Stainless hlau 304 vs . 430}: ua kev xaiv txoj cai rau ntev- sij hawm reliability

Xaiv ntawm qib304 thiab 430 stainless hlauYuav tsum muaj kev nkag siab meej txog lawv cov txiaj ntsig sib txawv rau cov ntawv thov tshwj xeeb. Los ntawm qhov kev xav ntawm cov txheej txheem stainless hlau, peb tsom xam cov khoom siv tshuaj lom, thiab cov xwm txheej sib xyaw, thiab cov txheej txheem kev sib haum xeeb kom paub cov yam ntxwv xaiv thiab cov lus qhia meej.

Cov khoom siv yam ntxwv Txheej txheem cej luam

Tshuaj lom neeg tshuaj lom neeg: Nickel cov ntsiab lus txhais lus Corrosion Kuj

Lub corrosion tsis kam ntawm 304 Stainless HlauStems los ntawm cov zaj duab xis passive txaus tsim los ntawm nws 8% -10.5% npib tsib siv cov ntsiab lus ua ke nrog 18% chromium. Nyob rau hauv ib txoj kev ua kom dej tob hauv qab hiav txwv, 316L stainless hlau) ua tiav ib puag ncig corrosive (6 mg / kg h₂, thiab 7,592-16,085 mg / l clr⁻. Raws li tib qho kev mob, qib 304, los ntawm kev kho mob corrosion incocol, ua tiav tau nyiaj li 15 xyoo txo ​​rau cov pa roj carbon hlau.

Cov qauv ferritic ntawm 430 stainless hlau muaj 16% -18% chromium cov ntsiab lus tsis muaj txiaj ntsig, txo cov nqi ntawm kwv yees li 30%. Txawm li cas los xij, qhov no los ntawm cov nuj nqis ntawm corrosion tsis kam. Ib qho khoom noj ua khoom noj cov xim av muaj xeb tshwm sim ntawm cov phab ntsa sab hauv ntawm 430 cov ntim khoom lom zem tom qab peb pab. Tom qab hloov mus rau qib 304, cov cuab yeej ua raws li FDA cov kev xav tau rau cov ntawv thov hauv kev noj zaub mov.
 

Lub cev lub cev: Toffness vs. hardness -}} daim ntawv thov cov ntaub ntawv xaiv

Cov qauv Austenitic ntawm 304 muab ntsuas hluav taws xob sib npaug: 520 MPa tensile lub zog, ntau dua 40% thiab quenched hauv kua ammonia ntawm - 196 degree. Cov Cuab Yeej Siv Kho Mob Tshaj Tawm tias 30,000 Cycles tau tawm ntau dua 100,000 Cycles ntawm AutoClave Sauxs, Whereas 430 Cov Hluav Taws Xob Pom Raws Li Kev Ntsuas Zoo Li Cas.

Cov qauv ferritic ntawm 430 tau muab ntau dua hardness (200 hv tiv thaiv (200 hv tiv thaiv 180 hv rau 304) tab sis kev siv lub siab nrog elongation qis dua 25%. Cov yam ntxwv no ua rau nws haum ntau yam kev lag luam hood, nrog cov khoom siv rau 430 tus nqi ua tiav tau sib npaug ntawm kev ua tiav ntawm cov xim ua tiav tom qab kev kho mob.

Daim Ntawv Thov Zaj Dab Tsi: 304 Rau kev sib cuag nrog zaub mov, 430 rau cov ntawv thov dai hniav

Cov xwm txheej yuav tsum tau 304:

Cov Khoom Noj Khoom Haus Sib Txuas Khoom Noj (Raws Li Astm A240 Qib 304 Rau Cov Ntawv Thov Khoom Noj Khoom Haus)

Kev kub siab thiab huab cua siab ib puag ncig kev ib puag ncig (cua sov 16.2 w / min k)

Cov Khoom Siv Kho Mob thiab Khoom Siv Ua Si (hla ISO 10993 Biocompatibility Testing)

Cov teeb meem tshwj xeeb 304 muaj xws li: Cov Khoom Noj Hauv Zis (ASTM A240 Qib (304's Social) (304 hla ISO 10993 biocompatibilation xeem, ua rau nws nyiam rau Txoj kev lis ntshav sawv, cov khoom siv cov khoom siv, thiab cov khoom siv zoo sib xws).

Cov xwm txheej tsim nyog rau 430:

Hniav Luas thiab Cov Ntsiab Lus Architecture (qis dua tus nqi ib cheeb tsam)

Cov cuab yeej siv rau sab nraud (cov khoom sib nqus ntawm cov khoom sib nqus

Qhuav ib puag ncig (ntau dua hardness txo deformation pheej hmoo)

430 yog qhov tsim nyog rau: Cov ntawv thov dai khaub ncaws (chaw muag khoom sib txuas lus ntawm cov khoom noj kom zoo nkauj thiab muaj kev sib tiv tauj (rau kev sib tiv tauj Xwm thiab Shelving tau txais txiaj ntsig los ntawm 430 lub zog hardness thiab txo kev txhawj xeeb tsis zoo).

Cov txheej txheem sib xyaw: Kev tsim cov khoom plig txiav txim siab cov txiaj ntsig tau zoo

304's siab ductility nthuav qhia kev sib tw rau kev sib tw vim yog ua haujlwm tawv. Machining cov ntaub ntawv qhia tau tias 304 yuav tsum tau 40% ntau dua cov rog ntau dua 430, pom zoo carbide tooling nrog 15 m / min txiav ceev. Lub rooj sib tw zoo li kev tshawb fawb pom tias yuav siv hlau 304 tus ntaiv ua kom xaim xaim, thaum ER430 muab tub lim rau 430 lub Cheebtsam txo cov nqi vuam vuam siv 35%.

430 tus qauv ferritic pom tau pom zoo kom muaj cov ntaub ntawv stampying Ib qho kev tso tsheb tawm hauv lub cev paub tseeb tias430 stainless hlau, thaum annealed ntawm 800 degree, qhia 25% txhim kho 25% kev ua kom qaug zog tiv thaiv 70% ntawm tus nqi ntawm 304 daws.

Cov Ntawv Qhia Xaiv

1.Material tus kheej: Tseeb 304 cov Cheebtsam yuav tsum tau cim raws li cov qauv kev hloov pauv, 304 qhia tsis muaj xim AG240 / A27 feem ntau hloov xim av {{liab.
2.Magnnetic teb: 304 feem ntau tsis muaj zog sib nqus tom qab ua haujlwm txias; Ua tiav kev ncua ntawm cov hlau nplaum yuav qhia tias tsis muaj neeg hloov khoom.
3.Qhov kev ntsuas tus nqi tsom xam tus nqi: Lub tsev noj mov kev kawm pom thawj zaug 40% cov nyiaj khaws cia siv 430 tableware, tab sis tom qab peb tus nqi ntau dua li 304 lwm yam tshaj li 154.

Tswv yim ua piv txwv

Los ntawm kev thov kev siv tshuab engineering, tsis muaj meej meej los yog inferiority -}} tsuas haum rau cov xwm txheej tshwj xeeb. Thaum battling corrosive cov tshuaj hauv chav ua noj, 304 stainless hlau ua pov thawj txhim khu kev qha ally; Rau cov khoom siv tes ua lag luam - nkauj zoo nkauj hauv chaw ua lag luam, 430 muaj tus nqi zoo tshaj plaws rau nyiaj. Nco ntsoov: Kev xaiv cov khoom tsis yog kev sib tw zoo nkauj- qhov kev xaiv zoo tshaj plaws yog tus uas haum txoj haujlwm.
