| Application areas | This grade is particularly suitable for manufacturing complex parts or for improving productivity when parts are to be produced on a small scale. 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. | |
| Coating | Galvanisation: Class 1 | |
| Other | Steel coils supplied for laser cutting are virtually free of internal stresses and can therefore be used to produce sheets with guaranteed flatness before, during and after cutting, provided that appropriate decoiling tools and procedures are used. Sheets produced on cutting-to-length lines certified by ArcelorMittal may have guaranteed flatness before, during and after cutting. For thicknesses below 16 mm, steels for laser cutting offer significantly higher laser cutting speeds than those obtained with standard grades and/or conventional cutting processes (plasma, oxy-cutting). These steels can be hot dip galvanised. Laser cutting speed largely depends on surface homogeneity and reflectivity. To improve productivity for our clients, ArcelorMittal has developed several surface finishes compatible with laser cutting: Mill finish: Pickled: ArcelorMittal's hydrochloric acid pickling process produces a clean, more favourable surface for laser cutting than that produced by sulphuric acid pickling.
Thickness tolerance The consistent thickness and reduced internal stresses of these coils make it possible to operate laser cutting machines continuously by lowering the breakdown risk and the frequency of laser cutting head breakage. This allows the use of fully automated loading and discharging systems. The following thickness tolerances (EN 10051:2010) are available: 3/4, 1/2 and 1/3 for both mill finish and pickled steels. Contact our commercial teams for stricter tolerances. Amstrong® grades are delivered with a thickness tolerance of 1/2 EN if a tighter tolerance is not requested. Flatness tolerance Since the degree of sheet flatness obtained mainly depends on the uncoiling and levelling process used during laser cutting, we cannot offer any guarantee for coil products supplied. | |
| Welding | Due to their low carbon equivalent value, ArcelorMittal's steel coils for laser cutting applications offer excellent weldability. | |
