Abstract
An Fe-based alloy for melting-solidification shaping including, in mass %: 18.0≤Co<25.0; 12.0≤Mo+W/2≤20.0; 0.2≤Mn≤5.0; 0.5≤Ni≤10.0; and 0≤Si≤1.0, with the balance being Fe and unavoidable impurities, and satisfying the following expressions (1) and (2) when [M] represents a content of an element M expressed in mass % basis, 58≤[Co]+3([Mo]+[W]/2)≤95 (1), A/B≥1.6 (2) where A=[Co]+[Ni]+3[Mn], and B=[Mo]+[W]/2+[Si], in which when the Fe-based alloy includes no Mo, the expressions (1) and (2) are calculated using [Mo]=0, when the Fe-based alloy includes no Si, the expression (2) is calculated using [Si]=0, and when the Fe-based alloy includes no W, the expressions (1) and (2) are calculated using [W]=0.
