Stainless hlau 201 feem ntau suav hais tias muaj kev nyab xeeb rau kev sib cuag zaub mov vim nws tsis muaj tshuaj lom thiab tsis nkag mus rau hauv cov zaub mov. Txawm li cas los xij, nws tsis yog feem ntau siv rau cov ntawv thov zaub mov vim nws qhov kev tiv thaiv qis dua piv rau lwm qib stainless hlau zoo li 304 thiab 316.
Feem ntau, cov qib stainless hlau uas feem ntau siv rau cov ntawv thov zaub mov muaj xws li 304, 316, thiab 430. Cov qib no muaj qib siab ntawm chromium thiab / lossis nickel cov ntsiab lus, uas muab kev tiv thaiv corrosion zoo dua thiab ua rau lawv tsim nyog siv rau hauv cov khoom noj. cov khoom siv ua khoom noj, cookware, thiab lwm yam kev siv khoom noj.
Yog tias koj siv stainless hlau rau cov ntawv thov zaub mov, nws yog ib qho tseem ceeb uas yuav tau xaiv cov qib tsim nyog raws li cov kev cai tshwj xeeb ntawm koj daim ntawv thov. Tsis tas li ntawd, kev tu thiab tu kom zoo yuav tsum tau ua raws li kom muaj kev nyab xeeb thiab zoo ntawm cov khoom noj uas tau ua tiav lossis npaj.
Stainless hlau feem ntau yog siv rau hauv kev ua zaub mov thiab kev npaj vim nws tsis kam mus corrosion, yooj yim ntawm tu, thiab tu cev. Txawm li cas los xij, tsis yog txhua qib ntawm stainless hlau yog tsim rau kev siv zaub mov-qib.
01
Stainless hlau 304
Stainless hlau 304 yog cov qib feem ntau siv rau cov khoom noj-qib daim ntawv thov vim nws zoo heev corrosion kuj, kub tsis kam, thiab zoo formability. Nws muaj 18% chromium thiab 8% npib tsib xee, uas muab qhov sib npaug zoo ntawm kev tiv thaiv corrosion, lub zog, thiab kav ntev. Stainless hlau 316 zoo ib yam li 304, tab sis nrog kev sib ntxiv ntawm molybdenum, uas txhim kho nws cov corrosion kuj nyob rau hauv ib puag ncig hnyav nrog cov ntsiab lus chloride siab.
02
Stainless hlau 201
Stainless hlau 201 yog lwm qhov kev xaiv, tab sis nws tsis tshua siv rau cov ntawv thov zaub mov vim nws qis dua corrosion piv rau lwm qib. Txawm hais tias nws feem ntau suav tias muaj kev nyab xeeb rau kev sib cuag zaub mov, nws yuav tsis haum rau cov khoom noj uas muaj kua qaub los yog corrosive ntev.
03
316 stainless hlau
Qhov no muaj kev tiv thaiv corrosion ntau dua li 304, ua rau nws tsim nyog rau kev thov ntau ntxiv xws li cov chaw hauv dej hiav txwv.
04
430 stainless hlau
430 stainless hlau, tseem hu ua 18/0 stainless hlau, yog ib hom ferritic stainless hlau uas tau siv dav hauv ntau daim ntawv thov vim nws pheej yig thiab zoo corrosion kuj.
Cov qib stainless hlau feem ntau siv rau cov ntawv thov zaub mov yog 304, 316, thiab 430. Cov qib no paub txog lawv cov kev tiv thaiv corrosion siab, zoo formability, thiab tu cev. Lawv kuj tau txais kev pom zoo los ntawm cov koom haum tswj hwm xws li US Food and Drug Administration (FDA) rau kev siv hauv kev ua zaub mov thiab kev npaj.
Thaum xaiv cov qib stainless hlau rau cov ntawv thov zaub mov, nws yog ib qho tseem ceeb uas yuav tsum tau xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov, suav nrog cov khoom noj uas tau ua tiav lossis npaj, qhov kub thiab ib puag ncig ntawm daim ntawv thov, thiab qib yuav tsum muaj kev tiv thaiv corrosion. Kev tu kom zoo thiab kev saib xyuas yuav tsum tau ua raws li kom muaj kev nyab xeeb thiab zoo ntawm cov khoom noj uas tau ua tiav lossis npaj.
Thaum 201 stainless hlau yog technically suav hais tias "stainless" vim nws cov ntsiab lus chromium, nws feem ntau tsis pom zoo rau cov ntawv thov zaub mov. Nov yog vim li cas:
Yog vim li cas tsis siv 201 stainless hlau rau zaub mov qib:
- Cov ntsiab lus nickel qis dua: Piv rau cov khoom noj-qib stainless hlau zoo li 304 thiab 316, 201 muaj nickel tsawg dua. Cov ntsiab lus npib tsib xee qis no tuaj yeem tso cov kab nickel rau hauv cov zaub mov, tshwj xeeb tshaj yog nyob rau hauv acidic tej yam kev mob, uas tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv.
- Cov ntsiab lus ntawm manganese ntau dua: 201 muaj ntau cov manganese, uas tuaj yeem nkag mus rau hauv cov zaub mov thiab ua rau muaj kev saj tsis zoo.
- Kev tiv thaiv corrosion: 201 tsis tshua muaj kev tiv thaiv corrosion dua li cov khoom noj khoom haus-qib stainless hlau, tshwj xeeb tshaj yog nyob rau hauv acidic los yog qab ntsev. Qhov no tuaj yeem ua rau pitting thiab xeb, uas tuaj yeem paug cov zaub mov thiab tsim kev phom sij rau kev noj qab haus huv.
Lwm txoj hauv kev rau kev siv zaub mov qib:
- 304 stainless hlau: Qhov no yog cov khoom noj khoom haus tshaj plaws-qib stainless hlau. Nws muaj cov ntsiab lus ntau dua nickel thiab tiv taus corrosion ntau dua, ua rau nws muaj kev nyab xeeb rau cov khoom noj.
- 316 stainless hlau: Qhov no muaj kev tiv thaiv corrosion ntau dua li 304, ua rau nws tsim nyog rau ntau daim ntawv thov xws li marine ib puag ncig.
Xav txog ntxiv:
Yog tias koj tsis paub meej tias cov khoom tshwj xeeb 201 stainless hlau yog cov khoom noj khoom haus, nws yog qhov zoo tshaj rau kev ua yuam kev ntawm kev ceev faj thiab tsis txhob siv nws rau kev sib cuag zaub mov.
Nco ntsoov nrhiav ntawv pov thawj los ntawm cov koom haum muaj koob npe zoo li National Sanitation Foundation (NSF) thaum xaiv zaub mov-qib stainless hlau.
Xav txog qhov tshwj xeeb npaj siv ntawm stainless hlau. Piv txwv li, yog tias nws yuav nyob rau hauv kev sib cuag nrog cov zaub mov los yog nws yuav raug rau acidic los yog ntsev ib puag ncig, ib qib siab stainless hlau zoo li 304 los yog 316 yog pom zoo.
Nco ntsoov, kev nyab xeeb ntawm zaub mov yog qhov tseem ceeb. Los ntawm kev xaiv qhov zoo ntawm stainless hlau rau koj cov kev xav tau, koj tuaj yeem ua kom koj cov zaub mov muaj kev nyab xeeb thiab noj qab nyob zoo.
