D256 surfacing electrode, model GB Edmn-a-16 surfacing layer hardness: HB ≥170D256 wear-resistant surfacing electrode, is low hydrogen potassium type coating high manganese steel surfacing electrode, can be AC and DC dual-purpose (AC welding, no-load voltage not less than 70V) , when surfacing should use small current, narrow weld bead, while red hot immediately hammer or water quench, to reduce the crack tendency. The surfacing metal is austenitic high manganese steel, which has the characteristics of working hardening, toughness and wear resistance. Usage: it is suitable for surfacing welding of various impact and abrasion parts such as crusher, high manganese rail, bucket, bulldozer, etc. .
D798 tungsten chromium boron wear-resistant electrode, model: GBEDZCr-D-OO HRC: 66 ~ 68d798 tungsten chromium boron 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 ≥2800 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 ° 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.D608 wear-resistant surfacing electrode, model: EDZ-A1-08 surfacing layer hardness: HRC & GT; 55D608 is a graphite-type coating of CRMO cast iron surfacing electrode, can be used for both AC and DC, more suitable for DC power reverse connection. Because the surfacing metal is Cr and Mo carbide of cast iron structure, the surfacing layer has higher hardness and wear resistance, and has good resistance to wear of sand and ore. Used for agricultural machinery, mining equipment and other parts to withstand sand wear and slight * hit.
D698 wear-resistant surfacing electrode, model: GB EDZ-B2-08 surfacing layer hardness HRC ≥60D698 surfacing electrode is graphite type coating surfacing electrode, AC and DC dual-purpose. It is used for surfacing welding of mineral machinery and strongly worn parts of Earth, sand and stone crushing. The hardfacing layer of high chromium cast iron wear-resistant electrode has high hardness and is composed of granular carbide, martensite and retained austenite, it is suitable for hardening, strengthening and repairing easily worn parts such as suction fan rotor blades, dust pump valves, mud pump impellers, dredgers and so on.
D708 tungsten carbide surfacing electrode, model: EDW-A-15 surfacing layer hardness HRC ≥65D708 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.
