【 摘 要 】

The present work deals with the study of microstructure and to examine the effect of sensitization on the corrosion resistance of the Stainless Steel 316 cladding deposited by using SMAW process. Literature explains the susceptibility and resistance of SS316L at ambient temperatures and higher temperatures to examine the corrosion rate of the steel after immersion in the corrosive media. This work reveled that with one layer have less amount of precipitated chromium carbide as compared to the specimen B and C. The result shows that the Austenitic Stainless steel has the best layer thickness to highest corrosion resistance rates. Huey's test gives the microstructure results and through that we have concluded the corrosion rate goes at the maximum value of 2.88 mm by boiling the fresh nitric acid at 67 percentile. By focusing on the future various grades like SS309L, SS304L and materials such as cobalt alloys, copper alloys, manganese alloys, alloy steels, ceramics and composites are employed for weld cladding applications.
