STUDY OF THE IRON MATERIALS CORROSION RESISTANCE IN SOIL CONTAIN SULFUR

Abstract

The corrosion resistance of gray cast iron 3 %C and plain carbon steels (with different carbon contents such as low carbon steel 0.2%C , medium carbon steel 0.45%C , and high carbon steel 0.65%C ) have been studied in soil contain sulfur for 960 hours exposure time . The weight loss technique is used as a function of the corrosion resistance.The results show, that the corrosion rate in a wet soil is larger than that in a dry soil, and the corrosion resistance decreases with the increase of carbon content in the carbon steels. The corrosion rate of gray cast iron resembles to the corrosion rate of 0.2% and 0.45% carbon steels in the same corrosion media.
