Hmm, 9% seems a bit low. I'd go with the higher percentage of 12% for better corrosion resistance.

I see your point, but I think increasing chromium to 12% would provide better resistance to CO corrosion.

I think the answer is 12%. Chromium is a key alloying element in stainless steel, and it helps increase resistance to corrosion.
