It's been over 10 years since we had some knock down and drag out discussions over on a knife forum, but as I recall from them hard chrome does a good job on resisting scrapes and such but may be marginal on corrosion, possibly depending on how it's applied.
If chrome is applied by a "physical vapor deposition (PVD)" process, it provides little corrosion barrier, IIRC, though it does improve wear characteristics measurably. I don't know how else chrome may be applied nor whether that makes a difference to corrosion resistance. Apparently, according to those old threads, corrosion continues under the chrome, unseen.
Stainless steel may be problematic in cold weather, according to some internet threads, but I have no opinion as to its truth.
Nickel is great for corrosion resistance.
So, for me, the ideal slide/frame material is carbon steel with nickel coating - my late Nineties Kahr K9.
