EOS NickelAlloy IN718 Powder Processed by DMSL
Categories:	Metal; 3D Printing/Additive Manufacturing Metal; Nonferrous Metal; Nickel Alloy
Material Notes:	Description: Parts built from EOS NickelAlloy IN718 have chemical composition corresponding to UNS N07718, AMS 5662, AMS 5664, W.Nr 2.4668, DIN NiCr19Fe19NbMo3. 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). 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. Parts built from EOS NickelAlloy IN718 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 - see Technical Data for examples. Heat treatment procedure per AMS 5662: 1. Solution Anneal at 980 °C (1800 °F ) for 1 hour, air (/argon) cool. 2. Ageing treatment; hold at 720 °C (1330 °F ) 8 hours, furnace cool to 620 °C (1150 °F ) in 2 hours, hold at 620 °C (1150 °F ) 8 hours, air (/argon) cool. Heat treatment procedure per AMS 5664: 1. Solution Anneal at 1065 °C (1950 °F ) for 1 hour, air (/argon) cool. 2. Ageing treatment; hold at 760 °C (1400 °F ) 10 hours, furnace cool to 650 °C (1200 °F ) in 2 hours, hold at 650 °C (1200 °F ) 8 hours, air (/argon) cool Information provided by Proto3000
