The mechanical properties and impact properties of different testing steels are tested, and the microstructure and fracture appearance of testing steel are analyzed. According to the experimental results of testing steel, the reasonable chemical compositions of high strength steel plate for large crude oil storage tanks has been proposed. On the basis of the chemical c......
