800HT (UNS N08811) yog dual-certifiable Nickel-Iron-Chromium cov ntaub ntawv uas tiv taus oxidation, carburization thiab lwm yam kub corrosion. Cov tshuaj muaj pes tsawg leeg ntawm cov alloys zoo ib yam rau Alloy 800 (UNS N08800), tshwj tsis yog cov qib siab dua ntawm cov pa roj carbon tam sim no hauv ob qib (0.05 - 0.10%) hauv alloy 800H, thiab (0.06 - 0.10%) nyob rau hauv alloy 800HT. Alloy 800HT kuj muaj qhov sib ntxiv ntawm 1.0% txhuas thiab titanium. Daim ntawv thov: Tshuaj thiab Petrochemical Processing - txheej txheem khoom siv rau zus tau tej cov ethylene, ethylene dichloride, acetic anhydride, ketene, nitric acid thiab oxy-cawv, lub zog tsim, thermal ua fixtures.

UNS N08811 alloy muaj cov yam ntxwv hauv qab no:
1. Zoo heev corrosion kuj nyob rau hauv aqueous media ntawm qhov kub siab heev mus txog 500 degree
2. Zoo heev tiv thaiv kev ntxhov siab corrosion
3. Zoo heev machinability
Metallographic qauv:
Lub ntsej muag-centered cubic lattice qauv. Cov ntsiab lus tsis tshua muaj carbon tsawg thiab qhov nce Ti: C piv ua rau muaj kev ruaj ntseg ntawm cov qauv thiab qhov siab tshaj plaws tsis kam mus rau rhiab heev thiab intergranular corrosion. Tsawg-kub annealing nyob ib ncig ntawm 950 degree kom muaj cov qauv zoo.
Corrosion kuj:
Nws tuaj yeem tiv thaiv corrosion los ntawm ntau cov xov xwm corrosive. Nws cov ntsiab lus siab nickel muab nws ua haujlwm zoo rau kev ntxhov siab corrosion tawg nyob rau hauv aqueous corrosion tej yam kev mob. Cov ntsiab lus siab chromium muab nws zoo dua rau pitting thiab crevice corrosion cracking. Cov hlau muaj qhov ua tau zoo rau nitric acid thiab organic acid corrosion, tab sis txwv corrosion kuj nyob rau hauv sulfuric acid thiab hydrochloric acid. Ntxiv nrog rau qhov ua tau ntawm pitting corrosion hauv halides, nws muaj qhov zoo corrosion kuj hauv oxidizing thiab non-oxidizing ntsev. Nws kuj muaj qhov zoo corrosion kuj nyob rau hauv dej, chav, thiab sib tov ntawm chav, cua, thiab carbon dioxide.
