BAR,METAL

The Department of the Navy, NAVSUP Weapon Systems Support, is soliciting proposals for cold-drawn, stress-relieved nickel-copper alloy hexagon metal bars. The contractor must manufacture and deliver these specialty metal bars in accordance with QQ-N-281 specifications, with some sizes requiring ultrasonic testing and rigorous objective quality evidence. Because the material is designated for crucial shipboard systems with high safety risks, strict Special Emphasis control procedures, material traceability markings, and Portsmouth Naval Shipyard review and acceptance are required before shipping. Interested vendors must submit certification data contract data requirements lists at least 20 days prior to scheduled delivery, with final material delivery expected within 365 days of contract award.
