For other products, those for the lower yield point (ReL) apply. For thicknesses of ≤ 0.70 mm, but > 0.50 mm, a 20 MPa higher maximum yield point value is permissible. For thicknesses ≤ 0.50 mm, a higher maximum yield point value of 40 MPa is permissible. 2) For thicknesses of ≤ 0.70 mm, but > 0.50 mm, the minimum values for fracture elongation are reduced by 2 units, for thicknesses of ≤ 0.50 mm by 4 units. 3) The r90- and n90- values only apply for product thicknesses of > 0.50 mm. 4) For thickness > 2 mm, the r90-value is reduced by 0.2.

For thicknesses of ≤ 0.70 mm, but > 0.50 mm, a minimum value for fracture elongation of 2 units lower is permissible, and of 4 units lower for thicknesses ≤ 0.50 mm. 2) For thicknesses of ≤ 0.70 mm, but > 0.50 mm, a minimum value for fracture elongation of 2 units lower is permissible, and of 4 units lower for thicknesses ≤ 0.50 mm. 3) The r-values only apply for product thicknesses > 0.50 mm. For thicknesses > 2 mm, the r-value is reduced by 0.2. 4) For thicknesses > 0.50 mm, the yield point may only reach a maximum of 225 N/mm². 5) The steel grades DC03ED and DC04ED are usually decarburized in the solid phase. After decarburization, analysis must only show a maximum carbon content of 0.004 %. 6) If specified by the customer, steel grade DC04EK can be supplied in thicknesses of 0.7 mm to 1.5 mm with Re < 210 N/mm² and A80 > 38 %. It then remains for the manufacturer to select the surface roughness values for a dull matt finish. 19
