The mechanical properties are tested transverse to the direction of rolling.

1) A80 value applies for thicknesses < 3.00 mm.

2) A5 value applies for thicknesses ≥ 3.00 mm.

3) The bending guarantee is valid for both longitudinal and transverse direction.

All SSAB Laser® steels are aluminum-killed (Al ≥ 0.015%) and grain-refined. Additionally, niobium (Nb), vanadium (V), titanium (Ti) and/or boron (B) may be used as single alloying element or in any combination.

Tolerances

All SSAB Laser® products are delivered with SSAB Laser® tolerances, which means increased guarantees compared to corresponding EN standards. Detailed information is available on ssab.com.

Thickness

Hot rolled sheet: SSAB Laser® tolerances correspond to 2/3 of EN 10051 as default. Tighter tolerances are available upon request.

Hot rolled plate: SSAB Laser® tolerances correspond to 3/4 of EN 10029 as default.

Width

Hot rolled sheet: -0/+20 mm for mill edge sheet; -0/+2 mm for cut edge sheet. Tighter tolerances are available upon request.

Hot rolled plate: -0/+4-10mm depending on the thickness.
