CRS (Corrosion Resistance Steel) bars manufactured by an addition of Copper and Chromium to prevent from the rust and corrosion. Copper will plug the pores in the rust. By adding Chromium (Cr) into steel, increase the passivity of anions. Another advantage is we are making the steel slightly ferrite thus pitting resistance is increased. Chromium also increases the passivity and will form an invisible layer.

Phosphorous acts as inhibitor. This will reduce the anodic reaction. These CRS bars are manufactured through the TMT procedure.
