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. The chemical analysis which contains 10-40 ppm boron, is composed according to the customer's request.
  2. Cu + Ni + Cr + Mo ≤ 0.25 %
  3. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total aluminium content of 0.020%.
  4. Al value is the aimed value.
  5. Mechanical test is not carried out.
  6. Suitable for batch annealing after cold reducing.

Flat / Plate

Heavy plate products are obtained by rolling semi-finished products with a rectangular cross-section (slab) produced by the continuous casting method to a specific temperature, with thicknesses ranging from 6.00 to 200.00 mm and widths ranging from 1000 to 3600 mm.
