Hastelloy C276 tube is a high-performance nickel-molybdenum-chromium alloy widely used in chemical processing, offshore engineering, power generation, pollution control, and other severe corrosion environments. Many buyers search for stable and professional C276 tube suppliers that can provide seamless, welded, bright-annealed, and customized tubing with consistent quality and fast delivery. Below is a detailed, well-structured supplier-style article written fully in English.

What Is Hastelloy C276 Tube
Hastelloy C276 (UNS N10276) tube is known for excellent resistance to strong acids, chloride-rich fluids, seawater, and high-temperature oxidizing media. Manufacturers usually supply it according to ASTM B622 (seamless) and ASTM B626 (welded). Typical forms include seamless tube, welded tube, capillary tube, heat-exchanger tube, and precision instrument tube.
Main Types of C276 Tubes
| Tube Type | Features | Applications |
|---|---|---|
| Seamless Tube | High strength, uniform structure | Heat exchangers, high-pressure systems |
| Welded Tube | Cost-effective, large sizes available | General piping, industrial exhaust |
| Bright Annealed Tube | Smooth inner surface | Instrumentation, precision flow systems |
| Thick-Wall Tube | Excellent pressure resistance | Chemical reactors, steam systems |
| Capillary Tube | Small OD, tight tolerance | Measurement, laboratory equipment |
