Stellite Hardface over NiAlBrnz

[BLaroux]

Hello All,

I'm looking for any comments/suggestions/advice on hardfacing Nickel Aluminum Bronze (UNS C95800) with Stellite grade 21. This is in a valve seat application with difficult access to the seating surface.

Does anyone know of this base/filler combo being done before? If its possible, how did it turn out? What process? Is there a stellite grade that might be better suited? Any good references for stellite on copper base welding? (I've found plenty on Fe-base...)

Thanks in advance!
