Kolokoltsev V.M., Kotok A.P., Dolbilov K.A. Problem with sulfur in cast steel

Abstract

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.
