Zusammenfassung:	A steel powder for use in additive manufacturing processes. The steel powder has a composition comprising (in wt.-%): C 0.25-0.40, Si 0.80-1.35, Mn 0.5 -1.0, Cr 1.1 -1.6, Ni 0.4 -1.3, Mo 0.6 -1.0, V 0.05-0.25, N equal to or less than 0.025, optionally Nb equal to or less than 0.03, optionally Ti equal to or less than 0.02, optionally B equal to or less than 0.005, balance Fe and unavoidable impurities. L'invention concerne une poudre d'acier destinée à être utilisée dans des processus de fabrication additive. La poudre d'acier a une composition comprenant (en % en poids) : C 0,25 à 0,40, Si 0,80 à 1,35, Mn 0,5 à 1,0, Cr 1,1 à 1,6, Ni 0,4 à 1,3, Mo 0,6 à 1,0, V 0,05 à 0,25, N ≤ à 0,025, éventuellement Nb ≤ à 0,03, éventuellement Ti ≤ à 0,02, éventuellement B ≤ à 0,005, le reste étant constitué de Fe et d'impuretés inévitables.
