The effects of P content(0.20%~0.39%) on the microstructure,mechanical properties and corrosion resistance of the steel were analyzed by means of scanning electron microscopy(SEM),universal testing machine,impact testing machine,wet-dry composite testing machine and diffractometer.The results show that P content in this study has little effect on the microstructure and mechanical properties of steel.,however,increase of P content will increase the D-type spherical oxide.The increase of P content will reduce the low temperature performance of steel,especially when the temperature is below -40℃.When the content of P in steel is 0.028%,the weathering steel of transmission tower has the best corrosion resistance.The rust layer thickness of indoor accelerated corrosion sample approximates 10 μm.
