Provided is an Fe—Ni—Cr alloy that has excellent surface characteristics and enables formation of a blackened coating having excellent blackening characteristics and peeling resistance. The Fe—Ni—Cr alloy has a chemical composition containing, by mass %, C, Si, Mn, P, S, Cr, Ni, Mo, Co, Cu, N, Ti, Al, O, and H, the balance being Fe and inevitable impurities, and satisfying formulae (1) to (4): (1) T1=11×[% N]+0.1; (2) T2=−39×[% N]−1.0; (3) A1=7.5×[% N]+0.1; (4) A2=−42.5×[% N]+1.0, where [% M] represents content (mass %) of element M in the alloy, and T1, T2, A1, and A2 satisfy relationships T1[% Ti]T2 and A1[% A1]A2.
