We've used this material before and cracking can be an issue if you do not properly preheat & slow cool. We mainly used SAW process and we were able to achieve impacts @ -40C.

Hi,
I have used this material for RIG. We can use E111T1-K3MJ for FCAW, E11018M for SMAW, 150 deg.C. Preheat.
Post heat after welding and allow to cool under insulation.
We can achive impact also at -40 deg.C.
