Characteristic
Corten steel (often referred to as Cor–Ten) is a weather
resistant steel grade which could more accurately be termed as an “Atmospheric
Corrosion Resistant Steel”. Weathering means that due to their chemical
compositions COR-TEN A and COR-TEN B steels, when utilised unprotected,
exhibits 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.
Corten steel is a copper chromium alloy steel – this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels. It’s chemical composition promotes the early formation of an adhering protective layer of rust when exposed to the elements.

In order to obtain fine grain structure a sufficient amount
of nitrogen absorbing elements is added (e.g. ≥0.02% Al).
Mechanical Properties
At room temperature for plates ≥3mm in thickness (transverse
test specimans, according to EN 10002). Requirements to hot rolled plates ≤3mm
in thickness according to EN 10025-5.
