C276 Luj tshib tau zoo heev corrosion tsis kam rau ntau yam ntawm cov kua roj kub thiab muaj kev txo qis hauv cov ntawv thov sulfuric kub thiab hydrochloric.
Kev npaj ntawm cov ntsiab lus nyob rau hauv cov kab lus ntawm cov khoom muaj yuav hais tau li cas cov ntsiab lus cuam tshuam rau ib qho tshuaj. Raws li nws yog nyob rau hauv nruab nrab ntawm lub rooj, peb paub cov khoom siv titanium ua kom muaj peev xwm ntawm cov hlau thiab tsis yog hlau.
Titanium yog lub caij dimorphic nrog cov ntawv hexagonal uas maj mam hloov mus rau hauv lub cev lub voos xwmfab ntawm qhov ntsuas kub ntawm 880?
Hastelloy C-276 alloy tuaj yeem raug rau, kev kub ntxhov-chim siab, thiab cuam tshuam. Txawm hais tias cov alloy yuav ua haujlwm-harden, nws tuaj yeem ua tiav kev sib tw-kos-kos, spun, nias tsim lossis xuas nrig ntaus.
Hastelloy muab kev ua tau zoo heev rau kev txo qis thiab muaj cov oxiding oxidizing corrosive acids, raws li zoo heev kev nyuaj siab corrosion thiab kev tiv thaiv mus rau hauv zos nres.
Hastelloy C-276 muaj nyob rau hauv daim phaj, sawb, lab, xaim, cov yeeb nkab, cov yeeb nkab, flanges, fittings.
Titanium muaj tsawg dua thermal thiab hluav taws xob cuam tshuam piv rau lwm cov hlau, txawm hais tias nws cov khoom pov thawj superconduct cov khoom thaum txias hauv qab 0.49 K Kub (nws qhov kub thiab txias).
Hastelloy C276 Alloy, uncoy, uncloy, 2.4819, yog qhov feem ntau dav siv thiab ntau yam kev tiv thaiv nickel.
Qhov txheej txheem tiv thaiv no ua rau cov titanium los ua ib qho zoo tshaj plaws corrosion-resistant lub keeb kwm - resistant theem zoo¡urlmost zoo li platinum. Cov cuab yeej no ua rau nws muaj cov kua dej muaj zog xws li cov pa roj acid, noo noo, cov kua qaub chloochloric, thiab feem ntau cov organic acids.
Qhov yaj ntawm titanium tuaj yeem tsuas yog tshwm sim hauv qhov chaw ua yeeb yam hauv lub tshuab hluav taws xob xws li lub tshuab nqus tsev.
Titanium tau pom nyob rau xyoo 1791 los ntawm cov lus Askiv thiab pob zeb hauv av Williamist William Gregor. Nws xav tias nws yog qhov sib xyaw. Tom qab ntawd, nws tau muaj npe tom qab lub Titan ntawm Greek mythology los ntawm German yog tus neeg siv khoom lag luam Martin Heinrich Klapros.
Titanium yog kev hloov pauv hlau uas tseem ua tau cov khoom sib thooj hauv nws tus cwj pwm tshuaj, tshwj xeeb tshaj yog nyob rau hauv qis dua li Chrome thiab Vanadium.
Tag nrho cov txheej txheem ntawm vuam ntawm vuam siv tau rau Weld Heel Hastelloy C-276 Alloy, txawm hais tias cov txheej txheem oxyacetylene tsis pom zoo. Cov kev ceev faj tshwj xeeb yuav tsum tau coj mus rau kev ua kom sov ntau dhau.
Titanium, zirconium, thiab silica txhua tus koom nrog thawj pawg hloov pauv hauv lub rooj ntu.
Thermodynamically, titanium yog cov hlau yooj yim vim nws lub peev xwm tsis zoo, thiab nws hlawv nyob rau hauv cov huab cua ntawm qhov ntsuas kub tsawg dua li nws qhov point. Nws tuaj yeem hnov mob nrog cov tshuaj chlorine ntawm 550? C thiab tseem tuaj yeem sib txuas nrog lwm cov roj Halogen A txawm hais tias nws nqus hydrogen.
Titanium yog suav tias yog lub zog hlau nrog lub zog tensile kawg ntawm 434 MPa uas ua rau 63,000 psi uas yog kwv yees sib npaug nrog lub zog ntawm cov qib qis steel alloy.
Qhov no txhais tau tias titanium tuaj yeem siv los ua kev hloov rau stat¡ªa cov txiaj ntsig loj, raws li nws yog 45% sib dua dua li cov hlau. Nws yog ob zaug kom muaj zog li txhuas thiab 60% denser.
Thaum Titanium yog tov nrog lwm cov hlau, cov alloys tuaj yeem ncav cuag lub zog tensile ntau dua 1,400 MPa, uas ua rau psi.
Txawm li cas los xij, Titanium tuaj yeem poob nws lub zog ntawm qhov kub tshaj 430? C vim nws tsis nyuaj li cov qib siab ntawm cov hlau.
Hastelloy qhov tsis kam mus rau cov sulfuric acid ua rau nws ib qho kev xaiv rau kev tiv thaiv ntawm hydrogen sulfide (H2s), feem ntau hu ua? Sur roj.
Qhov no tshwm sim vim tias cov cua kub tshwj xeeb pib nce ntxiv raws li kev hloov pauv kub ntawm 880? C tau mus txog.
Hastelloy C276 Taubhau Welded luj tshib ua kev ua yeeb yam tsis-oxidising thiab cov acids sib xyaw
Kev coj cwj pwm ntawm cov hlau titanium muaj qhov zoo sib xws nrog zirconium thiab silica.
Titanium nyob hauv pab pawg 4 (IVB) ntawm lub rooj ntu, uas txhais tau tias nws yog nyob hauv nruab nrab.
Titanium yog cov lus hais tias cov hlau uas muaj kuab nrog tus lej hauv plab thiab lub zog siab; Nws yog siv rau ntau yam kev siv.
Titanium cov khoom siv thermodynamic tsis pub nws kom yaj nyob rau hauv ib txwm muaj mob thiab tuaj yeem ntes cov hluav taws yog tias cov pa roj oxygen nyob hauv nws ib puag ncig.
C-276 Alloy ib txwm muaj kev daws teeb meem kub-kho thaum muaj 2050¡Ãf (1121¡ÃC) thiab nrawm nrawm. Yog tias ua tau, qhov uas tau ua rau kub-tsim yuav tsum tau daws kev kho mob kub ua ntej fabrication ua zaum kawg lossis kev teeb tsa.
Titanium sai sai pib ua kom hnov mob nrog oxygen lwg me me ntawm ib ncig ntawm 1,200? C, thiab nws tuaj yeem nthuav tawm tib tus cwj pwm ntawm 610? C thaum oxygen yog nyob rau hauv daim ntawv ntshiab.
Titanium tseem yog pawg hlau, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig oxygen.
Titanium coj tus cwj pwm ua rau muaj cov pa oxygen thiab dej, uas txhais tau tias nws tsis hnov cuam tshuam nrog cov pa thiab dej ntawm huab cua sov.
