CEWELD® E DUR 63 NB is very economical due to its high deposition rate and excellent weldability without slag losses. In the case of critical base material or old hardfacing layers, buffering must be carried out with an electrode such as CEWELD® E DUR 350 Kb / E 11018-G, which provides a weld metal with lower hardness. Overlays on high carbon steel should be buffered with CEWELD®CroNi 29/9 HL or CEWELD® 4370 HL. For best results, 2 to 3 layers should be welded.
- Layer: 57 - 60 HRc
- Layer: 59 - 62 HRc
- Layer: 61 - 65 HRc
For the best results 2 till 3 layers should be welded.
