Abstract

This Ni-based alloy i s constituted o f chemical components which comprise C , Si, Mn, Cr, Mo, Co, Al, Ti, B , P , S, and, as the remainder, Ni and impurities. If the average crystal grain diameter, in unit of mpi , of the g phase containea m the metallo - graphic structure of this Ni-based alloy is expressed by d , the average crystal grain diameter d, is 10-300 mpi . This metallographic structure has no precipitate grains that have a major-axis length of 100 n m or larger. If the grain boundary coverage index represen - ted by the average crystal grain diameter d and by the contents, in mass%, of some elements among the chemical components is ex pressed by p, this grain boundary coverage index p is equal to or greater than the value of 2 which is represented by the average crystal grain diameter d and by the contents, in mass%, of some elements among the chemical components.
