EOS NickelAlloy IN718 DMSL on EOS M 400-4
Categories:	Metal; 3D Printing/Additive Manufacturing Metal; Nonferrous Metal; Nickel Alloy
Material Notes:	EOS NickelAlloy IN718 chemical composition corresponds to UNS N07718, AMS 5662, AMS 5664, W.Nr 2.4668, DIN NiCr19Fe19NbMo3. This material is ideal for many high temperature applications such as gas turbine parts, instrumentation parts, power and process industry parts etc. It also has excellent potential for cryogenic applications. This kind of precipitation-hardening nickel-chromium alloy is characterized by having good tensile, fatigue, creep and rupture strength at temperatures up to 700 °C (1290 °F). Parts can be easily post-hardened by precipitation-hardening heat treatments. In both as-built and age-hardened states the parts can be machined, spark eroded, welded, micro shot-peened, polished and coated if required. Due to the layerwise building method, the parts have a certain anisotropy. Heat treatment procedure conform to Aerospace Material Specification AMS 5662: 1. Solution Anneal at 980 °C (1796 °F ) for 1 hour per 25mm (0.98 inch) of thickness, air (/argon) cool. 2. Ageing treatment; hold at 718 °C (1325 °F ) 8 hours, furnace cool to 621 °C (1150 °F ) and hold at 621 °C (1150 °F ) for total precipitation time of 18 hours., air (/argon) cool.
