Beschreibung
Zusammenfassung:	A cold-rolled steel sheet having an excellent press-formability, consisting of less than 0.08 wt. percent carbon, 0.05 to 0.4 wt. percent manganese, 0.015 to 0.10 wt. percent silicon, 0.01 to 0.10 wt. percent acid-soluble aluminum, 0.003 to 0.015 wt. percent nitrogen, the balance being iron and unavoidable impurities, said cold-rolled steel sheet being manufactured through a process step of a continuous annealing with or without an overaging treatment.
