Corten steel patina

The real name of Corten steel is: steel with improved atmospheric corrosion resistance.
A while ago, we realised that adding copper to mild steel improves its resistance to corrosion.
Other alloy components such as chromium, nickel, phosphorus and aluminium were used to create steel variants that become more resistant to corrosion in certain environments.
Steels with improved atmospheric corrosion resistance are low-alloyed steels, referred to as weathering steels or self-weathering steels – because in certain exposure conditions they are able to cover themselves with a protective coating known as patina.
