1. The electrode must be baked at 300~350℃ for 1h before welding. 2. For surfacing welded high-manganese steel workpieces, the fatigue layer should be removed in advance or treated with water toughening or chrome-manganese steel welding rods (such as D277) should be used for bottoming. 3. There is a lot of yellow smoke during surfacing, so attention should be paid to strengthen ventilation and operate from an upwind position. |

| Product description and main application | FK266 is a low-hydrogen potassium type coating high-manganese steel surfacing electrode. It can be used for both AC and DC (when AC welding, the no-load voltage is not less than 70V). It is advisable to use small current and narrow bead when surfacing. Hammer immediately Or water quenching to reduce the tendency of cracks. The surfacing metal is austenitic high manganese steel, which has the characteristics of work hardening, toughness and wear resistance. Since Mo is added to the weld metal, crack resistance and wear resistance are improved; It is suitable for surfacing welding of various crushers, high manganese steel rails, buckets, bulldozers and other parts that are subject to impact and easy to wear. |
