| Application areas | Steel with improved atmospheric corrosion resistance have a wide range of applications: architecture, smokestacks, freight wagons, silos, pylons and bridges. Since 1 July 2013, the Construction Products Regulation (Regulation (EU) No. 305/2011 – CPR) has required that CE marking be affixed to all products delivered in accordance with a harmonised standard (e.g. EN 10025). This CE marking guarantees, for the uses defined in the standard, the properties described in the declaration of performance submitted by the manufacturer. The corresponding declarations of performance are available on our website at: http://dop.arcelormittal.net/index.php The efficiency of the corrosion protection largely depends on the speed of patina formation. For optimum patina formation: Steel with improved atmospheric corrosion resistance have excellent weldability with all the usual welding processes because of their low carbon content and fine-grained structure | |

| Other | Recommendations for use Attractive appearance of the patina Outdoor use: the patina forms naturally in the open air (over a period of three to four years). Variations in appearance will be observed, depending on the conditions it is exposed to: condensation, evacuation and evaporation of water. After a few years, the patina will stabilise, even in an industrial, sulphur-containing or rural environment. To ensure optimum patina formation, the oxidation process can be accelerated artificially by first descaling the surface (by sandblasting or shotblasting) and then subjecting it to alternate periods of dry and humid conditions. Indoor use: to preserve the natural appearance of the material and at the same time avoid powdery oxide deposits that may cause staining, the following three steps are recommended: Use painted: as the surface has a high reactivity, it is recommended that the first coat of paint be applied on a clean surface immediately after shotblasting or sandblasting.
