| Abstract: | This article studies the inclusion features and properties of weather corrosion--resistant hot-rolled 09CuPTiRE plate with different content of rare--earth element and sulphur, The study shows that addi- tion of rare earth element into corrosion resistant steel can obviously change the nature of sulfide and improve the impact toughness at low temperature. Steel has the optimum strength ,yield to strength ratio and low temperature impact toughness with rare earth element to sulphur ratio of RE/S= 1.1. |
