Issues regarding the selection of welding materials for 09MnNiDR

Currently, a new piece of equipment made from 09MnNiDR material is required, which needs post-weld stress relief treatment. This material is being handled for the first time. Welding material manufacturers recommend using electrode model E5518-N5P. The model recommended by NB/T47015-2011 is E5015-C1L, which is equivalent to E5015-N5 per GB/T5117-2012. I would like to ask experienced friends: which model of welding material is more suitable for actual use?

I inquired today, and that’s indeed the situation. If this material is heat-treated for a long period of time, its plasticity will decrease; therefore, welding materials with higher mechanical properties should be chosen, and E5518 has better weldability than E5515.

Manual welding, welding material W607, submerged arc welding H10Mn2A+YD507A
