Velo3D Hastelloy X is the maker's grade of the nickel-chromium-iron-molybdenum alloy Hastelloy X made by laser powder bed fusion, here in the annealed condition. As built, it has a fine cellular structure with columnar grains along the build direction and high residual stress. It is also prone to solidification cracking, which the powder chemistry and process parameters are chosen to limit. Annealing relieves residual stress and partly recrystallizes the as-built structure, trading some strength for ductility and reducing anisotropy between build directions. Parts include gas turbine combustor hardware, fuel nozzles 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.
