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.

  1. Carbon equivalent, CEV (IIW) % = C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15
  2. If sufficient nitrogen-binding elements are present, the minimum total aluminium content does not apply.
  3. Max carbon equivalent (CE) is increased by 0.01 % for Si ≤ 0.25%, and 0.02 % for Si ≤ 0.030 %
  4. Suitable for galvanizing as "Category B". Category B contains Si 0.14≤ Si ≤0.25%.
  5. This grade is produced normalized or equivalent to normalized rolling.

  1. Tensile test values apply to "transverse" test pieces
  2. Impact test is not carried out for thickness thinner than 6 mm.
  3. Bending test is not carried out for thickness greater than 16 mm.
  4. The bending test is carried out only when specified at the time of enquiry and order.
