D708 tungsten carbide alloy welding rod Description: D708 tungsten carbide alloy welding rod tungsten carbide transition the surfacing metal containing tungsten, 65% -85%, sophisticated technology off the slag to facilitate stable arc! Preheating before welding electrodes do not need insulation after welding. High hardness, high wear resistance, erosion wear. Good weldability. The anti rock sanding tablets wear, extend equipment life 4-8 times. . Uses: mainly used in chemical equipment and machinery and equipment wear parts surfacing repair. Such as metallurgical machinery, mining machinery, turnouts, jaw, bucket, shovel teeth, engineering brick quarrying ship reamer, spiral mixer blades, fan blades, mineral processing machinery, construction machinery, building materials and machinery! ! Deposited metal chemical composition /% CCrNiSiW ≤ 1.5 ≤ 3.05.0-7.0 ≤ 1.070-85 Surfacing layer hardness: HRC ≥ 70
