Beschreibung
Zusammenfassung:	A dual phase high strength cold-rolled steel plate, comprising 0.02-0.15 weight % carbon, 1.5-2.5 weight % Mn, less than 0.2 weight % Si, 0.2-1.5 weight % Cr, 0.03-0.15 weight % P, less than 0.06 weight % Al, less than 0.02 weight % S, and the balance iron and unavoidable impurities. The steel according to the present invention permits the low-temperature transformation products to be formed in a greater proportion within a short annealing time to lower the yield ratio and zeroizes the yield point elongation without skin pass rolling. Moreover, the composition is completely free from adverse effects on tensile strength, ductility and galvanizing properties and can provide cold-rolled steel plate suitable for a wide use including motor vehicles.
