Resumo
The aim of this work is to assess the influence of cold rolling on the microstructure and pitting
resistance of the NBR ISO 5832-1 austenitic stainless steel. Samples of this stainless steel either with
deformation, corresponding to 30%, 50% and 70% of reduction in thickness induced by cold rolling, or
without deformation (as received), were characterized regarding their microstructure to investigate the
metallurgical effects created during the deformation process. The results showed that certain levels of
cold rolling (30% and 50%) decreased the corrosion resistance of the stainless steel by causing
inclusions fragmentation and voids at the matrix-inclusion interface, whereas unexpectedly, high levels
of cold deformation (70%) resulted in improved localized corrosion resistance. Surface observation
showed that for this level of deformation, the voids created by fragmentation and the matrix-inclusion
interface were shielded with matrix material.
