Corrosion rates of mild steel when coupled to each of 31 other metals and alloys have been determined in 5 natural environments using disc-type specimens. These environments were industrial, urban/rural and marine atmospheres, natural water and sea water. The relative order of effect on the corrosion rate of mild steel in each environment has been tabulated. The results show that the performance of mild steel in a given couple can differ appreciably in different environments.
