A Ni-Cr alloy with very good high temperature stability
Good high temperature strength- Oxidization and carburization resistant at high temperatures
- Good corrosion resistance, which increases with the various grades
- Download the Incoloy 800 datasheet and 825 datasheet
Not to be confused with Inconel, Incoloy threaded rods are made of a nickel alloy which contains iron and a lower content of nickel. Incoloy is essentially a more economical option to Inconel, yet with more restricted corrosion resistance and temperature limits. Typically, Incoloy is an ideal material for long-term exposure in high temperature environments due to its oxidation, carburization and creep resistance. Incoloy is widely used for its resistance to seawater, brine, sour gas and high chloride environments at elevated temperatures, which make it a popular choice in the oil and gas and power industries.
The most commonly used grades of Incoloy threaded rods are Incoloy 800, 800H, 800HT; Incoloy 825; and Incoloy 925. For more indepth information on these specific grades, visit our specific web pages or contact one of our engineering experts:
