EOS NickelAlloy IN939 DMSL on EOS M 290
Categories: Metal; 3D Printing/Additive Manufacturing Metal; Nonferrous Metal; Nickel Alloy
Material Notes: EOS NickelAlloy IN939 is a nickel-chromium alloy which provides an outstanding balance of high temperature strength, corrosion and oxidation resistance, fatigue performance and creep strength at temperatures up to 850 °C (1 560 °F). Parts built from EOS NickelAlloy IN939 can be hardened after manufacture by application of precipitation- hardening heat treatments.

Main Characteristics:

  • Excellent corrosion and oxidation resistance
  • High tensile, fatigue, creep and rupture strength at temperatures up to 850 °C (1 560 °F)
  • Maintains good ductility in age-hardened condition
  • Crack-free in as-built condition and resistant to strain-age cracking
Typical Applications:
  • Industrial gas turbines (vanes, blades, heat-shields)
  • Microturbines
  • Turbochargers
  • Instrumentation parts
  • Power industry parts
  • Process industry parts
