What are Incoloy 800H Tubes?
Incoloy 800H Tubes are manufactured from a nickel-iron-chromium alloy with controlled carbon content, providing significantly improved creep rupture strength compared to standard Alloy 800. The alloy maintains excellent mechanical properties even during prolonged exposure to elevated temperatures.
The material is designated as UNS N08810 nickel alloy tube, W.Nr. 1.4958 tube, and DIN 1.4958 nickel tubing across various international specifications.
Because of their excellent metallurgical stability, these tubes are commonly selected for:
- Heat exchangers
- Boilers
- Condensers
- Steam superheaters
- Reformer furnaces
- Petrochemical plants
- Nuclear engineering
- Chemical processing
- Power generation
- Pressure vessels
