COR-TEN A applies to plates up to 12.5 mm in thickness, COR-TEN B applies to plates up to 50 mm in thickness.

Weathering means that due to their chemical compositions COR-TEN A and COR-TEN B steels, when utilized 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.

The steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions.
Basic guidelines for the use of this steel in the unprotected condition are described in EN 10025-5 and DASt rule 007.

In order to obtain fine grain structure a sufficient amount of nitrogen absorbing elements is added (e.g. ≥0.02% Al).

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.

In case of cold rolled material the yield point is min. 310 Mpa and the tensile strength min. 445 MPa. Furthermore cold rolled sheets ≤3mm in thickness made of steel grade COR-TEN A-F for increased demand to the cold formability is available.

The notched-bar impact energy is determined on ISO-V longitudinal test specimens at a temperature of - 20°C as an average of three tests. For product thicknesses ≥10mm the average value is at least 27 J. For thicknesses between 10mm and 6mm, the minimum impact value is reduced proportionally to the specimen width (product thickness).

No impact test is performed on products below 6mm in thickness.

Number of Tests
  • 1 tensile test1 test specimen per 40 t from each heat*)Notched bar impact test1 set specimens per 40 t from each heat *)
  • (3 specimens) (at test temperature -20°C)
