| 摘要 |
Provided is a precipitation hardened Fe—Ni alloy having the following constitutions: (1) the precipitation hardened Fe—Ni alloy including: from 0.01 to 0.08% by mass of C, from 0.02 to 1.0% by mass of Si, not more than 1.0% by mass of Mn, from 36.0 to 41.0% by mass of Ni, 14.0 or more and less than 20.0% by mass of Cr, from 0.01 to 3.0% by mass of Mo, from 0.1 to 1.0% by mass of Al, from 1.0 to 2.5% by mass of Ti, and from 2.0 to 3.5% by mass of Nb, with the balance being Fe and unavoidable impurities; (2) the precipitation hardened Fe—Ni alloy satisfying the following formulae: Ni≧6×Nb+17 and Nb/(Ti+Al)≧0.8. |
