Hastelloy C276 (UNS N10276) Precision Tubing
Seamless nickel-moly-chromium tubing engineered for severe chemical heat exchangers, condensers, and hydraulic instrumentation.
ASTM B622 UNS N10276 Heat Exchanger & Instrumentation Tube
Starlight Tubes manufactures high-precision Hastelloy C276 (UNS N10276 / DIN 2.4819) seamless tubing. Designed for maximum thermal efficiency and resistance to localized corrosion, our C276 tubes are manufactured with tight dimensional tolerances, bright annealed surface finishes, and full eddy current inspection.
We supply C276 tubes in straight lengths up to 18 meters and precision U-bent configurations for shell and tube exchangers. Every lot undergoes hydro testing up to 600 bar, flaring, flattening, and full chemical PMI verification.
