About this file

This file is an Inquiry of Availability line item specification for a federal procurement by the Naval Research Laboratory (NRL). The document specifies the requirement for 20 Rotating Bending Fatigue (RBF) specimens to be manufactured per drawing RBF-V2P0-20240514 (Version 24). The specimens must be machined from Nitronic 50 stainless steel (UNS S20910) blanks supplied by NRL, measuring 9 inches long by 0.85 inches in diameter. The parts are identified by sample numbers across two billets: RBF1 through RBF14 from Billet 2 and RBF15 through RBF20 from Billet 3, with identification numbers to be maintained on the ends of finished parts.

The specification requires vendors to comply with all blueprint notes, with particular emphasis on polishing instructions, inspection requirements, and packaging protocols to ensure conforming parts. This procurement is issued as a Request for Quotations (RFQ) under solicitation number N00173-26-Q-1301323349 on a firm-fixed-price basis, classified as commercial items under NAICS code 334516 and PSC 6640. The Department of the Navy Secretary of the Navy Office of Naval Research is the procuring agency, and the machining services support SSNX shafting materials development.
