Comparison of Incoloy 800 alloy tube with other high temperature alloys
Incoloy 800 alloy tubes have excellent high temperature strength, oxidation resistance, and carburization resistance, making them suitable for a variety of demanding applications. Compared to other high temperature alloys, such as Inconel 600, Incoloy 800 excels in applications requiring strength up to 1500°F (816°C). However, Inconel 600 may be more suitable for applications up to 2000°F (1095°C). Incoloy 800H and 800HT are modified versions of Incoloy 800 that have higher creep and rupture strengths, making them suitable for higher temperature ranges.
What is the maximum service temperature of Incoloy 800 alloy?
Incoloy 800 alloy (UNS N08800/W. Nr. 1.4876) is a material widely used in the manufacture of equipment requiring corrosion resistance, heat resistance, high strength and high stability, with a maximum service temperature of up to 1500°F (816°C).
What are the temperature limits of Incoloy 800?
If deformation is 5% or more, the hot working temperature range for Incoloy 800H and 800HT alloys is 950-1200°C (1740-2190°F). If hot deformation is less than 5%, the recommended hot working temperature range is 850-1050°C (1560-1920°F).
Benefits of Using Incoloy 800 Tubing
Incoloy 800 Tubing Resists a Variety of Corrosive Environments
Incoloy 800 Tubing is ideal for corrosive environments due to its high chromium and nickel content. The addition of these elements gives the alloy excellent resistance to a wide range of acids, bases, and salts.
Incoloy 800 Tubing Resists High Temperatures
Another benefit of using Incoloy 800 Tubing is its high temperature resistance. The alloy can withstand temperatures up to 750 degrees Celsius (1500 degrees Fahrenheit) without sacrificing strength or corrosion resistance.
Incoloy 800 Tubing Has Excellent Weldability.
Incoloy 800 Tubing also has excellent weldability, making it easy to join sections of the tube using welding methods such as TIG or MIG.
Incoloy 800 Tubing Is Non-Magnetic
Incoloy 800 Tubing is also non-magnetic, which is important in certain applications where magnetic materials are not required.
Comparison of Incoloy 800 Tube to Other High-Temperature Alloys
Incoloy 800 Tube is made of nickel, chromium, and iron, which provides excellent resistance to oxidation, carburization, and other forms of high-temperature corrosion. In contrast, 625 alloy is made of nickel, chromium, and molybdenum, making it more resistant to pitting and crevice corrosion in harsh environments. Although 625 alloy is commonly used in high-temperature applications, it may not be as effective as Incoloy 800 alloy in resisting high-temperature corrosion. The higher nickel content of Incoloy 800 alloy forms a tightly bound oxide layer, which provides excellent resistance to thermal cycling.
Another high-temperature alloy used in harsh environments is 800H alloy, which is an upgrade of Incoloy 800. Incoloy 800 Tube has a maximum carbon content of 0.10%, while 800H alloy has a higher carbon content of up to 0.15%. This makes 800H alloy more resistant to high-temperature creep and rupture. However, the disadvantage of 800H alloy is that it has poorer corrosion resistance due to the higher carbon content. When choosing between Incoloy 800 Tubing and 800H Alloy, the specific application and environmental conditions should be considered to ensure the correct selection is made.
