Your link refers to Cr and Ni
plated steel. Stainless steel when
alloyed with proper amounts of Cr and/or Ni yields an extremely corrosion resistant metal.
Yes, there are grades of stainless steel that contain less or no Ni, and less Cr, thus are only slightly better than mild steel in normal corrosion testing. I don't know what grades of stainless are used in slides and barrels, but I'm willing to leave that to the metallurgists and engineers that craft the firearms. Suffice to say that blanket statements can not be made w/o knowing the whole of it.
