It’s evaluated the corrosion of 304 stainless steel and steel 1018, embedded in elaborated specimens of concrete on the basis of norms ASTM C470-87 and C192-81. Were elaborated concrete of ration a/c, 0,45 and 0.65 . The specimens were exposed 66 weeks in two aggressive means, solutions to 3,5% of NaCl and 3,5% of Na2SO4. The evaluation was made by the technique of Resistance to the Polarization (Rp), measurement of the corrosion potential (Ecorr) in agreement norm ASTM C-876-91. The results far beyond demonstrate a resistance to the corrosion of steel 304 in both means the one steel 1018.
