Corten Steel Plates COR-TEN A and COR-TEN B

Also referred to as 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 Plates COR-TEN A and COR-TEN B Plates We can supply: 
Thickness from 5mm to 150mm
Width: from 1,500mm to 2,500mm
Length: from 6,000mm to 12,000mm

In order to obtain fine grain structure a sufficient amount of nitrogen absorbing elements is added (e.g. 0.02% Al).
OR-TEN A Plates Mechanical Properties, in the state of delivery condition. 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.
