304 stainless hlau yog kev lag luam thiab siv tau, ua tau raws li kev xav tau txhua hnub; 316 muaj kev tiv thaiv corrosion zoo tshaj vim nws cov ntsiab lus molybdenum, ua rau nws haum rau siab - ntsev thiab siab - av noo ib puag ncig. Rau cov tsev neeg zoo tib yam, 304 txaus, thaum 316 yuav tsum raug txiav txim siab rau cov ntawv thov tshwj xeeb.
Stainless hlau qib 304 thiab 316yog ob qho khoom siv hauv lub neej niaj hnub, dav siv hauv chav ua noj, kev tsim kho, khoom siv kho mob, thiab lwm yam. Ntau tus neeg xav paub thaum xaiv: Dab tsi yog qhov txawv ntawm ob cov ntaub ntawv no? Qhov twg zoo dua rau lawv cov kev xav tau? Hauv qab no yog ib qho kev sib piv kev soj ntsuam raws li qhov muaj pes tsawg leeg, kev ua tau zoo, thiab cov xwm txheej siv tau.
1. Kev sib xyaw ua ke
Thawj qhov sib txawv ntawm cov qib stainless hlau304 thiab 316nyob rau hauv lawv cov alloy muaj pes tsawg leeg. 304 stainless hlau muaj 18% chromium thiab 8% npib tsib xee, yog li nws lub npe hu ua 18/8 stainless hlau. 316 stainless hlau ntxiv 2% molybdenum rau lub hauv paus muaj pes tsawg leeg thaum tuav cov ntsiab lus ntau dua nickel (kwv yees li 10%). Kev suav nrog molybdenum ua rau muaj txiaj ntsig zoo rau 316 qhov kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv siab - ntsev, siab - av noo, los yog acidic ib puag ncig.
2. Corrosion Resistance piv
304 muaj kev tiv thaiv corrosion txaus rau txhua hnub ib puag ncig xws li cov kais dej thiab cov tshuaj ntxuav me me acidic / alkaline. Txawm li cas los xij, 316 cov ntsiab lus molybdenum muab kev tiv thaiv zoo rau cov tshuaj chlorides (xws li dej hiav txwv, ntsev tsuag) thiab cov kua qaub muaj zog. Piv txwv li, nyob rau hauv cov cheeb tsam ntug hiav txwv dej los yog kev lag luam ua zaub mov, 316 yog tsis tshua muaj pitting corrosion los yog xeb me ntsis.
Lus Nug: Puas yog 316 tsim nyog rau cov khoom siv hauv tsev?
Teb: 304 zoo kawg nkaus rau kev siv hauv tsev. Xav txog 316 yog tias koj cov khoom siv yuav nyob rau lub sijhawm ntev nrog cov khoom noj muaj ntsev (xws li cov khoom qab zib) lossis nquag raug rau cov tshuaj chlorine- raws li cov tshuaj ntxuav.
3. Mechanical Properties
Ob qib qhia zoo sib xws lub zog thiab hardness. Txawm li cas los xij, 316 muaj kev ruaj ntseg me ntsis hauv siab - qhov kub thiab txias vim nws cov ntsiab lus alloy siab dua. Piv txwv li, nws ua kom pom kev nkag siab zoo dua thaum raug kub hnyiab tas li saum 80 degree. Txawm li cas los xij, qhov sib txawv no feem ntau tsis pom zoo rau cov txheej txheem cookware lossis cov qauv hauv tsev.
4. Tus nqi sib txawv
316 nqa cov nqi tsim khoom ntau dua li 304, feem ntau hais kom tus nqi 20% -30% hauv cov nqi lag luam. Piv txwv li, ib tug 316 stainless hlau thermos ntawm zoo tib yam specifications yuav raug nqi RMB 50-100 ntau tshaj ib tug 304 sib npaug. Seb tus nqi them no puas tsim nyog yog nyob ntawm qhov kev siv tshwj xeeb. Piv txwv li, cov khoom siv hauv chaw soj nstuam lossis cov khoom siv hauv hiav txwv feem ntau muab qhov tseem ceeb rau 316 rau nws cov khoom zoo, thaum 304 tseem yog qhov kev xaiv pheej yig dua rau cov khoom siv hauv tsev txhua hnub.
5. Cov ntawv thov pom zoo
- 304 Daim Ntawv Thov Kev Tsim Nyog: Cov rooj tog zaum hauv tsev (xws li, cov txee, cov khoom siv tes ua), cov khoom siv hauv tsev txhua hnub (cov lauj kaub, tais, dab dej), architectural tiav hauv qhov chaw qhuav.
- 316 Daim Ntawv Thov Kev Tsim Nyog: Ntug tsev sab nrauv sab nrauv, cov khoom siv tshuaj lom neeg lossis cov khoom siv kho mob, cov khoom raug hws los yog ntsev (xws li, saib cov hlua)
6. Yuav paub qhov txawv 304 thiab 316 li cas?
Cov neeg siv khoom tuaj yeem txiav txim siab ua ntej siv cov txheej txheem no:
- Kos Npe: Cov khoom raug cai yuav raug sau npe "SUS304" lossis "SUS316."
- Chemical Reagent Testing: 316 reacts qeeb dua rau acidic reagents, tab sis yuav tsum muaj kev tuav haujlwm.
- Magnetic test: Ob leeg yog austenitic stainless hlau thiab feem ntau tsis yog -magnetic. Txawm li cas los xij, ua tiav 304 tuaj yeem pom me ntsis hlau nplaum. Txoj kev no tsuas yog siv rau kev siv xwb.
7. Kev ceev faj txog kev tu
Ob leeg304 thiab 316yuav tsum tau ntxuav tsis tu ncua los tiv thaiv corrosion:
- Tsis txhob raug cov kua qaub los yog alkalis ntev ntev (piv txwv li, tshuaj dawb).
- Qhuav tam sim ntawd tom qab ntxuav kom txo cov dej seem.
- Tsis txhob txhuam nrog cov khoom tawv zoo li cov ntaub plaub hlau los tiv thaiv kev puas tsuaj rau cov oxide txheej.
Xaus
Hauv cov ntsiab lus, ob qho tib si304 thiab 316muaj qhov zoo sib txawv, thiab tsis yog qhov zoo tshaj plaws. Kev xaiv yuav tsum yog nyob ntawm kev siv ib puag ncig, pob nyiaj siv, thiab cov kev xav tau tshwj xeeb. Rau kev siv hauv tsev, 304 muaj txiaj ntsig zoo dua rau cov nyiaj, thaum 316 raug pom zoo rau cov chaw tshwj xeeb. Thaum yuav khoom, xyuas kom meej tias cov ntaub ntawv yog los ntawm cov chaw muag khoom muaj npe nrov thiab ua raws li cov qauv tsim nyog.
