TRUER SPHERE - N0939
Nickel Alloy N0939 powder, known as Inconel 939 or IN 939, is a precipitation hardening superalloy which high tensile strength, high hot fatigue resistance and oxidation resistance at temperature to 850 °C.
For additive manufacturing application, our common production process includes Gas (argon or nitrogen) Atomizing process (GA) & Plasma Rotating Electrode Process (PREP) with high spherical, high purity, high packing density, low porosity and excellent flowing properties.
