Corrosion of Embedded MaterialsPCA
The production steps that transform iron ore into steel add energy to the metal. Steel like most metals except gold and platinum is thermodynamically unstable under normal atmospheric conditions and will release energy and revert back to its natural state—iron oxide or rust. This process is called corrosion.

Weathering steelWikipedia
The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words the steel is allowed to rust in order to form the protective coating.
