PROBLEM TO BE SOLVED: To provide a high Nb-containing Ni-based alloy which is excellent in hot workability, crack resistance and corrosion resistance and has a high Nb-containing alloy containing 1.5% by mass or more of Nb. To provide a Ni-based alloy excellent in scale releasability, which can prevent generation of dents and scratches on the alloy surface due to indentation of oxide scale generated in the hot working step, and can obtain excellent yield before and after hot working. To aim. SOLUTION: In mass %, carbon (C): 0.001 to 0.045%, silicon (Si): 0.05 to 1.00%, manganese (Mn): 0.05 to 1.00%, Phosphorus (P): 0.015% or less, sulfur (S): 0.0030% or less, chromium (Cr): 14 to 24%, niobium (Nb): 1.5 to 4.0%, iron (Fe). : 3 to 25%, aluminum (Al): 0.01 to 0.20%, titanium (Ti): 0.001 to 0.20%, nitrogen (N): 0.003 to 0.020%, boron ( B): 0.0010 to 0.0100%, oxygen (O): 0.0002 to 0.0020%, molybdenum (Mo) and/or tungsten (W): 0.005 to 0.25%, balance nickel ( Ni) and unavoidable impurities, and the scale is characterized by satisfying the following formula (wherein the notation of each element means the content (mass %) of the element in the Ni-based alloy)): Ni-based alloy with excellent releasability. 4.2×Mo+3.6×W+355×B≧0.60 [Selection diagram] None
