Cov ntsiab lus dav dav ntawm Incoloy 800 alloy:

Cov ntsiab lus dav dav ntawm Incoloy 800 alloy:

Incoloy 800 (0Cr20Ni32AlTi) muaj kev tiv thaiv zoo rau kev txo qis, oxidation, thiab nitriding media corrosion thiab tsis kam rau alternating redox media corrosion kev ua tau zoo, thiab muaj kev ruaj ntseg metallurgical nyob rau hauv qhov kub thiab txias kev siv mus sij hawm ntev. Ntau yam kev ua yeeb yam tuaj yeem raug coj mus ua si ntawm sub-zero, chav tsev kub thiab 600 degree kub. Feem ntau siv rau hauv cov khoom siv hluav taws xob sib txuas, lub tshuab nqus dej nthuav dav sib koom ua ke, hluav taws xob cua sov raj, steel mills, cov khoom siv kho cua sov, acetic acid gypsum ntau lawm thiab kev lag luam nuclear, thiab lwm yam. Nws yog qhov zoo dua li Incolo 600 thiab Monel 400 alloy hauv kev tsim cov khoom siv corrosion-resistant kev nyuaj siab tawg.

Daim ntawv thov ntawm Incoloy 800 alloy hluav taws xob cua sov raj ntawm qhov kub thiab txias

Daim ntawv thov feem ntau ntawm 800 alloy yog cov ntawv thov kub, xws li cov khoom siv hluav taws xob, petrochemical hloov kho, hydrocracking yeeb nkab fittings, superheated chav kho cov cuab yeej hauv cov pa fais fab nroj tsuag thiab nuclear fais fab nroj tsuag. Cov ntsiab lus siab ntawm chromium thiab npib tsib xee ua rau 800 series alloys muaj kev tiv thaiv zoo rau oxidation thiab carbonization.

Hluav taws xob cua sov raj Incoloy 800 alloy tsis tiv thaiv corrosion

Txawm hais tias 800 series alloy tsis muaj kev tiv thaiv rau chloride ion kev nyuaj siab corrosion cracking, nws cov corrosion kuj tseem zoo heev. Nws muaj corrosion kuj zoo nyob rau hauv roj av, tshuaj, zaub mov, pulp thiab ntawv industries. Pom tseeb, 800 series alloy tuaj yeem siv rau hauv ib puag ncig corrosive uas ua rau muaj kev ntxhov siab corrosion ntawm cov hlau tsis zoo austenitic. Txawm li cas los xij, 800 series alloy tsis muaj kev tiv thaiv rau kev ntxhov siab corrosion cracking ntawm MgCl2 tov.

Corrosion kev ua tau zoo thiab daim ntawv thov ntawm Incoloy 800 alloy cua sov raj:

Cov ntsiab lus nickel ntawm 800 series alloy yog ntau dua li ntawm 304 stainless hlau tsev neeg. Hauv ntau qhov xwm txheej, 800 series alloy thiab 304 stainless hlau zoo sib xws. Piv txwv li, nyob rau hauv ntau cov khoom siv roj thiab tshuaj lom neeg xws li nitric acid thiab organic acids, lawv zoo sib xws. kev ua tau zoo. Tsis yog 800 series alloy lossis 304 stainless hlau tuaj yeem siv nyob rau hauv ib puag ncig sulfuric acid, tshwj tsis yog tias nws tsis kub thiab tsis tshua muaj siab. Zoo li austenitic stainless hlau, yog hais tias 800 series alloy yog rhuab ntev heev nyob rau hauv qhov ntau ntawm 538 degree -760 degree, chromium carbides yuav precipitate ntawm grain ciam teb ntawm cov alloy, uas yuav sensitize lub alloy thiab ua rau cov alloy coj. zoo li pickling. Intergranular corrosion tshwm sim nyob rau hauv ib puag ncig ntawm qhov kub thiab txias thiab 65 feem pua ​​nitric acid.
