Kev kho cua sov ntawm Incoloy 800 alloy:

Kev kho cua sov ntawm Incoloy 800 alloy:

Kev kho annealing ntawm 800 alloy feem ntau yog nyob nruab nrab ntawm 982-1038 degree , thiab lub hom phiaj tseem ceeb yog los kho cov nplej. Kev kho cua sov ntawm 800H thiab 800AT feem ntau yog ua los ntawm 1121-1177 degree . Ntxiv nrog rau lub hom phiaj ntawm softening cov khoom, lwm yam yog kom loj hlob grain ntawm cov khoom thiab txhim kho cov creep kuj thiab kev nyuaj siab puas ntsoog kev ua tau zoo. Inconel600 muaj lub zog zoo heev thiab kev ua haujlwm yooj yim. Nws yog tsuas yog siv nyob rau hauv corrosive ib puag ncig. Nws muaj oxidation kuj nyob rau hauv ib puag ncig mus txog 1177 degrees, tshav kub thiab corrosion resistant alloys, thiab muaj zoo kuj rau intergranular corrosion, kev nyuaj siab corrosion cracking thiab kub halogen corrosion. ; Anti-oxidation kev ua tau zoo, kub thiab txias ua kev ua tau zoo, tsis tshua muaj kub txhua yam kev ua tau zoo, txias thiab kub qaug zog ua haujlwm. Nws muaj lub zog siab ntawm 650 degree, zoo formability thiab yooj yim vuam. Feem ntau siv nyob rau hauv chav cav, dej rhaub, nuclear fais fab nroj tsuag txias; caustic soda thiab VCM ntau lawm; pulp thiab ntawv kev lag luam.

Cov yam ntxwv ntawm Incoloy 800 alloy

(1) Raws li ASME tus qauv, nws muaj lub zog tsim muaj zog thaum thov ntawm 899 degree;
(2) Lub raj siv tau ntawm qhov kub thiab txias hauv qab 982 degree;
(3) Tseem muaj oxidation tsis kam ntawm 1038 degree;
(4) Ua rau chloride ion corrosion.

Daim ntawv thov feem ntau ntawm 800 alloy yog cov ntawv siv kub 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 hluav taws xob thiab cov chaw tsim hluav taws xob nuclear. Cov ntsiab lus siab ntawm chromium thiab npib tsib xee ua rau 800 series alloys muaj kev tiv thaiv zoo rau oxidation thiab carbonization.

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 nyob 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.
