The Amstrong® Laser sheet range comprises hot rolled steel grades developed for applications using computer-controlled thermal and mechanical cutting equipment (laser, plasma etc). The sheets are cut to length from ArcelorMittal coils for laser applications on certified lines that are able to reduce internal stresses and improve flatness before, during and after cutting.
All these grades are designed to:
Amstrong® Laser sheets are virtually free of internal stresses and can therefore be used to produce sheets with guaranteed flatness before, during and after cutting.
These sheets are particularly suitable for manufacturing complex parts or for improving productivity.
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:
With the ArcelorMittal steels used to produce these sheets for laser cutting applications, excellent weldability is expected.
These sheets may be delivered from coils produced in the different grades shown below.

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.
The following thickness tolerances (EN 10051:2010) are available: 1/2 or 1/3 for both mill finish and pickled steels.
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:
Laser Classic | Laser Premium | |
---|---|---|
For sheets | Maximum deviation: the minimum value, depending on the circumstances, between 4 mm/m or 8 mm/2 m or 12 mm/3 m and the special tolerances in EN 10051:2010 | Maximum deviation: the minimum value, depending on the circumstances, between 3 mm/m or 6 mm/2 m or 9 mm/3 m and the special tolerances in EN 10051:2010 |
On cut parts | Maximum deviation of 5 mm over a length of 1 m | Maximum deviation of 3 mm over a length of 1 m |
Dimension tables
Cut-to-length sheets will be produced from coils of steels for laser cutting applications (see data sheet A40) and/or from steels in the Amstrong® range (see data sheets A20 – A22). 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.
