摘要（英）：

The invention provides a nickel material which has excellent corrosion resistance and high strength and a method for producing the nickel material. A nickel material according to one embodiment of thepresent invention has a chemical composition which contains, in mass%, 0.001-0.20% of C, 0.15% or less of Si, 0.50% or less of Mn, 0.030% or less of P, 0.010% or less of S, 0.10% or less of Cu, 0.15%or less of Mg, 0.005-1.0% of Ti, 0.040-1.0% of Nb, 0.40% or less of Fe, 0.01-0.10% of sol. Al and 0.0010-0.080% of N, with the balance being made up of Ni and impurities, and which satisfies formula(1) and formula (2). 0.030 <= (45/48)Ti + (5/93)Nb - (1/14)N < 0.25 (1) 0.030 < (3/48)Ti + (88/93)Nb - (1/12)C (2) (In formula (1) and formula (2), element symbols represent respective contents (mass%) of corresponding elements.)
