Inconel 718 (L-PBF, solution treated + double aged)

UNS N07718

Inconel 718 printed by laser powder bed fusion, then solution treated and double aged, is a nickel-chromium-iron superalloy in its precipitation-hardened state. As printed, it has fine columnar grains textured along the build direction, niobium segregation between cells, residual stress and some anisotropy. Solution treatment relieves much of the stress and dissolves segregation, and the double age precipitates the strengthening phases, but porosity and rough surfaces remain, so hot isostatic pressing and machining are often added. Parts are used for turbine and engine hardware, ducting and brackets that must hold strength at elevated temperature.

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
