Abstract
The Plain-Carbon steel are considered as one of the most common metallic materials used in engineering and industrial applications due to its ability in altering the micro-structures and mechanical properties as the result of carbon content. These alterations have direct effect on the corrosion rate of steel by building up galvanic corrosion cells between its microscopic phases. The effect of carbon content on the corrosion resistance of Hypo-eutectoid plain carbon steels having different carbon contents such as 0.05%C , 0.2%C , 0.35%C , 0.5%C , and 0.65%C have been studied using three testing durations which are 4 weeks, 6 weeks, and 8 weeks and different corrosion environments such as atmosphere, fresh water, and salt water. The aim of the present work is to obtain the effect of carbon content on the corrosion resistance of steels in different corrosion medium by using the weight loss technique as a function of the corrosion resistance. The results, which have been obtained during this work show that a correlation can be made between corrosion rates and steels carbon content, and the corrosion resistance decreases with the increase in carbon content.
