Alloy 625 overlay on 316L
Alloy 625 overlay on 316L
(OP)
Anybody have any ideas why there would be a requirement to overlay an existing 316L component with Alloy 625 for corrosion reasons, and have you ever come across this as a weld overlay option?
Thanks
George

Accelerated wastage in this particular type of boiler is due to the chlorides present in the burning plastics.

They are also recommended for tube protection in Biomass boilers.
Babcock Power recommends various alloys and types of overlay for various areas of the boiler

They would probably be better off with a "C" type alloy, but 625 will be compatable.
