EN 10025-2 Grade S240 Laser
EN 10025-2 Grade S240 Laser introduction
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:
Give improved productivity, quality and consistency with laser cutting
Meet the most stringent flatness requirements after cutting
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.
Equivalent material: EN S235JR, EN EN S235JRJ0
