Incoloy 800 is a high performance super alloy that is known for offering good resistance to corrosion and oxidation.They can retain their mechanical strength at elevated temperature conditions.The incoloy 800 tubes are available in welded, seamless and cold form conditions as per the client's requirements.
They are found in high temperature applications like nuclear engineering pressure vessels, industrial furnaces, heaters in power plants, etc.The incoloy 800 material shows good resistance to corrosion even in acidic environments.
Alloy 800 can be used in very demanding applications, including sanitary & high pressure services.The cold worked DIN 1.4876 heat exchanger tube comes without contamination issues and has a better surface finish.They have superior dimensional accuracy and the low porosity in the EN 1.4876 precision tubes ensures a leakage free sealing.Whereas, hot working the tubes can also improve some of their mechanical and physical properties.
Incoloy 800 tubing has a wide working temperature range of 20-800 °C.This means the tubes can be suitably used in room and elevated temperatures.
They are also highly resistant to oxidizing, carburizing and reducing atmospheres.The microstructure of the incoloy 800 material remains stable at high temperatures and it shows good scaling resistance too.

Incoloy 800 material can become relatively hard in the annealed state.The high hardness can make it difficult to cut nickel alloy 800 welded tubes.Also, it is crucial to use the right cutting tools like the carbide ones which are known for their durability and wear resistance.
Apart from these, selecting the right cutting method and coolant can impact the ease of cutting.Proper selection of cutting speed and feed rate is also very important.
The alloy 800 tube shows ductility under normal operating conditions and temperatures.It can retain its ductile properties in elevated temperature conditions and thus, the tubes can withstand mechanical stress without getting brittle.
However, the inconel 800 tube can become brittle at at extremely low temperatures, below -150 °C.Also in heat treated or annealed conditions, the material is susceptible to hydrogen embrittement.
