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.

- Copper content shall be minimum 0.20 %, if copper-containing steel is specified in the purchase order.
- For each reduction of 0.01 percentage point below the specified max C an increase of 0.06 percentage point above the specified max for Mn is permitted up to a max of 1.50% by heat analysis

- Specified elongation value applies to thickness ≥ 4.57 mm. For thickness < 4.57 mm, the minimum elongation value is calculated by the formula : Elongation% = 2.40 d+12"
- Tensile test values apply to "longitudinal" test pieces
