JSCC MSW has successfully met the requirements of wire cord for cord applications, particularly in terms of chemical composition and quality. The company used mathematical simulation, based on the methods of non-parametric statistics, to find the optimum response function for high carbon wire rod to show that the rod ductility improves as the total content of Cr, Ni, and Cu grows within the range of 0.15 to 0.45%. MSW uses calcium modified steel made by feeding calcium-containing wire into the ladle-furnace installation in several stages. The use of steel ladles completely made of magnesium materials also contribute to the reduction of steel pollution with exogenous non-metallic inclusions. It was also found that both prestressed concrete wires and reinforcing strands, drawn from JSCC MSW's wire rod that had a central martensite zone up to 90μm long, had excellent processing properties.
