Ob lub ntsej muag zoo tshaj plaws hauv kev ua lag luam, alloy 400 thiab hastellloy c, tau khwv tau lub koob npe nrov rau lawv cov kev ua tau zoo hauv kev ua haujlwm hnyav. Thaum ob qho tib si yog kev nyiam, lawv muaj cov yam ntxwv tshwj xeeb uas tuaj yeem cuam tshuam rau kev txiav txim siab. Hauv no tus ncej blog, peb yuav tshawb txog qhov sib txawv ntawm alloy 400 thiab haastelloy c, muab cov kev pom zoo muaj txiaj ntsig los pab koj xaiv qhov kev xaiv paub.
Dab tsi yog qhov txawv ntawm alloy 400 thiab hastellloy c?
Corrosion-resistant alloys ua ib lub luag haujlwm tseem ceeb hauv kev tswj hwm qhov kev ntseeg tau thiab cov khoom siv nyob hauv ntau yam kev lag luam xws li kev lag luam, tshuaj lom neeg, thiab petrochemical. Cov kev sib cav saum toj kawg nkaus hauv daim teb no yog alloy 400 thiab hastellloy c, ob leeg uas tau pom dav rau lawv cov kev ua tau zoo hauv cov chaw hnyav. Hauv no blog ncej, peb yuav delve rau hauv qhov sib txawv ntawm ob alloys los pab koj xaiv cov kev xaiv rau koj cov ntawv thov.
Composition:
Alloy 400, tseem hu ua Monel 400, yog tus npib tsib xee-tooj liab uas muaj cov nickel feem ntau ({%) thiab tooj liab ({4 4}}%). Nws tseem muaj cov hlau me me, manganese, carbon, thiab silicon. Hastelloy C, ntawm qhov tod tes, yog tsev neeg ntawm cov alloys uas muaj cov npib tsib xee, thiab chromium, nrog cov khoom sib txawv, nrog cov qib tshwj xeeb (piv txwv li Hastelloy C276). Lub cim sib xyaw ntawm cov alloys muab lub hauv paus rau lawv cov khoom sib piv.
Corrosion Kuj:
Ob alloy 400 thiab Hastelloy C muaj zoo heev corrosion tsis kam, ua rau lawv zoo tshaj rau cov ntawv thov hauv kev xeb thiab kev txhoj puab. Alloy 400 cov khoom pov thawj tshwj xeeb tsis kam rau ntau yam ntawm cov neeg sawv cev ntawm cov neeg sawv cev, acids, thiab alkalis. Cov cuab yeej no ua rau nws xaiv rau kev xaiv marine thiab cov cuab yeej siv nthuav tawm cov kev daws teeb meem. Hastelloy C, ntawm qhov tod tes, muaj cov ntsiab lus siab molybdenum thiab chromium cov ntsiab lus, suav nrog sulfuric acids, xws li cov tshuaj hydrochloric acid, thiab chloride daws. Raws li qhov tshwm sim, hastelloy c feem ntau yog nyiam hauv kev ua lag luam tshuaj thiab petrochemical uas raug rau cov tshuaj muaj ntshav hnyav yog ib qho.
Lub zog:
Nyob rau hauv cov nqe lus ntawm lub zog, hastelloy c feem ntau zoo dua rau alloy 400. Cov neeg siv hluav taws xob siab dua thiab cov neeg siv hluav taws xob siab dua, muab cov khoom siv hluav taws xob siab dua ntawm cov khoom kub. Hauv kev sib piv, alloy 400 yog qis dua hauv lub zog dua li haastelloy C tab sis tswj hwm nws rau qee cov ntawv thov uas xav tau thiab yooj yim ntawm cov fabrication.
Nqi:
Txij li thaum alloy 400 muaj ob lub npe npib thiab tooj liab, nws yog qhov ua tau zoo dua thaum piv rau ntau qib c uas muaj ntau dua npib, molybdenum, thiab chromium cov ntsiab lus. Tus nqi sib txawv ntawm cov alloys tuaj yeem yog qhov tseem ceeb hauv kev xaiv cov khoom siv tau rau ib qho haujlwm, tshwj xeeb tshaj yog thaum muaj kev xaiv cov nplai thiab cov nyiaj txiag.
Cov Ntawv Thov:
Qhov kev xaiv ntawm Alloy 400 thiab hastellloy c feem ntau yog nyob ntawm cov kev tseev kom muaj. Alloy 400 tau siv dav hauv cov neeg ua haujlwm ua engineering, siv tshuaj chemical, khoom siv tshuaj lom neeg, thiab ib qho kev lag luam tshuaj lom neeg vim nws txoj kev tiv taus dej hiav txwv thiab ntau cov acids. Ntawm qhov tod tes, hastellloy C yog haum rau cov ntawv thov nrog cov muaj zog muaj zog, ib puag ncig phem, thiab cov xwm txheej kub. Nws yog dav siv hauv kev ua tshuaj lom neeg, tswj kev qias tuaj, thiab roj thiab roj kev lag luam.
Lwm yam sib txawv:
Ntxiv nrog rau cov kev sib txawv saum toj no, alloy 400 daim ntawv qhia kev ua yeeb yam magnetic cov khoom, thaum haastelloy c tsis. Cov khoom sib nqus ntawm alleoy 400 tseem ceeb heev hauv qee cov kev siv uas hlau nplaum cuam tshuam yog kev txhawj xeeb.
