Hastelloy C-276 Seamless Pipe Tube (UNS N10276 / W.Nr. 2.4819)
High-strength corrosion-resistant alloy Seamless Pipe Tube for Chemical processing and Pollution control
As an industry-leading supplier of nickel-based superalloys, SEATHER TECHNOLOGY manufactures high-quality Hastelloy C-276 (UNS N10276) seamless pipes and tubes engineered for exceptional corrosion resistance and long-term durability.
Hastelloy C-276 is a premium nickel-chromium-molybdenum alloy renowned for its outstanding resistance to a wide range of highly corrosive environments. Its high nickel content ensures superior resistance to stress corrosion cracking, while chromium and molybdenum provide strong resistance to both oxidizing and reducing media. The addition of tungsten and molybdenum enhances the alloy’s mechanical strength, enabling reliable performance in extreme service conditions.
We manufacture Hastelloy C-276 seamless pipes and tubes in strict accordance with ASTM B622, with dimensional tolerances controlled precisely according to ASTM B829. All tubes undergo complete solution heat treatment to ensure a stable microstructure and optimal corrosion resistance. Each pipe is also subjected to hydrostatic testing to guarantee structural integrity and performance under pressure.
Our default surface condition is pickled, ensuring a clean and corrosion-free finish suitable for most industrial applications. For customers requiring enhanced surface quality, we offer customized polishing options to meet specific project or equipment requirements.
With advanced manufacturing technology, strict quality assurance, and competitive pricing, SEATHER TECHNOLOGY provides reliable Hastelloy C-276 seamless pipe and tube solutions for critical applications in chemical processing, pollution control, marine engineering, and high-temperature environments.

More Information About Hastelloy C-276 Seamless Pipe Tube (UNS N10276)
When you choose to buy Hastelloy C-276 Seamless Pipe Tube (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)
