Abstract

Stainless steels (SS) are. widely used in several fields. In recent years,the good corrosion resistance as well as the remarkable mechanical properties. of SS have made it an even more utilised material. Such extensive utilisation produces new concern about its ability to maintain good properties after many working processes. In this paper an AISI 301 SS with different degrees of cold deformation has been considered. The cold working of these materials produces some important changes in the microstructure (i.e. grain size, crystallographic texture) and involves phase transformations (gamma --> alpha'). Electrochemical measurements have been used to investigate the corrosion behaviour of the alloy in sulphuric acid in the presence of chlorides. In the anodic behaviour of the cold rolled with respect to the annealed SS, a moderate variation of the passivity region but a remarkable increase of the current density was observed. Morphological analyses have been performed to relate the electrochemical results to the alloy structure. The relationship between metallurgical properties and corrosion behaviour has been discussed.
