Al6xn (tsis muaj n08367)Yog tus neeg siv hluav taws xob zoo nkauj uas tsis muaj zog rau nws qhov tshwj xeeb tiv taus chloride corrosion, suav nrog pitting xeb, thiab kev nyuaj siab corrosion tawg.
AL6XN is the gap between stainless steel and nickel alloys, providing a cost-effective solution for corrosive environments. Nws muaj pes tsawg leeg suav nrog cov chromium siab (20 {{}} 22%), thiab nickon%), thiab nickionine (0.18)
Cov ntawv thov raug yog suav nrog kev ua yeeb yam siv, FLUE GAS Desulfurization (FGD) tshuab, cov nroj tsuag desalination, thiab lub zog nuclear lub zog infrastructure.
ASTM A312 Cov Ntsiab Lus Tseem Ceeb rau Al6xN Kav
ASTM A312 specifies seamless thiab welded oweneritic stainless hlau leeg rau siv nyob rau hauv high- kub thiab corrosive ib puag ncig. Rau al6xn (uns n08367) tubing, tus qauv no cuam tshuam txoj hlua khi uas yuav tsum tau ntawm qhov ntev, kev ua kom ntev, thiab kuaj. Cov ntsiab lus tseem ceeb muaj xws li:
Cov Khoom Siv Qib: Tsis yog N08367 (cim raws li "al6xn" lossis "incoloy 25-6hn").
Daim ntawv foos: Seamless tubing (kub extrusion / cong drawtion) lossis welded tubing (siv Tiging / ntshav / ntshav vuam).
Qhov loj me: Txoj kab uas hla ciam los ntawm 1/8 nti mus rau 48 ntiv tes, Phab ntsa thickness concness (piv txwv li, sch5s rau Sch80)
Xaus kev kho mob: beveled (rau vuam) lossis tiaj tus kawg, nrog kev tiv thaiv kev tiv thaiv lub kaus mom.

254 smo vs al6xn
Tshuaj lom neeg sib txawv
Cov tub ntxhais sib txawv ntawm ob qho lus dag hauv lawv cov lus tsib caug xyoo {}
Vim nws cov ntsiab lus muaj tsib ntau dua, Al {{1xn kev ua kom muaj zog ntawm cov huab cua sov, nrog rau nws cov ntsiab lus ntawm cov dej sov ruaj khov rau nws ruaj khov.
Corrosion Kuj
Ob qho tib si nthuav tawm zoo ib yam li pitting thiab crevice corrosion. Hauv feem ntau chloride ib puag ncig, lawv cov kev ua xeb yog qhov tseem ceeb sib npaug.
Txawm li cas los xij, vim 254SMO muaj kwv yees li 0.7% tooj liab, thaum Al-6xn muaj cov ntsiab lus tooj liab qis dua, cov av me me tsis kam ua rau hauv dej hiav txwv Corrosion Corrosion.
Cov khoom siv neeg kho tshuab thiab siab -} sov daim ntawv thov
Nyob rau hauv cov nqe lus ntawm cov tshuab muaj zog, al-6xn feem ntau ua kom muaj zog me ntsis siab dua. Qhov no yog feem ntau yog ntaus nqi rau nws cov ntsiab lus npib tsib xee thiab cov txiaj ntsig nitrogen, ua rau muaj zog ntawm lub zog thiab lub zog tensile uas muaj kwv yees li 5% rau 10% siab dua 254SMO.
Nyob rau hauv high -} qhov kev siv dej txias, raws li Asme Specifications, Al-6xn raug pom zoo rau 254smo yog kwv yees li 371 degree.
Machinability thiab tus nqi
Txij li thaum Nickel yog ib qho ntawm cov khoom kim tshaj plaws hauv cov khoom siv tshwj xeeb uas tsis muaj nqi, nrog nws tus nqi qis dua {% molybdenum stainless hlau xaiv.
Txawm li cas los xij, 254smo muaj kev tsis zoo machinity. Al-6xN, ntawm qhov tod tes, tau zoo dua kub ua haujlwm thiab muaj kev kho kom txias, ua rau nws yooj yim dua los tsim cov khoom seem.
Cov Qauv thiab Ntawv Pov Thawj & Kev Lag Luam Kev Lag Luam
Hais txog cov qauv kev lag luam thiab cov ntawv pov thawj, 254smo tau dav nrog cov qauv hauv ntiaj teb loj, suav nrog cov qauv Asmeskas (en), thiab nyiam kev ua lag luam muaj kev lag luam zoo heev.
Thaum Al-6xn tseem muaj nyob hauv Asmeskas cov qauv, nws cov kev pab them nqi hauv European tus qauv yog tsawg. Hauv kev lag luam nrog cov kev nyab xeeb heev, xws li roj thiab roj thiab tshuaj lom neeg cov qauv thiab tuaj yeem siv rau hauv cov acth acidic ib puag ncig.
Hauv kev siv cov tswv yim, 254smo ua lub luag haujlwm tseem ceeb hauv dej hiav txwv desalination thiab fluulfurization tshuab vim nws zoo heev- ua hauj lwm zoo.
Al - 6xn, nrog nws lub zog siab dua, muaj ntau txoj kev ruaj khov rau cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob thiab ntau dua xav tau cov khoom siv.
