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. Tensile test values apply to "longitudinal" test pieces
  2. The impact test is carried out only when specified at the time of enquiry and order and is not carried out for thickness thinner than 6 mm.
