Inconel 600 Capillary Tube (UNS N06600 / W.Nr. 2.4816)
High-strength corrosion-resistant Capillary Tube for chemical processing
As a leading Inconel supplier in China, SEATHER manufactures and supplies high-precision Inconel 600 capillary tubes for demanding applications.
INCONEL® alloy 600 (UNS N06600 / W.Nr. 2.4816) is a nickel-chromium-iron alloy widely used in environments requiring excellent corrosion resistance, high-temperature stability, and reliable mechanical properties. The alloy offers an ideal combination of high strength and good workability, making it suitable for precision tubing applications.
Inconel 600 capillary tube is a small-diameter, thin-wall alloy tube that requires advanced processing technology. It is typically produced from straightened and polished Inconel 600 coil tubing. These capillary tubes are especially suitable for applications requiring superior corrosion resistance, stable performance, and highly accurate internal flow control.
We offer both seamless and welded Inconel 600 capillary tubes to meet different engineering and cost requirements. During surface finishing, we provide multiple polishing options—including MP, EP, BA, and AP—to ensure the internal and external surfaces meet your exact specifications.
The Inconel 600 capillary tubes produced by SEATHER feature excellent surface quality, tight dimensional tolerances, and consistent performance, making them a reliable choice for precision instruments, control systems, chemical analysis equipment, and other high-end applications.

What is Inconel 600 (UNS N06600)
Alloy 600 also referred to as the UNS N06600, W.Nr. 2.4816 alloy.
The alloy also has excellent mechanical properties and presents the desirable combination of high strength and good workability.
The alloy is not precipitation hardenable; it is hardened and strengthened only by cold work.
The versatility of alloy 600 has led to its use in a variety of applications involving temperatures from cryogenic to above 2000°F (1095°C).
In the aeronautical field, alloy 600 is used for a variety of engine and airframe components which must withstand high temperatures. Examples are lockwire, exhaust liners and turbine seals.
The alloy 600 is used in the electronic field for such parts as cathode-ray tube spiders, thyratron grids, tube support members and springs.

More Information About Inconel 600 Capillary Tube
When you choose to buy Inconel 600 Capillary Tube (UNS N06600), there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Inconel 600 Capillary Tube
Inconel 600 PREN: 16
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 Inconel 600 Capillary Tube (UNS N06600)
