A Ni-base alloy having high-Cr and corrosion resistance at high temperature, and a member having corrosion resistance at high temperature are provided to prevent the toughness drop of the alloy by reducing the content of Mo and restricting aging precipitation of a sigma phase resulting from the Mo. A Ni-base alloy having high-Cr and corrosion resistance at high temperature comprises Ni: 45 to 50wt%, Cr: 30 to 35wt%, Mo: greater than 0.5wt% to less than 4.5wt%, Si: greater than 3.0wt% to less than 6.0wt%, C: 0.18 to 0.28wt%, and the remainder Fe and unavoidable impurities. |
