What is Incoloy 800?
Incoloy 800 is a nickel-iron-chromium austenitic alloy known for its exceptional performance in high-temperature and corrosive environments. The alloy features a stable austenitic structure that remains stable even after rapid cooling from elevated temperatures, a characteristic that enables it to perform excellently under severe service conditions, thus making it an ideal material for manufacturing the Incoloy 800 Double End Stud.

Chemical Composition
The typical chemical composition of Incoloy 800 consists of nickel content between 30–35%, chromium content between 19–23%, with iron as the balance, along with additions of 0.15–0.60% aluminum and 0.15–0.60% titanium. This unique combination of elements gives the alloy its excellent comprehensive properties—the high nickel content provides outstanding resistance to stress corrosion cracking, while the chromium content ensures superior oxidation resistance at elevated temperatures. These properties enable the Incoloy 800 Double End Stud made from Incoloy 800 to perform stably under severe operating conditions.
