Equivalent materials: Ni-SA 939LC GD 939 is a vacuum induction melted, argon gas atomized, and spherical powder for additive manufacturing. The strengthening mechanism is a combination of precipitation hardening of gamma prime phases (Ni 3 (Al, Ti) ) phases and the carbides, also solid solution strengthening. With a service temperature of up to 700 °C and a good balance of mechanical properties, like fatigue and creep is the GD 939 a good candidate for high temperature applications like aerospace and land-based gas turbine components with high service temperatures.
