UNS N08811 (Incoloy 800HT)
Short Introduction:
-
Incoloy 800HT/Z8NC32.21/W Nr.1.4876/X10NiCrAlTi322/NA15 /UNS NO8811/FeNi32Cr21AlTi is resistant to many corrosive media. Its high nickel content makes it have good resistance to stress corrosion cracking in aqueous corrosion conditions. High chromium content makes it more resistant to pitting and crevice corrosion cracking. The alloy has good resistance to nitric acid, organic acid corrosion, but in sulfuric acid and hydrochloric acid corrosion resistance is limited. Except for the possibility of pitting corrosion in halides, there is good corrosion resistance in oxidizing and non-oxidizing salts. In water, steam and steam, air, carbon dioxide mixture also has good corrosion resistance.
