Abstract：In this study, the cold-rolled Q345 steel specimens were heat treated in different intercritical annealing time and the microstructure and properties were implemented by means of optical microscope and uniaxial tensile test. Through the comparison of the microstructures as well as the tension tests results of steel plates under different holding time, conclusions were drawn that the banded structure eliminated in the holding time of 60-120 s at 790℃and grains had little trend of coursing.
