| Abstract: | Based on the low C and Mn elements and the microalloying of Mo, Cu, Cr and Ni elements, the Q460 grade fire- resistant, weather resistant and earthquake resistant structural steel was developed by laboratory smelting and rolling, with the proper process of controlled rolling and controlled cooling. The mechanical properties, fire resistance at high temperature and atmospheric corrosion resistance of the plate were tested and analyzed. The results showed that Q460 steel had excellent toughness and plasticity, low yield strength ratio, good earthquake resistance, fire resistance and weather resistance, and could fully meet the requirements of high- performance structural steel. |
