Inconel 718 (L-PBF, Renishaw In718-0405)

Renishaw In718-0405 is that maker's Inconel 718 powder grade for laser powder bed fusion, used to print the precipitation-hardening nickel superalloy layer by layer. As printed, it has a fine cellular-dendritic structure with niobium segregation, columnar grains along the build direction that make properties anisotropic, and high residual stress. Parts are usually stress relieved before removal from the plate and supports, then often hot isostatically pressed and solution treated and aged to precipitate the strengthening phases. Typical uses are gas turbine and rocket engine parts such as combustor components, brackets and manifolds with complex internal passages. Every value on this page is read from Renishaw'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.
