_{1) XG = dual phase with increased yield strength}

_{2) Reduced minimum values of elongation at break apply to product thicknesses t < 0.60 mm (minus 2 units). * Comparative grade, therefore slight deviations from DIN EN values possible}

_{3) Elongation at break for a proportional sample with L0 = 5.65 √S0 for sheet thicknesses ≥ 3.0 mm}
