1) If a pronounced yield point occurs, the values for the lower yield point (ReL) apply

2) For thicknesses ≤ 0.7 mm, but > 0.5 mm, minimum values for elongation at break that are 2 units lower are permissible. For thicknesses ≤ 0.5 mm, minimum values 4 units lower are permissible.

3) The minimum values for r90 and n90 only apply to product thicknesses ≥ 0.5 mm.

4) For product thicknesses > 2 mm, the r90 value is reduced by 0.2.

5) Special agreements must be made for thicknesses > 1.2 mm.

6) Vanadium and boron may also be added. The sum of the mass fractions of all four elements must not exceed 0.22%.

* Comparative grade, therefore slight deviations from DIN EN values possible
