Abstract

The inhibition effect of molasses of varying concentrations (0.2g/L, 0.3g/L, 0.4g/L, 0.5g/L) on the corrosion of austenitic stainless steel (type 316L) in 0.5M tetraoxosulphate(vi )acid (H2SO4), Brine (6% NaCl), seawater (3% NaCl) and freshwater media was studied at room temperature. The corrosion rates of the steel were determined using the weight loss method for a period of fifty six days. The solution of the molasses inhibited the corrosion of the stainless steel samples to an extent depending on the concentration of the molasses and the type of medium. The results obtained showed that the higher the concentration of the molasses, the higher the inhibition efficiency (the lower the corrosion rate). The lowest corrosion rates were observed in freshwater medium while H2SO4 acid medium showed the highest corrosion rates. The inhibition is attributed to the physical adsorption of the inhibitor (molasses) on the surface of the stainless steel.
