The Effect of Calcium Treatment on the Corrosion Resistance of Manganese Steels

The metallurgy quality of the steel was improved greatly by calcium treatment which was a technique developed for a long time. The Mn steels treated with calcium, carbon-manganese steels and nickel-chromium steels were collected and their corrosion behaviors were investigated. The results showed that the corrosion resistance of the Mn steel is lower than that of the Ni-Cr steel. The shape of the inclusions can be modified and quality of the steels can be enhanced by the calcium treatment, and the corrosion resistance of the steel treated with calcium is higher than that of the common carbon-Mn steel, and near to that of the NiCr steel.
