Abstract: A metal powder for additive manufacturing, comprising, in wt%, Ni 9.0-12.0, Cr 2.0-4.5, Mo 3.5-4.5 and Ti 0.1-1.0; and, if present, Si up to 0.5, Mn up to 0.5, Al up to 0.1, Co up to 0.1, N up to 0.05 and/or C up to 0.07; the balance being Fe and usual impurities. Use of the metal powder for additive manufacturing. A process for producing an object by additive manufacturing, comprising building an object by iteratively melting particles of the metal powder and solidifying the melt, and subsequently aging the built object without any preceding solution annealing thereof.
