| Application areas | These sheets are particularly suitable for manufacturing complex parts or for improving productivity. | |
| Delivery condtion | These sheets may be delivered from coils produced in the different grades shown below. | |
| Other | Thickness tolerance The consistent thickness and reduced internal stresses 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. Flatness tolerance Two products are available, depending on the level of guarantee required: All the types of guarantee available are summarised in the following table: Dimension tables Cut-to-length sheets will be produced from coils of steels for laser cutting applications and/or from steels in the Amstrong® range. Since the dimensions available are linked to the cutting line, contact our commercial teams for further information on the sheets produced on the line in question. | |
| Surface condition | 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.

| Welding | With the ArcelorMittal steels used to produce these sheets for laser cutting applications, excellent weldability is expected. | |
