Qhov twg stainless hlau yog qhov zoo tshaj-304, 316, lossis 430?
Qhov twg stainless hlau yog qhov zoo tshaj-304, 316, lossis 430?
Qhov zoo tshaj plaws ntawm tus kheej stick yog nyob ntawm cov ntaub ntawv tshwj xeeb thiab kev xaiv ua kom haum rau cov tubrog phem lossis cov khoom noj muaj txiaj ntsig zoo tshaj plaws thiab feem ntau siv rau kev zoo nkauj lub hom phiaj lossis hauv cov chaw muaj kev ywj pheej tsawg.
Yog SS 430 zoo dua li SS 316?
316 SS Muaj cov tshuaj lom neeg zoo tshaj plaws hauv ntau cov ntawv thov, tshwj xeeb yog thaum muaj cov ntsev thiab muaj zog acidic sib txuas zoo li txiv qaub lossis kua txiv. Txawm li cas los xij, rau cov chaw tsim khoom noj khoom haus yuav tsum muaj cov khoom noj muaj kuab-resistant cov khoom noj-qib hlau rau lawv cov txheej txheem ntau lawm, 430 yog ib txoj kev xaiv zoo, tsawg.
Raws li koj tuaj yeem paub, lub sij hawm "stainless hlau" tsis xa mus rau ib qho alloy, tab sis yog ib pawg ntawm cov ntsiab lus chromium tsawg kawg 10.5%. Txhawm rau txhim kho cov hlau cua sov thiab corrosion tsis kam, lwm cov ntsiab lus feem ntau ntxiv rau nce cov ntsiab lus chromium. Qhov no txhim kho cov hlau cov khoom siv thiab ua cov yam ntxwv.
Niaj hnub no, muaj ntau ntau qib ntawm cov qib ntawm cov hlau uas tsis muaj zog los paub qhov txawv sib txawv. Cov qhab nia no feem ntau pom los ntawm cov koom haum tswj hwm hauv kev lag luam hlau. Txawm li cas los xij, muaj peb feem ntau cov kev faib tawm los txheeb xyuas cov hlau stainless.
Hom 304: Cov hlau no muaj nyob rau ntau yam khoom cov khoom, yog yooj yim rau ntaub thiab daim ntawv, thiab muab cov tshuaj tiv thaiv corrosion.
Hom 304 stainless hlau yog inherently tsis-sib nqus thiab tiv taus ntau cov kua qaub, thiab ntau cov organic thiab inorganic tshuaj. Nws yog siv nyob rau hauv kev tsim cov khoom noj khoom noj, ntim khoom siv cov khoom siv lag luam, chaw ua lag luam, vov tsev, cladding, thiab qhov rooj.
Hom 316: Cov hlau no zoo heev li hom 304, txawv feem ntau hauv kev ntxiv ntawm Molybdenum (3%). Qhov no ua rau hom 316 tiv taus corrosion los ntawm calcium-sodium brines, phosphoric acid, hypochlorite daws teeb meem, thiab sulfurous acid.
Hom 316 yog siv dav hauv kev lag luam kho mob thiab tshuaj rau kev tsim cov khoom siv kho mob. Nws tseem dav siv nyob rau hauv kev haus dej haus thiab dej khib nyiab, kev tsim kho, thiab cov ntawv thov marine.
Ntaus 430: Cov hlau no feem ntau siv hauv chav ua noj thiab tableware. Nws muaj tsis muaj Molybdenum lossis npib tsib xee, ua rau nws tsis tshua muaj nqi ntau dua li ntau hom 304 thiab 316 muaj qhov tsis zoo rau cov qauv tsim los yog kev thauj khoom zoo.
Zoo li hom 304, Ntaus 430 yog ib qho ntawm cov nyiam tshaj plaws thiab muaj cov qauv stainless hlau me me. Txawm li cas los xij, ntaus 430 yog kev lag luam ntau dua vim tias nws tsis muaj kev cuam tshuam corrosion ntawm 300 series. Nws tseem siv rau hauv kev tsim cov kav dej muaj, tshuab ntxhua khaub ncaws, thiab tsheb kho tsheb.
Uas stainless hlau yog qhov zoo tshaj?
Raws li tau hais ua ntej, ntaus 430 stainless hlau yog qhov haum rau cov ntawv thov tsawg-, xws li cryware, xws li cryware thiab lwm yam khoom siv. Yog tias koj tab tom nrhiav rau cov hlau zoo dua qub qub, koj yuav tsum xaiv hom 304 lossis hom 316 stainless hlau. Muaj tsis muaj ntau qhov sib txawv ntawm ob, tab sis cov ntsiab lus hauv qab no tuaj yeem pab koj xaiv koj li:
Ib puag ncig: ob hom 304 thiab hom 316 stainless hlau tuaj yeem tiv taus cov chaw muaj kev xeb heev. Txawm li cas los xij, hom 316 Stainless hlau yog qhov haum ntau rau cov ntsev, acid, thiab chlorides vim tias nws muaj molybdenum, uas muab ntau dua corrosion tsis kam.
Kub: rau qhov chaw kub-ib puag ncig (< 454°C and > 843°C), Type 316 stainless steel is required.
Nyiaj txiag: Hom 304 stainless hlau yog qhov tsis tshua kim dua hom 316 stainless hlau. Yog li ntawd, yog tias koj tab tom nrhiav kev xaiv tus nqi-zoo, hom 304 stainless hlau yog qhov xaiv pom.
Yog li, qhov zoo tshaj plaws stainless hlau qib yog hom 316. Txawm li cas los xij, nws tus nqi siab ua kom tau ntau yam uas nyiam ntau yam.
Gnee steel tshwj xeeb hauv kev tsim khoom thiab muag ntau ntawm cov khoom lag luam ntau ntawm stainless hlau, suav nrog 304, 904, 90205 duplex, thiab 316L stainless hlau. Gnee Steel cov khoom tau siv dav hauv chav ua noj, Aerospace, tshuaj lom neeg, hluav taws xob, thiab lub zog nuclear, thiab lub zog nuclear, thiab hluav taws xob tsis zoo ntxiv.
