Structural corrosion of bulk carrier especially of large size and single hull has been a concerned issue for class societies and ship owners worldwide. High tensile steel has been widely used by Asian Shipyard since three decades ago, for the reason of increasing deadweight. Loading with coal or iron ore, the environment in cargo holds is similar to that in porous media. After being applied with stresses of various levels within yield, specimens of AH36 high tensile steel were buried in coal obtained from Indonesia and Australia in laboratory condition. It was found that the average corrosion rates under 95% yield stress were 2.23 mm/yr and 1.59 mm/yr during the first two hours in Indonesia and Australia coal, respectively. The average corrosion rates for specimens under various stresses were ranged from 0.16 mm/yr to 0.26 mm/yr at 10-day period.
