Incoloy 800 / 800H / 800HT (UNS N08800 / N08810 / N08811) super alloy good resistance to stress corrosion
General Overview:
Incoloy 800 is a non-magnetic alloy that offers good overall corrosion resistance, especially in acidic and caustic environments.
Incoloy 800H is a modification of Incoloy 800 with added aluminum and titanium, which allows for precipitation hardening.
Incoloy 800HT is designed for high-temperature applications and offers improved mechanical properties over Incoloy 800 and 800H.
Applications:
Suitable for applications in the aerospace industry, industrial furnaces, and power generation equipment where high-temperature strength and corrosion resistance are critical.
In summary, Incoloy 800, 800H, and 800HT are versatile alloys with a range of properties that make them suitable for a variety of high-temperature and corrosive applications. Their high performance and reliability have led to their widespread use in industries such as chemical processing, power generation, and aerospace.
