A detailed experimental study has been carried out to determine the pitting corrosion of 304 grade steel in acids like hydrochloric acid and nitric acid with different normalities. The corrosion rates have been calculated using weight loss method. In weight loss method without inhibitor, the sample pieces have been weighed and immersed into acids at different normalities like 4N, 5N, 6N, 7N, 8N for different time periods like 48 hours, 76 hours, 92 hours, 120 hours, 144 hours. The study reveals that maximum corrosion rate 0.64 mm/y of hydrochloric acid and 0.625mm/y in nitric acid occurred at the time period of 48 hours and at the normality of 8N. The inhibitor 2-Dimethyl amino ethanol for 8N is also applied to study the efficiency of the inhibitor. The results are also confirmed using the polarisation and FTIR studies.
