Tabular form :

Rusting, or oxidation, is the most frequent and easily recognizable form of cast iron deterioration. Cast iron is highly susceptible to rusting when the humidity is higher than 65%. Iron (Fe) combines with oxygen (O) in the presence of water vapor (H2O) to become rust (Fe2O3). This process can take place at significantly different rates depending on the material composition, protective treatments applied and severity of exposure. If rusting occurs at a rapid rate, it can result in severe damage or total loss of a component in a short time; therefore, the presence of any rust on a cast iron artifact should alert the observer to the presence of a serious problem. Rusting can occur when the humidity is as low as 58% in the presence of certain pollutants, especially sulfur dioxide, ammonia sulfates or even the presence of body oils from touching. Reducing the humidity to 30% or below has been found to be effective in preventing rusting, however this is not a practical solution for outdoor cast iron.
