The inhibitive properties of sodium benzoate for AISI-1018 steel controlling corrosion were studied in seawater environment at atmospheric condition. Three sets of solution were prepared with the concentrations of 0.3M, 0.6M and 1.0M of sodium benzoate respectively. The aim is to enable the rate of corrosion in seawater by using inhibitors. It was found that the highest corrosion rate was observed for the alloy without inhibitor in seawater condition. The corrosion rate is decreases as the concentration of sodium benzoate being increased. These results demonstrate that the higher concentration of sodium benzoate in seawater condition, exhibiting protection of AISI-1018 steel in seawater environment.
