| Abstract: | The test for chemical composition,room temperature and 600 ℃ tensile test,impact property,fracture characteristics and hardness testing are implemented in the sampling P92 steel tube operating 16 000 h in ultra-supercritical units of Huaneng Yuhuan Thermal Power Plant.It is shown that the room temperature tensile strength and the specified non-proportionally tensile strength of the steel tube can reach to 703 MPa and 543 MPa respectively.The non-proportionally tensile strength at 600 ℃ high temperature can meet to the specified commands.The impact energy absorbed is more than 160 J and the impact toughness decreases little.The fracture of the impact sample macroscopically characterizes as tough fracture.The precipitated phase is mainly composed by M23C6 carbide,MX phase and Laves phase of Fe2W type. |
