About this file
This Statement of Work details NASA's requirements for GRX-810 alloy powder for L-PBF and DED additive manufacturing processes. NASA seeks approximately 750 pounds total, comprising 500 pounds of L-PBF (15-45um diameter) and 250 pounds of DED (45-105um diameter) powder.
The powder must meet specific chemical composition requirements, with precise percentages for elements including Al (0.15-0.45%), Cr (28.75-31.25%), Co (30.75-33.25%), Nb (0.7-1.0%), Re (1.4-1.6%), Ti (0.15-0.35%), and W (2.5-3.5%), with Nickel as the balance. Vendors must be pre-approved on NASA's IP list for GRX-810 Powder and qualified through rapid rupture testing. The powder must pass Hall Flow Funnel testing with a 2.5mm orifice. Lead time is 6-12 weeks, with delivery required to NASA Glenn Research Center in Cleveland, OH. Material certifications including chemistry, particle size distribution, and flow test results must be provided upon completion.

STATEMENT OF WORK / Specifications for NASA Alloy GRX-810 Powder 1/10/2024
The supplier shall provide all labor and equipment necessary to supply coated alloy powder of the composition given below for L-PBF and DED AM.
Powder quantity purchased will depend on price/lbs., but approximately 750 lbs. total is planned for the specified powder size cuts. 500 lbs. of L-PBF (15-45um dia.) and 250 lbs. of DED (45-105um dia.)
The actual chemistry of the screened powder shall be analyzed using LECO, ICP, and reported in the certifications.
The powder shall flow through a Hall Flow Funnel with a 2.5 mm (0.1”) orifice following ASTM standards.
Powder chemistry is below (weight percent).
This action is limited to vendors who have been approved on the NASA IP list for GRX-810 Powder only.
Vendor needs to have been qualified by NASA prior to purchase (Rapid rupture test at elevated temperature).
Lead time 6-12 weeks
