Corten steel is up to eight times resistant to atmospheric corrosion compared to unalloyed steels and is characterized by its special alloy elements including copper, nickel, chrome and phosphor.
Enhanced corrosion resistance is based on the oxide layer called "patina" which forms naturally on the steel surface.
Corten is widely preferred in architectural applications for its elegantly brown-orange surface.
MATERIAL DESCRIPTION/MAIN CHARACTERISTICS
Weathering means that due to their chemical compositions COR-TEN A and COR-TEN B steels when utilized unprotected, exhibit increased resistance to atmospheric corrosion compared to unalloyed steels. This is because it forms a protective layer on its surface under the influence of the weather.
The corrosion retarding effect of the protective layer is produced by the nature of its structure components and 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.
The formation, duration of development and protective effect of the covering layer on weathering steels depend largely upon the corrosive character of the atmosphere. Its influence varies and depends mainly upon general weather conditions (e.g. continental) macroclimate (e.g. industrial, urban, maritime or countryside climate) and the orientation of the structure components (e.g. exposed to or shaded from the weather, vertical or horizontal position).
