Nickel Alloy, Corrosion and Heat-Resistant, Powder for Additive Manufacturing, 60Ni - 22Cr - 2.0Mo - 14W - 0.35Al - 0.03La (Compositions similar to UNS N06230)
This specification covers a corrosion and heat-resistant nickel alloy in the form of pre-alloyed powder.
This powder is intended to be used for the additive manufacturing of aerospace parts via a powder bed process, but usage is not limited to such applications.
Maximum oxygen concentration is specified as follows:
Class A: Maximum oxygen concentration of 150 ppm.
Class B: Maximum oxygen concentration of 300 ppm.
Class C: Maximum oxygen concentration of 400 ppm.
Rationale: A desired outcome of the Air Force Research Laboratory (AFRL) Materials Affordability Initiative (MAI) HON-9 program is to provide a specification that will allow Alloy 230 to be procured in the aerospace supply chain for use in additive manufacturing.
