UNS Incoloy 800

Profile

This page is mainly introduced the Incoloy 800 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of Incoloy 800,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
Cr content is usually 15-25% of the 800 alloy, nickel content is 30-45%, and contains a small amount of aluminum and titanium.800 alloy from high temperature fast cooling after all in a single austenite zone, therefore, using a state as a single austenitic organization.Alloy has the high chromium content and plenty of nickel content, so a higher resistance to high temperature corrosion performance, more in industrial application.In the chloride, low concentration of NaOH aqueous solution and high temperature and high pressure water, has good resistance to stress corrosion cracking performance, so the equipment used in the manufacture of resistance to stress corrosion cracking Incoloy800 similar brands China: 0 cr20ni32alti America: No8800 Japan: NCF800 west: X2NiCrAlTi3220 Incoloy800 nuclear generator application fields of chemical industry Nitric acid cooler, acetic anhydride, cracking tube heat exchange equipment heat exchange
