I need some advice. We will be welding with Manaurite 45/35 and 35/25. Does anyone know anything about this? Like a what P number, F number, grade, SA or SB #, etc.... We will be welding furnace tubes and no PWHT.
Looking at the job scope it states that we will be welding with it on some furnace tubes. So I am taking it that this is the rod we will be using???? I'm not sure. I'm going to pull the folder and see if I can't find more info on the scope of work.
OK it says that we are to connect the 20cr 32ni materials using Manaurite (35cr-45ni) and for a different weld use Manaurite (25cr-35ni) filler metals. I found a Manaurite XM and XTM But no other information other than that.
It also says on the drawing 35cr-45ni+nb+micro XTM or equal..... If that is any help.
