In this work, a study has been made of the influence of Cr, Ni, and Mo additions on the several concurring mechanical and electrochemical processes, the balance of which determines the cracking susceptibility of austenitic stainless steel (SS). The investigation was conducted in 44% MgCl2 boiling solution. Using the constant strain rate (CSR) method, various criteria allowed evaluation of these effects on mechanical depassivation, localized dissolution, and repassivation. The surface analysis of the passivated metal by glow discharge spectroscopy (GDS) has been used to obtain information on the chemical complex structure and the composition of passive layers formed in this environment.
