Research and development is implemented for a 630 MPa strength level high strength-toughness steel plate grade XG630DR according to the present status that the highest strength of 590 MPa for pres-sure vessel plates in normalizing is allowed to use in China.Comprehensive assessment are made for the microstructure properties.In this paper,performance are systematically studied for the plates in normali-zing condition and after SR treatment through microstructure analysis,tensile test,impact test,impact test at different temperature,through thickness test,drop weight test,the SR treatment and welding joint test. The results show that the XG630DR steel has the properties of high strength,good impact toughness,and can be used as the upgrading materials for tanks and tank box.
