| Abstract: | Based on the traditional C-Mn steel,the Q345GJC high-strength steel plates used for building structures with lower carbon equivalent are successfully developed with the TMCP technology as well as adding microalloys such as Nb and Ti.The main structure of the steel is ferrite,and it is with good impact dutility,welding properties and low yield ratio. |

| Keywords: | TMCP ferrite impact ductility yield ratio |
