A method to manufacture a hot-rolled high-strength steel strip with tensile strength of at least 570 MPa, preferably at least 780 MPa, with an excellent combination of tensile elongation, SFF, and PEF strength, comprising the steps of: • casting a slab, followed by the step of reheating the solidified slab to a temperature between 1050 and 1260 °C; • hot rolling the steel slab with an entry temperature for the final rolling stand between 980 and 1100 °C; • finishing said hot rolling at a finish rolling temperature between 950 and 1080 °C; • cooling the hot-rolled steel strip with a primary cooling rate between 50 to 150 °C/s to an intermediate temperature on the ROT between 600 and 720 °C; • and followed by ∘ mild heating of the steel between 0 and +10 °C/s from latent heat resulting from the austenite-to-ferrite phase transformation, or; ∘ by keeping the steel isothermal, or; ∘ by mild cooling the steel, leading overall to a temperature change rate in the secondary stage of the ROT of -20 to 0 °C/s; • to reach the coiling temperature between 580 and 660 °C; and wherein the steel comprises (in wt%): • between 0.015 and 0.15% C; • at most 0.5% Si; • between 1.0 and 2.0% Mn; • at most 0.06% P; • at most 0.008% S; • at most 0.1% of Al_sol; • at most 0.02% N; • between 0.02 and 0.45% V; • optionally one or more of ∘ at least 0.05 and/or at most 0.7% Mo; ∘ at least 0.15 and/or at most 1.2% Cr; ∘ at least 0.01 and/or at most 0.1% Nb; • optionally Ca in an amount consistent with a calcium treatment for inclusion control; • balance Fe and inevitable impurities; and wherein the steel has a substantially single-phase ferritic microstructure that contains a mixture of polygonal ferrite (PF) and acicular/bainitic ferrite (AF/BF) and wherein the total volume fraction of the sum of said ferrite constituents is at least 95% and said ferrite constituents are strengthened with fine composite carbide and/or carbo-nitride precipitates consisting of V and optionally Mo and/or Nb. • casting a slab, followed by the step of reheating the solidified slab to a temperature between 1050 and 1260 °C; • hot rolling the steel slab with an entry temperature for the final rolling stand between 980 and 1100 °C; • finishing said hot rolling at a finish rolling temperature between 950 and 1080 °C; • cooling the hot-rolled steel strip with a primary cooling rate between 50 to 150 °C/s to an intermediate temperature on the ROT between 600 and 720 °C; • and followed by ∘ mild heating of the steel between 0 and +10 °C/s from latent heat resulting from the austenite-to-ferrite phase transformation, or; ∘ by keeping the steel isothermal, or; ∘ by mild cooling the steel, leading overall to a temperature change rate in the secondary stage of the ROT of -20 to 0 °C/s; ∘ mild heating of the steel between 0 and +10 °C/s from latent heat resulting from the austenite-to-ferrite phase transformation, or; ∘ by keeping the steel isothermal, or; ∘ by mild cooling the steel, leading overall to a temperature change rate in the secondary stage of the ROT of -20 to 0 °C/s; • to reach the coiling temperature between 580 and 660 °C; • between 0.015 and 0.15% C; • at most 0.5% Si; • between 1.0 and 2.0% Mn; • at most 0.06% P; • at most 0.008% S; • at most 0.1% of Al_sol; • at most 0.02% N; • between 0.02 and 0.45% V; • optionally one or more of ∘ at least 0.05 and/or at most 0.7% Mo; ∘ at least 0.15 and/or at most 1.2% Cr; ∘ at least 0.01 and/or at most 0.1% Nb; ∘ at least 0.05 and/or at most 0.7% Mo; ∘ at least 0.15 and/or at most 1.2% Cr; ∘ at least 0.01 and/or at most 0.1% Nb; • optionally Ca in an amount consistent with a calcium treatment for inclusion control; • balance Fe and inevitable impurities; <EOS>
