Influence of S and Mn on mechanical properties and microstructure of grey cast iron: An overview

Abstract In the present review article, influence of S and Mn on microstructure and mechanical properties is studied. Additionally, effect of manganese and sulfur on the wear property of grey cast iron was also reviewed. The data from different experiments were taken under consideration and studied for the examination of the alloyed cast iron. The study describes that on increasing the manganese content of the grey cast iron, wear coefficient and hardness decreases and impact energy increases. The main motive of addition of manganese is to control the adverse effect of sulfur on the mechanical properties of grey cast iron. Moreover, the presence of manganese counter the formation of FeS, which is the reason for hot shortness in the alloy.
