Abstract

A high strength hot rolled steel sheet that has a composition which contains in terms of mass% 0.035 0.07% excluding 0.035% C up to 0.3% Si 0.35 0.7% excluding 0.35% Mn up to 0.03% P up to 0.03% S up to 0.1% Al up to 0.01% N and 0.135 0.235% Ti so that the contents of C S N and Ti satisfy the relationship ((Ti (48/14)N (48/32)S)/48)/(C/12)<1.0 (C S N and Ti are the contents of the respective elements (mass%)) with the remainder comprising Fe and incidental impurities and that has a structure comprising both a matrix which comprises a ferrite phase in an areal proportion higher than 95% and titanium carbide which has an average grain diameter less than 10 nm and has finely precipitated in the crystal grains of the ferrite phase. This steel sheet hence has a tensile strength of 780 MPa or higher.
