Ribbed steel pipes made of Type 2 aluminized steel are commonly used for culverts, which are required to have long service life. However, early corrosion of aluminized steel pipes has been recently observed in some inland locations. Fabrication of sharp bends might cause aluminized coating fissures leading to early corrosion. The extent of brittle failure of the inner, intermetallic aluminized layer as function of simple bending radius was quantified. Electrochemical impedance spectroscopy was used to measure corrosion rate of both formed and flat aluminized steel samples in simulated natural waters. Initial findings show that specimens formed by spherical indentation were susceptible to early corrosion development in moderately aggressive simulated natural water, but less so in a more benign, precipitating simulated natural water solution.
