Influence on Pitting Corrosion Resistance of AISI 301LN and 316L Stainless Steels Subjected to Cold-Induced Deformation

Austenitic stainless steels that exhibit good corrosion resistance have recently found increasing applications in industry and transportation. This article addresses the influence of cold rolling deformation on pitting AISI 301LN 316L steels. The results indicate content martensite increases as reduction also increases. current work combined different techniques such optical microscopy scanning electron (SEM) with energy dispersive X-ray spectroscopy (EDS) analyses. Corrosion tests were carried out, accordance ASTM standards. confirm steel performed better than 301LN, regarding corrosion, even when deformed. is due to high molybdenum (Mo) content, which guarantees greater resistance. conducted showed increase reduces overall both It was has higher susceptibility deformation-induced and, despite addition nitrogen, it still a lower performance relative steel. focused evaluating formation pits dynamics microstructures their mechanical properties saline environment including chlorides.
