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.
Even innovative materials that appear on construction sites can degrade, either by these well-understood mechanisms or through exotic, sometimes surprising, reactions and processes. Steel â Corrosion is the most common and expensive form of material degradation for construction steels, including concrete reinforcement. The U.S. Department of Transportation estimates that the annual direct cost of corrosion in the United States is a staggering $276 billion.
