摘要
A printed metallic part is provided. The alloy has the composition of Fe at 69.2 wt.% to 89.1 wt.%; Cr at 7.25 wt.% to 16.0 wt.%; Nb at 0.01 wt.% to 10.0 wt.%; Mo at 0.5 wt.% to 4.0 wt.%. C at 0.03 wt. % to 0.4 wt. % and optionally one or more of Ni, Cu, Si, W, Mn, N and B. The printed metallic part has a tensile strength of at least 1300 MPa, a yield strength of at least 700 MPa, an elongation of at least 4.0%, and a hardness of at least 45 HRC.
