Because carbon steels are not very highly alloyed, it is not surprising that most grades do not exhibit large differences in atmospheric-corrosion rate. Nevertheless, alloying can make changes in the atmospheric-corrosion rate of carbon steel.
Mixing of metals with other metals or nonmetals can result in alloys that have desirable properties. Steel formed from iron and carbon can vary substantially in hardness depending on the amount of carbon added and the way in which it was processed. Some alloys have a higher resistance to corrosion. Corrosion is a major problem with most metals.
