EOS NickelAlloy IN939 opens is well suited for additive manufacturing of industrial gas turbines and other energy industry applications.
EOS has added a new nickel alloy material to its portfolio of metal powders available for use in powder bed additive manufacturing (AM). EOS NickelAlloy IN939 is a nickel-chromium alloy which provides a good balance of strength in high-temperature settings, resistance to corrosion and oxidation, fatigue performance and creep strength at temperatures up to 850°C (1,560°F).
The material offers greater tensile properties, validation, reliability and crack-resistance than similar materials currently on the market, the company says. Parts produced using EOS NickelAlloy IN939 can also be hardened after being manufactured by applying precipitation-hardening heat treatments.
For processing on the EOS M 290 metal AM platform, these qualities make EOS NickelAlloy IN939 well suited for use in creating industrial gas turbines (vanes, blades, heatshields), as well as microturbines, turbochargers, power industry parts and other energy industry applications exposed to high temperatures and extreme elements.

GE Additive’s Ehteshami says, “To make these parts the ordinary way, you typically need 10 to 15 suppliers, you have tolerances, you have nuts, bolts, welds and braces.” With additive, “all of that went away.” The helicopter project is a detail in a story worth knowing.
