| D608 | According with GB EDZ-A1-08 | ||||||||
| Introduction: D608 is a kind of CrMo cast iron surfacing electrode with graphite type coating. AC/DC. DCRP (Direct Current Reversed Polarity) is more suitable. Because the surfacing metal is Cr and Mo carbide with cast iron structure, the surfacing layer has higher hardness, higher wear-resistance and excellent silt and ore wear-resistance. | |||||||||
| Uses: Used for welding parts of agricultural machinery, mining equipment, etc. which receive grit wear and slight impact. | |||||||||
| Chemical Composition of Deposited Metal (%)
| |||||||||
| Hardness of Surfacing Layer:HRC≥55 | |||||||||
| Reference Current(AC, DC+)
| |||||||||
| Instructions: 1.The electrodes must be baked under about 250℃ for an hour before welding. 2.In surfacing welding, the weldments should be preheated to 400-500℃. If the surfacing thickness permits, a surfacing layer can be made with J507 at first. Then surfacing welding should be done when there is enough heat. The weldments should be cooled slowly after welding. 3.Machine work should not be given to the surfacing layer. It can only be given grinding. | |||||||||
