| D708 tungsten carbide surfacing electrode, model: EDW-A-15 surfacing layer hardness HRC ¡Ý65D708 graphite-type coating tungsten carbide surfacing electrode, depending on the coating of tungsten carbide alloy excess, surfacing metal containing tungsten 40% -50% , AC and DC dual-purpose. The welding rod is mainly used for mechanical parts which are subjected to severe wear, such as concrete mixing blades, bulldozers and pump blades, dredger blades, high-speed sand mixing box, brick machine reamer, roller, crusher head, hammer plate, fan impeller, etc. , lining Board, Vertical Kiln Tower Castor, roller press, Cone break and other parts. C 1.50 ~ 3.00 Mn ¡Ü2.00 Si ¡Ü4.00 W 40-50 reference current (AC, DC +) electrode diameter (mm) ¦Õ3.2:70 ~ 120¦Õ4.0:140 ~ 180¦Õ5.0:180 ~ 230D798 tungsten-chromium-boron wear-resistant electrode deposited metal (%) c 1.50 ~ 3.00 Mn ¡Ü2.00 Si ¡Ü4.00 W 40-50 reference current (AC, DC +) electrode diameter (mm) ¦Õ3.2:70 ~ 120¦Õ4.0:140 ~ 180¦Õ5.0 Model: GBEDZCr-D-OO HRC: 66 ~ 68d798 W-CR-B wear-resistant electrode is graphite coating. It works both ways. Slag-free tungsten chromium boron special wear-resistant electrode. There are some alloy elements with fine grain in weld metal, the microstructure of weld metal is fine martensite and a little retained austenite, a large amount of boride and dispersed carbide with HV ¡Ý2800 are distributed on the matrix, the hardness of surfacing layer is high, the wear resistance of high chromium cast iron is 2 ~ 3 times as high as that of common high chromium cast iron, and the hardness remains stable at 600 ¡ã C, high current welding and slag-free, good process performance. The electrode is mainly used for slurry pump, cement equipment and metallurgical equipment to withstand strong abrasive wear occasions.
