| 发明名称 | Austenitic alloy pipe and method for producing the same | ||
| 摘要 | There is provided an austenitic alloy pipe that is durable even if a stress distribution different according to usage environment is applied. The austenitic alloy pipe in accordance with the present invention has a tensile yield strength YSLT of at least 689.1 MPa. The tensile yield strength YSLT, a compressive yield strength YSLC in a pipe axial direction, a tensile yield strength YSCT in a pipe circumferential direction of the alloy pipe, and a compressive yield strength YSCC in the pipe circumferential direction satisfy Formulas (1) to (4). 0.90≦YSLC/YSLT≦1.11 (1)0.90≦YSCC/YSCT≦1.11 (2)0.90≦YSCC/YSLT≦1.11 (3)0.90≦YSCT/YSLT≦1.11 (4) | ||
