The Atmospheric Corrosion of Structural Steel after Exposure in the Palm Oil Mill Industry Area of Aceh-Indonesia

The major cause of early failure in the infrastructures palm oil industry Aceh, Indonesia has been discovered to be corrosion caused by air pollution from exhaust fumes factory plants. Therefore, this research was conducted analyze effect atmospheric structural steel used mill industry. five types as samples include strip, l-shape, round bar, plate, and SAPH 610 low carbon with a content 0.18%. These specimens were cleansed dirt, scaled, rubbed sandpaper achieve grid 600, later washed fresh water rinsed alcohol, subsequently exposed environment PT ASN AKTS mills for 12 months. Moreover, they placed on measuring tray exposure rate recorded once month using mass loss method line ASTM G50. results showed construction bar shape more resistant remaining also observed safe relatively based their classification being outstanding (< 1 mpy).
