Al is correct. Reversing the procedure will strip the chrome. Nickel can only be stripped with acid, and if done by a uncompetent shop, can lead to a disaster to the steel.
When I have nickel stripped, I pay to have an employee of the company tending the stripping from start to finish. The cost is $200. I've replated a dozen or so of K-80s, and when they've been stripped, it's been only the nickel.
Talk to Whiz White about stripping nickel at a shop where they bath the parts in acid and walk away, not a pretty sight.
Stay away from CraftGuard in Des Moines, IA. They did a pretty good job trying to ruin a brand new Perazzi MX14.
I also have my 27 yard Perazzi in satin chrome. I would never do satin nickle again, only the chrome, if I have a choice. I had satin chrome done by A&A Engraving right here in Rapid City SD.
A&A is the company who does most of the commemoratives you see in the NRA magazines. Very professional, but now VERY busy. The owner, Mark Armstrong, did mine for nothing as a friend thing - he is a superb artist in gun-craft and has built one helluva business doing the same. I'd never impose upon him again, but his work was absolutely outstanding and 100% above any expectations I had.
