A105/LF2 ENP for non-corrosive service

[MaxCarb]

My Client gave me a datasheet of a ball valve, in which an electroless nickel plating surface treatment (min. thk. 50 microns)is required for a standard (non corrosive) service.
I really don't understand the advantages of this choice versus the cost of this treatment (i have 16" valves!!).

Thanks

Your customer didn't provide the working condition?
In my opinion, LF2 is carbon steel, always do phosphitized for rust prevention, maybe the medium can't allow P or something else. So do the nickel coating.
forget it. I think you just need ask the customer for the working condition directly.

The ENP is for wear resistance and improved long term sealing.
