Fabrication of Inconel 718 Sensing Diaphragms

This subcontract through the NASA Shared Services Center involves the fabrication of precision sensing diaphragms for prime contractors supporting NASA Goddard Space Flight Center projects. The scope of work requires the precision machining and forming of 718 Inconel to ensure high resistance to corrosion when exposed to helium, carbon dioxide, and sulfuric acid environments. To maintain the strict tolerances required for pressure-sensitive membranes, the contractor must utilize chemical etching or high-precision CNC machining. All finished 718 Inconel sensing diaphragms must be delivered accompanied by mill test reports to verify material specifications.
