WELDED JOINT |
| 摘要 |
A welded joint is obtained by using a welding material having a composition: Cr: 15.0 to 30.0%; and Ni: 40.0 to 70.0%, including: a base material having a composition: C: 0.03 to 0.075%; Si: 0.6 to 2.0%; Mn: 0.05 to 2.5%; P: up to 0.04%; S: up to 0.015%; Cr: more than 16.0% and less than 23.0%; Ni: not less than 20.0% and less than 30.0%; Cu: 0.5 to 10.0%; Mo: less than 1%; Al: up to 0.15%; N: 0.005 to 0.20%; O: up to 0.02%; Ca: 0 to 0.1%; REM: 0 to 0.15%; V: not less than 0% and less than 0.5%; and Nb: 0 to 2%, a balance being Fe and impurities and a first-layer weld metal including Fe content from 10 to 40%, all % by mass. |

1. A welded joint obtained by welding using a welding material having a chemical composition including, in mass %, Cr: 15.0 to 35.0%; and Ni: 40.0 to 70.0%, comprising:
a base material having a chemical composition of, in mass %: C: 0.03 to 0.075%; Si: 0.6 to 2.0%; Mn: 0.05 to 2.5%; P: up to 0.04%; S: up to 0.015%; Cr: more than 16.0% and less than 23.0%; Ni: not less than 20.0% and less than 30.0%; Cu: 0.5 to 10.0%; Mo: less than 1%; Al: up to 0.15%; N: 0.005 to 0.20%; O: up to 0.02%; Ca: 0 to 0.1%; REM: 0 to 0.15%; V: not less than 0% and less than 0.5%; and Nb: 0 to 2%, a balance being Fe and impurities; and a first-layer weld metal having a chemical composition including, in mass %, an Fe content ranging from 10 to 40%. |
