An object of the present invention is to provide a Ni-based alloy which is excellent in mechanical properties and grindability at high temperatures and is relatively inexpensive. SOLUTION: By weight, C: 0.01 to 0.15%, Si: 1% or less, Mn: 1% or less, P: 0.02% or less, S: 0.01% or less, Co: 0 Less than 10%, Cr: 16-22%, Mo: 4-10%, W: 5% or less, Al: 1.2-2.5%, Ti: 2.4-4%, B: 0.001 -0.05%, Zr: 0.01-0.5%, Fe: 1% or less, with the balance being a Ni-base alloy substantially consisting of Ni and inevitable impurities. Mo + 1 / 2W is preferably in the range of 4 to 10%. [Selection figure] None |
