There is no answer to your enquiry, I have yet to see a blacking process for non-stainless steel which can get anywhere near galvanisation for corrosion resistance.
One of my "Euromillions wish list" projects is a 1R8 in stainless steel with a MoST or similar coating, which is a very dark grey, so there's that :-)
