Influence of Mn on the Corrosion Behaviour of Medium Manganese Steels in a Simulated Seawater Environment

The influence of Mn on the corrosion behaviour of medium manganese steels was studied by employing a laboratory accelerated corrosion test that involved cyclic wet/dry conditions in a simulated seawater environment. At different time points during the cyclic corrosion tests, the character of the rust film and the susceptibility of the tested medium manganese steels to corrosion were examined using SEM, XRD, and EPMA as well as analysis of the potential-pH diagram. The medium manganese steels
