Boudinar,M. Touiker,N. Hammouda and}, keywords = {Corrosion,stainless steel,thermal treatments,soil}, abstract = {In spite of their resistance in many aggressive environments, the stainless steels can be sensitive to some types of corrosion, such as the intergranular corrosion, that can provoke a real disaggregation of the metal due to the selective attack of the spaces between the grains. Following some thermal treatments, a precipitation of chromium carbide carries a local impoverishment in chromium below the necessary content to enssure the protection. To this end, we have studied the effect of the thermal treatments (over-tempering and the income to 600°C) on the electrochemical behavior of an Austenitic Stainless Steel Type AISI 304,with regard to corrosion, in a simulated soil.The metallographic study and the observation in optic microscope realized up on steel in a delivery state, over-tempered and sensitized show that the obtained electrochemical classification allows to deduce that steel in the delivery state is the most resistant.} }
