Double Eagle Alloys supplies long bar in a wide range of corrosion-resistant and high-performance alloys for machining, fabrication, and structural applications. Our inventory spans nickel alloys, stainless steels, duplex and super duplex grades, carbon and alloy steels, and bronze, supporting consistent chemistry, tight tolerances, and reliable performance across a variety of end uses.
Available in a range of diameters and lengths, our long bar can be supplied to meet ASTM, AMS, ASME, NACE, and customer-specific requirements, with additional processing available to deliver material ready for production.
Pump Shaft Quality (PSQ) Long Bar
While we offer long bar for a broad range of applications, Double Eagle Alloys is best known for our expertise in Pump Shaft Quality (PSQ) bar. PSQ long bar is specifically produced for rotating equipment and shafting applications, where straightness, surface finish, and material integrity are critical to performance. These are not standard requirements as PSQ bar is held to tighter controls to ensure reliability in demanding environments.
Key characteristics of PSQ long bar include:
- Tight straightness tolerances for smooth rotation and reduced vibration
- Enhanced surface finish to support seals, bearings, and critical interfaces
- Consistent chemistry and mechanical properties across the full length
- Suitability for precision machining and finishing operations
PSQ bar is commonly used in:
- Pump shafts
- Mixer shafts and agitators
- Rotating equipment in oil & gas, chemical processing, and power generation
- Applications where alignment, balance, and wear resistance are critical
Available Alloys
We supply long bar across a broad range of material families:
Corrosion Resistant Alloys
Duplex & Super Duplex
Nitronic
