Study of Corrosion Rate of Steel Plates due to Natural Exposure in Corrosive Environments in Tropical Regions

Abstract:

Steel construction is one of the main constructions for building and bridge structures because it has great tensile strength. However the main drawback is its resistance to corrosive environments which makes steel very corrosion prone. So that the use of steel construction must pay attention to the corrosion rate in the environment of use. So we try to do research on the level of corrosion rates in the tropics. This study aims to determine the atmospheric corrosion rate on steel plates in the city of Palu which is in the tropical region and the effect of the angle of installation of the steel plates. In this study there were 27 specimens and each variation of specimens totaled 9 consisting of PL45, PL90 and PL180 plates with a size of 160x80x5 mm. The results showed that the highest corrosion rate occurred in the first month and at an angle of 180⁰ with a corrosion rate value of 2.03 mpy and the lowest corrosion rate occurred in the third month and at an angle of 90⁰ with a corrosion rate value of 1.01 mpy. From this study it can be concluded that the corrosion rate that occurs in Palu City in the tropics is still in the very slow category for all test specimens based on corrosion engineering books.
