| Abstract: | The mechanical properties and microstructure of E911 steel tube produced by Germany Vallourec & Mannesmann Company were tested. Aging test and the microstructure observation after aging of E911 steel tube under the delivery condition were performed. The results showed the mechanical properties and elevated temperature tensile properties of E911 steel tube were better than those of T91, and it would be posible to use E911 to replace TP304H, TP321H and TP347H stainless steel tube, solve the weld problem of dissimilar steels and reduce the manufacture cost of boiler. |
