Beschreibung
Zusammenfassung:	The cold-rolled steel plate has a chemical composition containing C from 0.03 to 0.12%, Si from 0 to 1.0% (including a case where Si is not added), Mn from 0.2 to 0.8%, P at 0.03% or less (excluding a case where P is not added), S at 0.03% or less (excluding a case where S is not added), Ti from 0.04 to 0.3%, and Al at 0.05% or less (excluding a case where Al is not added). A residue is formed of Fe and unavoidable impurities. Each element satisfies a relationship of 5C %−Si %+Mn %−1.5Al %
