Inconel 718 (L-PBF, Velo3D Inconel 718)

Velo3D Inconel 718 is the maker's grade of the nickel superalloy Inconel 718 for laser powder bed fusion. As printed, it has a fine cellular-dendritic structure with niobium segregated between cells, columnar grains along the build direction that make properties anisotropic, and high residual stress. Parts are stress relieved before removal from the build plate, then typically hot isostatically pressed and solution treated and aged to precipitate the strengthening phases, with supports removed and rough surfaces machined. Uses include gas turbine and rocket engine parts such as injectors, manifolds and heat exchangers with internal passages. Every value on this page is read from Velo3D's own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
