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.
However, if the metal atoms are some other metal that corrodes more slowly, like zinc or chromium, then the corrosion can actually be useful, because the oxide coat that forms from the reaction with these metals can prevent the bad type of corrosion. That's why steel is often mixed with other metals, like chromium.
