Residuals

Steel

Residuals are elements such as copper and tin, which are usually introduced into the steelmaking process in the form of unsorted or contaminated scrap. This can sometimes, however, impair the physical and mechanical properties of steel. Residuals are key concerns regarding the mini-mills’ recent entry into the flat-rolled market. High residuals can leave sheet steel too brittle for customer use causing problems in the mill.
