Abstract

The present invention relates to an additive manufacturing wire, containing, in terms of % by mass, 0%<Si≤2.0%, 0%<Mn≤6.0%, 3.0%≤Ni≤15.0%, 20.0%≤Cr≤30.0%, 1.0%≤Mo≤5.0%, 0%<N≤0.50%, with a balance being Fe and unavoidable impurities, in which C≤0.10% is satisfied, and 27<A<67 is satisfied, when Cris defined as Cr+Mo+1.5Si+0.5(Nb+W)+2(Ti+Al), Niis defined as Ni+30C+20N+0.5(Mn+Cu+Co), and A is defined as −16.2+6.3Cr−9.3Ni, here, in the definition of Crand Ni, each element symbol indicates a content of the each element in units of % by mass.
