[MW:31143] Ultimet alloy welding

Dear All,
We are having a FCC unit where "Ultimet alloy-1233" is used in scrubber nozzles. It is observed severely eroded from the internal and external surface. It is presently having a pump volute design with casting.

Request to kindly guide on how to carry out weld build-up/ application of overlay patch on such cobalt rich metallurgy.

It is possible to provide a case hardened material for such high erosive applications? 

Regards,
Devang Majithia
