Sulfur in steel is considered injurious except when added to enhance machinability. Sulfur readilly combines with iron to form a low melting iron sulphide. Sulfur causes hot shortness in steel unless sufficient manganese is added. Sulfur has a greater affinity for manganese than iron and forms manganese sulphide which has a meltin point above the hot rolling temperature of steel, which eliminates hot shortness. By hot shortness we mean that the steel will literally break apart during hot rolling resulting in a scrapped product

∙ 16y agoThis is a form of solidification cracing during casting operations related to the formation of iron sulfide low melting point consituents. Addition of Manganese decreases this phenomenon by combining with iron and forming more stable manganese sulfides since manganese has a hgher affinity for combining with sulfur than iron does.
