Effect of deformation and sensitization on corrosion behavior of 304 LN and 316 LN Austenitic stainless steel
Journal Title: International Journal of Experimental Research and Review - Year 2016, Vol 4, Issue 3
Abstract
The present work was concerned with the effect of sensitization and deformation on the corrosion behavior of 304LN and 316LN austenitic stainless steel before and after hot rolling. Specimens were subjected to mechanical deformation and heat treated at 650o C for 5hrs, 6.5 hrs and 8 hrs. Detailed micro-structural analysis using optical metallurgical microscope and hardness testing by Vicker’s hardness tester were carried out to investigate the hardness of the specimens. X-ray Diffraction (XRD) was used to explain the phenomena qualitatively. The electrochemical technique such as the potentiodynamic cyclic polarization measurement was performed to investigate and analyze pitting and protection corrosion resistance properties and also double loop electrochemical potentio-kinetic reactivation measurement technique was also performed for detecting degree of sensitization.
