a) A piece of corroded steel plate was found in submerged ocean vessel. It was estimated that the area of plate to be 45 inch ?, and weight loss due to corrosion was 2820 grams. Assuming a corrosion rate of 31 mpy for this steel in seawater, estimate the submersion time in years for this steel plate? Density of steel is 7.9 gr/cm³. b) Recommend two corrective actions to control crevice corrosion.
