Inlet Nozzle - Steam Centrifugal Compressor
Inlet Nozzle - Steam Centrifugal Compressor
(OP)
Hi,
I'm trying to figure out the best materials for an inlet nozzle on a steam machine. The steam is superheated, but inevitably some liquid condensates.
The current solution is cast iron with a nickel coating. I see other steam machines using 316L, but I'm having a hard time finding repair history. (The impellers are 17-4PH) 17-4PH has a much harder surface than 316L. If we are using stainless to remove corrosion effects, but also trying to pick a material that will slow down water drop erosion, would 17-4PH be the best solution?
Cheers and thanks,

I am not sure that 1704PH would offer any advantage.
