Abstract

A steel sheet having the following chemical composition in mass%: 0.06 0.13% of C 1.2 2.3% of Si 0.6 1.6% of Mn 0.10% or less of P 0.010% or less of S 0.01 0.10% of Al and 0.010% or less of N the remainder comprising Fe and inevitable impurities. The microstructure of the steel sheet includes in volume fraction 90% or more of ferrite having a mean grain size of less than 20 µm and 1.0 10% of perlite having a mean grain size less than 5 µm. A high yield ratio high strength cold rolled steel sheet of excellent elongation and stretch flangeability where the ferrite has a mean Vickers hardness of 130 or higher the yield ratio is 65% or higher and the tensile strength is 590 MPa or greater.
