Hastelloy C-276 Coiled Tubing (UNS N10276 / W.Nr. 2.4819)
High-strength corrosion-resistant alloy Coiled Tubing for Chemical processing and Pollution control
As a leading supplier of Hastelloy tubing solutions, SEATHER TECHNOLOGY specializes in manufacturing high-quality, fully customized Hastelloy C-276 coiled tubing for critical and corrosive applications.
Hastelloy C-276 (UNS N10276) is a nickel-chromium-molybdenum alloy developed with extremely low carbon and silicon content, effectively reducing welding concerns and improving fabrication reliability. With more than 50 years of proven performance in the chemical processing industry, C-276 remains one of the most versatile and corrosion-resistant superalloys available today.
Hastelloy C-276 coiled tubing is produced as a continuous, small-diameter tube by welding, precision cold drawing, and coiling high-grade C-276 strip. To maintain a clean inner surface and avoid oxide formation, all coiled tubes are processed using bright annealing. The resulting tubing offers excellent corrosion resistance, high-temperature stability, and mechanical integrity, making it suitable for harsh and demanding environments.
We offer both seamless and welded Hastelloy C-276 coiled tubing options. Due to process differences, seamless coils typically come in shorter continuous lengths than welded coils of the same size—please confirm your specific requirements with us so we can recommend the most suitable option.
With advanced production technology, strict dimensional control, and customizable specifications, SEATHER TECHNOLOGY delivers Hastelloy C-276 coiled tubing that meets the highest standards of quality, reliability, and performance.

More Information About Hastelloy C-276 Coiled Tubing (UNS N10276)
When you choose to buy Hastelloy C-276 Coiled Tubing (UNS N10276), there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Hastelloy C-276
Hastelloy C-276 PREN: 68.3
The pitting resistance equivalency number uses the alloy’s chemical makeup to guess its power against pitting corrosion. You check how much chromium, molybdenum, tungsten, and nitrogen are in the alloy. These elements help keep the steel safe. The most used formula is:
PREN = CR% + 3.3 x (MO% + 0.5 x W%) + 16 x N%How to Purchase Hastelloy C-276 Seamless Pipe Tube (UNS N10276)
