Corten Steel (sometimes known as weathered steel) is a group of steel alloys that are often used in outdoor construction.
ASTM Corten A steel plate is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.The steel grade Corten A is according to ASTM standard which with the yield strength of 355MPa and the tensile strength of 470-630MPa.
Corten Steel was designed to eliminate the need for painting and if left outside, exposed to the elements, they will develop a rusted appearance in just a few months.
Corten A steel Chemical Composition Analysis
| Grades | C max | Si | Mn. | P | S max | Cr | Ni | Cu | Nb+V+Ti |
| CortenA | 0.12 | 0.25-0.75 | 0.20-0.50 | 0.07- 0.15 | 0.030 | 0.50-1.25 | 0.65 | 0.25-0.55 | - |
In order to obtain fine grain structure a sufficient amount of nitrogen absorbing elements is added (e.g. ≥0.02% Al)
Corten A steel 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.
| Grade | Permissible yield point ratio | Yield Strength MPa(min) | Tensile Strength MPa | Elongation % (min) |
| Corten A | - | 355 | 470-630 | 20 |
1 Mpa = 1N/mm2 These characteristics are guaranteed in the longitudinal direction; increases by approximately 20 N/mm2 in the transverse direction.
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 for increased demand to the cold formability is available
Corten steel plate, another name is Weather resistant structural steel plate . The anticorrosive properties of weather resistant steel are better than those of other structural steels in many applications. The steel is self-protecting: the rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion.
The corten 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.
