsten carbide surfacing electrode with the transition metal tungsten carbide 65% -85%, sophisticated technology to facilitate stable arc slag off! Electrode does not require preheating before welding, after welding heat. High hardness, high wear resistance, erosion and wear. Good solderability. Abrasive sanding against the rock, extend equipment life 4-8 times. . 
 Uses: mainly used in chemical equipment and machinery and equipment welding repair worn parts. Such as metallurgical machinery, mine machinery, turnout, jaw plate, bucket, shovel teeth, works such as quarrying, brick cutter ship, screw, mixer blades, fan blades, mineral processing machinery, engineering machinery, building materials and machinery! !
