Inconel 625 (L-PBF, Renishaw In625-0402, as-built)

Renishaw In625-0402 printed by laser powder bed fusion is the maker's grade of the nickel-based alloy Inconel 625 in the as-built state, without heat treatment. Rapid solidification gives a fine cellular-dendritic microstructure with niobium and molybdenum segregated at cell boundaries and columnar grains along the build direction, so properties are anisotropic. Parts carry high residual stress, need supports and have a rough surface. Stress relief, often hot isostatic pressing or solution annealing, and machining usually follow. It is used for corrosion- and heat-resistant parts such as aerospace exhaust and combustion hardware, heat exchangers and chemical-processing components. 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.
