البدائللا يوجد بديل لهذه الورقة.

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 products are supplied in "thermomechanically rolled" condition
  2. This grade is in development progress and orders are subjected to negotiation.
  3. Max carbon equivalent (CE) is increased by 0.01 % for Si ≤ 0.25%, and 0.02 % for Si ≤ 0.04 %
  4. If sufficient nitrogen-binding elements are present, the minimum total aluminium content does not apply.
  5. Carbon equivalent, CEV (IIW) % = C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15

  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 12 mm.
  4. The bending test is carried out only when specified at the time of enquiry and order.
