Peb feem ntau pom cov alloys xws li hastellloy c {0}} Thiab hastelloy c -276 ua ke thiab / lossis welded ua ke.
Hastelloy yog ib tus neeg sawv cev ntawm kev corrosion resistant alloy tsev neeg. Ob lub c -22 thiab c -276} yog cov neeg tsev neeg hastelloy. Qhov kev sib thooj no tuaj yeem ua rau tsis meej pem, tab sis c {2}} Tau zoo dua li c {} thiab feem ntau hu ua c -276.
Qhov ntau dua cov ntsiab lus chromium ntau dua hauv c {0}} muab nws zoo dua corrosion tsis kam nyob rau hauv oxidizing kev pabcuam lub neej ntawm cov khoom. Hom muaj zog oxidizing xov xwm suav nrog sodium chloride (nacl), hydrochloric acid (HCl) thiab sulfuric acid (h25o4). C -22}}}}}} Txawm cov khoom pov thawj zoo rau cov tshuaj thiab cov pob txha acacic, cov tshuaj acorganic, cov kev daws teeb meem brine dej, thiab dej hiav txwv.
Hastelloy alloy tsev neeg
Hastelloy c {0}} Kev ua kom pom kev ua kom zoo dua los pitting, thiab kev nyuaj siab corrosion cracking piv rau hastelloy c {1}}.
Ob lub c -22 thiab c -276}}} Tau sim rau pitting thiab crevice corrosion hauv oxidizing media. C -22} Tau pom tias ua kom muaj kev tiv thaiv zoo dua. However, C-22 and C-276 perform equally well in reducing environments. Txo cov neeg sawv cev suav nrog oxalic acid (c2h2o4), formic acid (hcooh), thiab phosphorous acid (h2po4).
Muaj pes tsawg leeg thiab cov khoom
Hastelloy C276 thiab C22 yog ob qho tib si kev ua haujlwm siab npib tsib xee-chromium-molybdenum alloys, tab sis lawv cov kev sib txawv txiav txim siab lawv cov peev txheej. Piv rau hastcelloy c22, hastelloy c276 muaj cov ntsiab lus tsawg dua thiab cov ntsiab lus chromium qis dua. Tsis tas li ntawd, hastelloy c276 tseem muaj cov ntsiab lus molybdenum siab dua li Hastelloy C22. Cov kev sib xyaw sib txawv txawv cuam tshuam rau lawv cov khoom lag luam corrosion, cov khoom siv tshuab, thiab ua tau zoo. Cov ntsiab lus Chromium ntau dua hauv Hastelloy C22 txhim kho nws cov ntsiab lus corrosion, thaum lub siab molybdenum cov ntsiab lus hauv Hastelloy C276 muab nws zoo tshaj plaws corrosion tsis kam thiab pitting ib puag ncig.
Tseem ceeb pitting thiab tseem ceeb crevice corrosion tawm tsam kub
Corrosion Resistance sib piv
Ob leeg hastelloy C276 thiab C22 Exeel hauv corrosion tsis kam, tab sis lawv ua txawv nyob rau hauv ib puag ncig sib txawv. Hastelloy C276 excels nyob rau hauv oxidizing ib puag ncig, xws li muaj nitric acid thiab chlorine, nrog cov corrosion zoo nkauj, thiab kev nyuaj siab corrosion tawg. Qhov no ua rau nws xaiv rau kev ua yeeb yam rau kev ua haujlwm, roj thiab roj thiab hluav taws xob kev lag luam. Ntawm qhov tod tes, hastelloy c22 ua tau zoo hauv kev txo ib puag ncig xws li hydrochloric thiab sulfuric acids. Nws lub peev xwm tiv thaiv cov xwm txheej hnyav no ua rau nws xaiv qhov zoo tshaj plaws rau kev siv cov kev tiv thaiv corrosion yog qhov tseem ceeb.
Kev ua haujlwm kub siab
Hastelloy C276 Me Me Outperforms Hastelloy C22 Hais txog kev ua tau zoo siab. Hastelloy C276 tuaj yeem tiv taus kub txog 1900 degree F (1037 degree), thaum Hastelloy C22 tuaj yeem tiv taus txog 1250 degree f (676 degree). Ntau dua thermal ruaj khov thiab ua rau cov noob qoob loo nag los ua kom Hastelloy C276 Pom kev xaiv nrov rau kev siv hauv qhov chaw kub kub. Cov khoom no yog ib qho tseem ceeb nyob hauv kev lag luam uas cov khoom yog kis tau kub siab, kom ntseeg tau tias cov khoom siv lub neej thiab kev ntseeg tau hauv cov xwm txheej zoo li no.
Cov Khoom Siv Neeg Kho Tshuab thiab Kev Siv
Ob leeg hastelloy C276 thiab C22 muaj cov cuab yeej zoo heev, suav nrog lub zog siab, ductility, thiab tawv. Hastelloy C276 muaj me ntsis siab dua cov txiaj ntsig lub zog thiab lub zog kawg tensile muaj zog dua hastelloy C22. Txawm li cas los xij, haastelloy c22 muaj qhov firability zoo dua thiab weldability, ua rau nws xaiv qhov uas xav tau ntawm cov duab thiab vuam. Cov khoom siv no ua rau ob lub alloys haum rau ntau cov ntawv thov, suav nrog kev ua tshuaj lom neeg, roj thiab roj, lub zog loj, thiab cov roj hluav taws xob, thiab aerospace. Qhov kev xaiv ntawm ob feem ntau nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov, xws li qhov xav tau rau ntau dua corrosion tsis kam los yog ua kom zoo dua.
