Gents,
i dont prefere to apply buttering layer, unfortunately my client likes to create stupid problems so, buttering layer means lots of different variables i should check and report,
why i want to use NiCrMo, because it is ready in my stocks. and it will take ages for me to arrange shipment of NiCrFe,
But as far as i understand i have to use NiCrFe,
thank you gents for all answers,
T,
There has been a lot of research in the nuke industry after the Alloy 600 issue. As for a nuke running cooler, it depends on which service in a nuke. After it gets out of containment, it's typically B31.1 anyway. When I see a problem such as the one listed here, I'm going to go with a proven solution every time rather than try to arm chair engineer it.
On the other end of the scale going into to cryo temps, I'd say weld it straight as other issues arise.
As for temps found in a boiler, yeah there are some concerns, and yes it would be the wrong filler.
Regards,
Gerald
