Abstract
The appearance of sulfide inclusions and their position with respect to the grain boundaries in cast 38KhN3MFA and 45 steel are considered as a function of the type of reducing agents employed and the quantities introduced. In the reduction of steel by aluminum, sulfides are seen at the grain boundaries. When using silicocalcium, the sulfides are concentrated within the grains on account of the modifying effect. In selecting the reducing agent, attention must be paid not only to its oxygen affinity but also to its influence on the position of sulfides within the grain.
