Five-Year Field Exposure for Visualized Corrosion of STK400 Graded Steel Pile in Brackish Environment of Phu My Industrial Port (Southern Vietnam)

A long-term field study on corrosion of STK400 steel was established at Phu My port. The large steel pile, which was equivalent to real structures, was placed in all environmental zones to evaluate the overall corrosive effects of the brackish water. After 5 years, the corrosion rate over the entire length of the steel pile was measured and the rust at the boundary altitude between the zones was characterized. The corrosion rate profile shows...
