In this research, the effect of seawater environments and surface roughness on the uniform corrosion rate of carbon steel (A516 grade 65) was studied depending on the experimental work and artificial neural network modeling. The experimental work involves chemical composition, sample machining, roughness measurements (for carbon steel specimens), conductivity and salinity measurements (for seawater), and a uniform corrosion test. The weight loss technique was employed in determining the uniform corrosion rate in carbon steel material. Also, an artificial neural network (ANN) model was built to predict the values of uniform corrosion rate (mpy) at different values of conductivity, salinity for seawater and roughness factor for carbon steel depending on the experimental results which were used to train and test the ANN. The results obtained of uniform corrosion rate by ANN predictions are shown to be agreed well against experimental values. i.e. correlation coefficient, R=0.9974
