Atmospheric corrosion behavior of engineering materials, viz., carbon steel, zinc, galvanized steel, and aluminium, has been studied over a period of one year at 41 exposure sites in India using weight-loss methods. Deposition rates of salinity, sulfur dioxide, and climatic variables were determined. Using these data, Indian maps of atmospheric corrosion for carbon steel, zinc, galvanized steel, and aluminum were constructed using pie charts to report results, where the diameter of the pie represents the corrosion rate of the material in each area and the size of the pie portions represent the effect of each variable in the atmospheric corrosion process.
