1) Where a yield strength is defined, the respective values shall apply to the lower yield strength (ReL)

2) For thicknesses ≤ 0.7 mm but > 0.5 mm, the minimum elongation at fracture may be 2 units lower. For thicknesses ≤ 0.5 mm, the minimum elongation at fracture may be 4 units lower.

6) Additions of vanadium and boron are also permissible. The total content of all four elements must not exceed 0.22 % .
