This article studies the effect of sulfur on the mechanical properties of cast steels used for shaped castings. It is shown that the sulfur content in steels above 0.023% leads to a sharp decrease in their strength, toughness, ductility, which significantly reduces the operational stability of castings. We made a conclusion about the need to introduce new steel desulfurization technologies in the steel foundry.
