Abstract The effects of Ti and Nb micro-alloying elements on the microstructure and properties of low-cost 600 MPa grade ferrite-martensite dual phase steel coiled at low temperature were studied by hot rolling trial-production and compared with the dual phase steel coiled at medium temperature. The results showed that the inter-phase precipitation of nanometer （Nb，Ti）C phase mainly distributed along the grain boundaries， synchronously refined the grain size of ferrite and martensite phases， as well as improved the comprehensive strength and plastic properties of the dual phase steel. Thus， it solved the problem of coarse martensite phase formation that existed in the dual phase steel without the addition of Ti and Nb elements. In addition， the modification of the hot rolling process for dual phase steel coiled at medium temperature was proposed under the consideration of its unfavorable characteristics， such as coarse grain size， less martensite content and slightly low strength property.
