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 compositions of 610MPa high strength steel plate has been successfully developed, that TMCP process and off-line thermal refining process can be adopted to product high strength steel plate for large crude oil storage tanks is suggested.
