Abstract:
1. A nickel-based alloy improved in oxidation-resistance, high temperature strength and hot workability consisting essentially of, in mass percentage, C: 0.003 to 0.1%, Si: 1.0% or less, Mn: 2.0% or less, Cr: 12 to 32%, Fe: 20% or less, Al: less than 2.0%, Mg: 0.001 to 0.04%, at least one element, of not more than 2.5% in total, selected from the group consisting of Nb, Ta and V, impurity elements of S: 0.01% or less, but the ratio of the Mg-content to the S-content being 1 or more, and Ti: 0 inclusive to 0.02%, and the rest being Ni and incidental impurities, wherein an average diameter of a circle equivalent to a compound particle of Nb, Ta and V is not more than 2.0 μm.
