Ni-BASE ALLOY-HIGH CHROMIUM STEEL STRUCTURE AND PROCESS FOR PRODUCING THE NI-BASE ALLOY-HIGH CHROMIUM STEEL STRUCTURE |
摘要 |
There are provided an Ni-based alloy high-chrome steel structure and its manufacturing method capable of joining Ni-based alloys and high-chrome steels by welding, and performing suitable heat treatment, thereby maintaining the strength in the joints. In a manufacturing method of a structure formed by joining together at least two first members formed from Ni-based alloys by welding, and joining a second member formed from high-chrome steels to a member where the first members have been joined together, the manufacturing method includes the steps: joining together the at least two first members formed from Ni-based alloys by welding; performing first-stage aging treatment on a welded joint between the first members, and then, joining the second member formed from high-chrome steels to the member where the first members have been joined together by welding; and then, performing second-stage aging treatment on the welded joint between the first members, and performing heat treatment after welding on a welded portion between the first members and the second member. |
