Most cold rolling coil takes place in multiplepasses and as the size of the Cold Rolled Steel is further reduced, itsstrength and hardness both increase, but its ductility decreases.
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.
The r90 and n90 values apply to product thicknesses ≥ 0.5 mm only.
For thicknesses > 2 mm, the r90-value is reduced by 0.2.
