Low-alloy steels for reinforcing rods in concrete
The corrosion rate of several low-alloy, low-corrosion steels that were developed as candidates for reinforcing rods in concrete, was assessed by the linear polarization (LP) scans and weight loss analysis. The corrosion rate of the reinforcing steel is highly dependent on the passivating oxide film, and the addition of alloying elements forming adherent and stable oxides, can result in a significant improvement in corrosion rate. Small additions of these elements to low carbon steel can decrease the corrosion rate of reinforcing rods significantly. It was observed that if the carbon content and rolling parameters are carefully controlled, the low-alloy steels will have the required physical properties for reinforcing rods. Steels , with low alloying levels and low corrosion rates can be economically advantageous to be used for reinforcing rods in concrete.
