AMS 5667 compliant Inconel 939 powder

Inconel 939 powder is a high-temperature, nickel-based superalloy 939 powder with excellent oxidation resistance, creep strength, and phase stability up to 980°C. Alloy 939 powder is produced via Gas Atomization (GA), Plasma Atomization (PA), or PREP, yielding highly spherical, flowable powder for additive manufacturing (AM), thermal spray, and powder metallurgy. Typical compositions include 22–23% Cr, 18–20% Co, 3.6–4.2% Ti, and 1.4–1.8% Al, ensuring superior mechanical properties. Gas-atomized Inconel 939 spherical powder (15-53μm, Hall flow ≤25s/50g) is fully compatible with additive manufacturing (SLM/LPBF, EBM), thermal spray (HVOF, plasma spray), and powder metallurgy (MIM, HIP) processes.

Princeton Powder is a leading supplier of  Inconel 939 powder. Inconel powders including Inconel 625 Nickel Alloy 625 Spherical Powder, Inconel 718 Spherical Powder, and Spherical Inconel 738 Powder are for sale in bulk.

Laser powder bed fusion of the Ni superalloy Inconel 939 using pulsed wave emission

Abstract: The aim of this work is to determine the laser powder bed fusion (LPBF) processability window for the fairly weldable Inconel 939 (IN939) alloy using pulsed wave (PW) laser emission. With that goal, a design of experiments strategy was put in place with the aim of finding out the laser power, scan speed and hatch distance parameters that would render the lowest defect density. Also, a combination of characterization techniques, including optical microscopy, electron backscattered diffraction, and transmission electron microscopy was utilized to examine the microstructure of as-built and heat treated samples at different length scales.

FAQ Hot Isostatic Pressing HIP Inconel 939 IN939 Powder

How does Inconel 939 compare to 718?

    • 939: Higher temp capability (1100°C vs 700°C), better oxidation resistance

    • 718: Age-hardenable, better weldability, lower cost
