Flat / Hot Rolled
Flat steel products are obtained by heating semi-finished products with a rectangular cross-section (slab), which are produced by the continuous casting method, to a specific temperature and then rolling them, with thicknesses ranging from 1.40 to 25.40 mm and widths ranging from 700 to 2025 mm, produceed as coil or by cutting/slit-coiling flat steel products from coils.

- (Nb + V + Ti) ≤ 0.22% and (Mo + Cr) ≤ 0.30 %.
- Max carbon equivalent (CE) is increased by 0.01 % for Si ≤ 0.25%, and 0.02 % for Si ≤ 0.030 %
- If sufficient nitrogen-binding elements are present, the minimum total aluminium content does not apply.
- Carbon equivalent, CEV (IIW) % = C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15
- This grade is produced normalized or equivalent to normalized rolling.
