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.

- Tensile test values apply to "longitudinal" test pieces
- Impact test values apply to "longitudinal" test pieces.
- A50 (%) = 1944 S00.2 / U0.9 (S0: cross-sectional area of the specimen, mm²; U: specified tensile strength, N/mm²)
- 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.
- Measurement of shear area is subjected to negotiation but not guaranteed.
