Abstract：The hot-rolled plate met the requirememt of yield strength and elongation by ultra-low carbon,micro-alloying, TMCP (Thermomechanical Controlled Proces), and offline stackingslow cooling of 24 hours without quenching and tempering, making full use of grain refinement and acicular ferrite and granular bainite strengthening. The ultralow-carbon bainitic steel with good toughness and yield strength of 570MPa grade was produced under the same conditions in the industrial production.
