Statement of Work (SOW) for Niobium Raw Material Procurement

This Statement of Work issued by the National Aeronautics and Space Administration (NASA) Marshall Space Flight Center (MSFC) establishes requirements for the procurement of niobium alloy bar stock to support propulsion hardware fabrication. The contract requires delivery of six (6) round bars of Niobium-1% Zirconium (Nb-1Zr) material, measuring 2.75 inches in diameter by 3.50 inches in length, complying with ASTM B392 Type 4 (UNS R04261) in annealed condition. All material must be domestically produced (melted and manufactured in the United States), with cutting and finishing operations also performed within the U.S. The contractor must deliver all material within twelve (12) weeks of contract award. Partial shipments are authorized as material becomes available, provided each shipment includes itemized packing lists, Certified Material Test Reports (CMTR) per EN 10204 3.1, and Certificates of Conformance (CoC) documenting compliance with specifications and domestic production requirements.

The contractor must be either a domestic producing mill or an authorized metals distributor/service center maintaining full heat or lot traceability to the producing mill; brokers and third-party intermediaries without mill traceability are ineligible. All material must be new, unused, and traceable to the original domestic producing mill, and must conform to chemical composition and mechanical properties defined in ASTM B392 Type 4. Within ten (10) business days of contract award, the contractor shall provide a delivery schedule listing estimated ship dates and confirm the ability to deliver within the twelve-week requirement. NASA reserves the right to independently verify chemistry, mechanical properties, dimensions, and country of origin, and material failing verification shall be rejected and replaced at the contractor's expense. The Period of Performance extends from December 1, 2026 through March 31, 2027. Acceptance is conditional upon successful receipt inspection, documentation review, and compliance with all domestic production, dimensional, marking, and certification requirements specified in the SOW.
