Hastelloy X (L-PBF, Velo3D Hastelloy X, as-built)

Velo3D Hastelloy X in the as-built condition is this maker's grade of the nickel-chromium-iron-molybdenum alloy Hastelloy X, made by laser powder bed fusion and not heat treated after printing. Rapid solidification gives a fine cellular substructure within columnar grains elongated along the build direction, so properties vary with build orientation, and strength is higher but ductility lower than in wrought material. Parts carry high residual stress and a rough surface, and are usually stress-relieved, removed from supports, then hot isostatically pressed or solution annealed. Printed parts serve as gas turbine combustor components, fuel nozzles and heat exchangers. 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.
