Dab tsi yog qhov txawv ntawm nickel alloy C22 thiab hastelloy C276?
Hastelloy C22 yog dab tsi?
Hastelloy c22 yog ib qho austenitic alloy paub txog nws lub peev xwm los ua haujlwm hauv cov xwm txheej hnyav uas yuav tsum tau ua kom muaj zog tiv taus kub thiab corrosion. Nws yog feem ntau siv thaum lwm cov khoom siv hluav taws xob tiv thaiv hluav taws xob, xws li duplex alloys, tsis ua tau raws li cov neeg siv khoom xav tau ntawm daim ntawv thov.
Nyob rau theem molecular, nws yog tsim los ntawm nickel, molybdenum, tungsten thiab chromium.
Hastelloy C22 siv rau dab tsi?
Raws li tau hais los saum toj no, Hastelloy tau muab cais ua cov hlau tsis muaj cua sov. Qhov no tso cai rau koj los ua kom zoo dua ntawm kev tshuaj ntsuam xyuas / pom muaj peev xwm ntawm woven hlau mesh ntawm qhov kub txog li 1250 degree F (676 degree ).
Tsis tas li ntawd, Hastelloy cov tshuaj muaj pes tsawg leeg tiv thaiv oxidation ntawm qhov kub thiab txias. Nyob rau hauv lem, koj yuav pom tias qhov nto ntawm Hastelloy woven mesh yuav tsis tshua pom discoloration.
Tam sim no, nyob rau hauv cov nqe lus ntawm corrosion kuj, Hastelloy yog siv thaum pitting yog ib qho kev txhawj xeeb. Qhov no yog qhov tshwj xeeb tshaj yog thaum sib koom ua ke cov qib qib acids thiab alkalis rau hauv woven hlau mesh.
Hastelloy C276 yog dab tsi?
Hastelloy c276 yog ib qho tshwj xeeb woven hlau mesh alloy tsim los muab ntau yam corrosion kuj superior rau feem ntau zoo sib xws alloys. Nws yog dav paub txog nws formability, ua tau kub thiab txias tsim nrog tus txheeb ze yooj yim.
Chemically, Hastelloy yog tsim los ntawm manganese, carbon, nickel, hlau, silicon, chromium thiab molybdenum.
Hastelloy C276 siv rau dab tsi?
Hastelloy yog ib qho nrov hlau mesh alloy haum rau kev siv tshuaj rau pem hauv ntej ntawm qhov kub txog li 1900 degree F (1037 degree). Qhov tseeb, nws tiv thaiv grain ciam nag los txawm tias tom qab vuam.
Qhov no ua rau nws tsim tshwj xeeb rau kev ua tshuaj.
Hastelloy c276 muaj qhov tsis tshua muaj kev tiv thaiv rau cov tshuaj hypochlorite, cov tshuaj chlorine dioxide thiab chloride gases. Nws kuj ua haujlwm thaum ntsib ferric chloride thiab tooj liab chloride.
Qhov txawv ntawm Hastelloy C22 thiab C276 yog dab tsi?
Thawj qhov uas yuav tsum nco ntsoov thaum muab piv rau Hastelloy c22 rau Hastelloy c276 yog tias c22 muaj kev xav tau ntau dua rau kev xeb, tshwj xeeb tshaj yog pitting thiab crevices. Qhov no feem ntau yog vim Hastelloy c22 muaj cov ntsiab lus chromium ntau dua li Hastelloy c276.
Yog li, yog tias oxidation yog ib qho kev txhawj xeeb, Hastelloy c22 yog qhov kev xaiv zoo tshaj plaws. Tau hais tias, ob qho tib si alloys muaj cov khoom zoo sib xws hais txog kev txo cov hlau oxides.
Tab sis yuav ua li cas koj ua Hastelloy mesh uas yog rau koj cov txheej txheem?
Ib qho txiaj ntsig tseem ceeb ntawm Hastelloy c22 piv rau Hastelloy c276 yog nws txoj kev ua kom zoo dua. Raws li tau hais los saum no, qhov no suav nrog kev txhim kho kev tiv thaiv rau intergranular corrosion tshwm sim los ntawm huab cua vuam thermal tom qab cuam tshuam.
Txawm hais tias cov alloys no muaj qhov zoo heev, koj cov peev nyiaj yuav yog qhov kev txiav txim siab loj tshaj plaws uas koj tuaj yeem siv tau. Hastelloy c22 xav tau cov khoom siv tsawg dua los tsim, ua rau nws pheej yig dua ntawm ob hom Hastelloy.
Tag nrho cov no hais tias Hastelloy c22 yog ib qho kev txhim kho ntawm Hastelloy c276.
