Stainless hlau li qub yog siv dav hla ib qho kev lag luam dav ntawm kev lag luam {}} roj, tshuaj lom neeg, thiab ntev}-}} kav ntev. Tab sis dab tsi xyov muab stainless hlau nws anti {{4 4} corrosive thiab xeb {{5} {cov khoom tiv thaiv? Cov ntawv no tshawb txog cov hlau metallurgical thiab tshuaj lom neeg tom qab lub durability ntawm stainless hlau li qub.
1. Lub luag haujlwm ntawm chromium hauv stainless hlau
Lub luag haujlwm tseem ceeb ua lub luag hauj lwm rau stainless hlau txoj kev tiv thaiv kab corrosion yog chromium. Feem ntau stainless hlau muaj tsawg kawg10.5% chromium, uas reacts nrog oxygen nyob rau ib puag ncig ua ibNyias, Passive Oxide Txheejsaum npoo. Qhov no tsis pom txheej -} nquag hu uapassivation zaj duab xis{- Ua raws li cov ntaub thaiv npog tawm ntawm ya raws, oxygen, thiab lwm yam corposive. Txawm hais tias qhov saum npoo yog khawb lossis puas, cov chromium hauv cov hlau tam sim ntawd pab rov ua yeeb yaj kiab, kev tswj hwm.
2. Npib tsib xee thiab molybdenum rau kev txhim kho kom tsis kam
Nyob rau hauv ntau stainless hlau qib,tus menyuam yausthiabmolybdenumyog ntxiv los txhim kho kev tiv taus ntau dua ib puag ncig. Nickel ua rau muaj kev ruaj khov ntawm txheej passive, tshwj xeeb tshaj yog nyob rau hauv acidic lossis marine ib puag ncig. Molybdenum, pom nyob rau hauv stainless hlau zoo li 316, muaj kev tiv thaiv zoo tshaj tawm tsamchloride -} induced pitting thiab crevice corrosion, uas yog qhov tseem ceeb hauv dej hiav txwv thiab kev lag luam siv tshuaj lom neeg.
3. Cov pa roj carbon qis txo cov kev xav
Qee hom stainless hlau, xws li304L thiab 316L, tshwj xeeb muaj cov ntsiab lus muaj roj carbon tsawg. Qhov no yog qhov tseem ceeb hauv kev tiv thaiv tus txheej txheem hu uasiab zoo, qhov twg chromium carbides daim foos ntawm cov nplej sib xyaws thaum lub sijhawm ua haujlwm siab, ua rau muaj kev ua kom huv si. Tsawg -} carbon variants pab tswj hwm corrosion tsis kam txawm tias kev fabrication.
4. Tsis - rease refinive nto thiab huv si
Lub cev du, tsis - porous} porous porouse ntawm cov tsis huv, cov kab mob, ua kom nws zoo tagnrho rau kev siv hauv qab hau. Qhov kev nyiam huv no tsis yog ib qho tseem ceeb rau cov zaub mov thiab cov ntaub ntawv ua lag luam tab sis kuj pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau.
5. Tsis tu ncua hla kev mob hnyav
Stainless hlau li qub yog paub kom withstandKev siab siab, huab cua sov heev, thiabKev Siv Tshuaj, ua rau lawv mus -} mus xaiv cov tshuab tseem ceeb. Tsis zoo li cov roj carbon hlau lossis cov khib nyiab hlau li qub, stainless hlau tsis kam xeb yam tsis muaj kev xav tau tshwj xeeb txheej lossis pleev xim txheej. Qhov no cuam tshuam cov nqi kho thiab txuas ntxiv lub neej pabcuam.
6. Passivation thiab txoj kev kho cov nplaim
Txhawm rau txhawm rau txhim kho corrosion tsis kam, cov hlau stainless feem ntau yauv musKev Kho Mob Hla Dhautom qab tsim khoom. Cov txheej txheem no tshem tawm cov hlau dawb los ntawm qhov chaw thiab txhim kho kev txhim kho ntawm cov roj oxide txheej. Muaj qee kis,Kev Hluav Taws XobKuj tseem siv los tsim cov ultra - du nto uas txhim kho kom haum rau kev sib cav thiab xeb.
Cov xeb thiab xeb tsis kam ntawm cov stainless hlau li qub yog qhov txiaj ntsig ntawm kev ua tib zoo saib kev lag luam. Cov ntsiab xws li chromium, npib tsib xee, nrog rau kev tsim khoom zoo thiab cov tshuaj saum npoo av uas yog ib qho ntawm cov ntaub ntawv tsim nyog tshaj plaws hauv kev tsim kho. Rau kev lag luam uas ntseeg tau, huv si, thiab durability tsis {sib ceg li qub, stainless hlau li qub kev ua haujlwm nrog kev saib xyuas tsawg.
