The data set is mainly used to test the tensile properties of 460MPa medium plate of 28mm anti-seismic and corrosion resistant steel produced by Shougang at room temperature. The rolled specimens are subjected to tensile tests at room temperature on a testing machine. The yield strength is 499-501mpa, the tensile strength is 629-630mpa, and the flexural strength ratio is 0.79-0.80. The elongation after fracture is 23.0-23.5%, the strength, yield ratio and plastic properties are good, and the tensile properties meet the requirements of the target.
