The surface of a commercial sheet of AISI type 304 stainless steel has been examined by XPS technique in order to determine the effects of its composition of different heat treatments and polishing procedures. Sheet specimens have been solution annealed or sensitised and mechanically polished in water with different SiC papers. The surface respects to be enriched in chromium, to a greater extent in the solution annealed condition, with little influence of polishing conditions. The passive film appears to consist of Fe and Cr oxides and hydroxides, while no Ni has been detected. Chromium appears always in the 3+ oxidation level, while different oxidation levels are present for iron.

Abstract
The surface of a commercial sheet of AISI type 304 stainless steel has been examined by XPS technique in order to determine the effects of its composition of different heat treatments and polishing procedures. Sheet specimens have been solution annealed or sensitised and mechanically polished in water with different SiC papers. The surface respects to be enriched in chromium, to a greater extent in the solution annealed condition, with little influence of polishing conditions. The passive film appears to consist of Fe and Cr oxides and hydroxides, while no Ni has been detected.
