Product Overview
Specialty Pure Iron for Smelting is a premium-grade raw material designed for foundries and steel plants requiring exceptional control over melting efficiency, alloy consistency, and slag reduction. With ultra-low residual elements (S, P ≤ 0.005%) and tailored carbon content, this iron minimizes operational costs while maximizing yield in electric arc furnaces (EAF), induction melters, and vacuum induction melting (VIM) systems.
