410 Stainless hlau raj
410 stainless hlau nta
(1) Lub zog muaj zog;
(2) Zoo heev machinability;
(3) Hardening tshwm sim tom qab kev kho cua sov;
(4) Sib nqus;
(5) Tsis haum rau qhov hnyav corrosive ib puag ncig.
Cov tshuaj muaj pes tsawg leeg ntawm 410 stainless hlau yog tus cwj pwm los ntawm kev ntxiv molybdenum, tungsten, vanadium, niobium, thiab lwm yam khoom raws li kev sib txawv ntawm cov khoom sib txawv ntawm 0.1% -1.0% carbon C thiab 12% -27% chromium Cr.Txij li cov qauv ntawm cov ntaub so ntswg yog ib lub cev-centered cubic qauv, lub zog poob sharply ntawm qhov kub thiab txias.
Qhov sib txawv ntawm 401 stainless hlau thiab 304 stainless hlau
Qhov txawv ntawm 401 stainless hlau thiab 304 yog qhov tuab.304 stainless hlau yog austenitic stainless hlau, 401 series yog martensitic stainless hlau, lub qub tsis sib nqus, tom kawg yog sib nqus.401 yog hom 400 series stainless hlau.Feem ntau hais lus, 304 zoo dua rau xeb thiab corrosion kuj.Hauv qee qhov chaw tshwj xeeb, 401 zoo dua 304. Piv txwv li, qee qhov chaw yuav tsum muaj qib siab dua hauv Is Nrias teb tab sis tsis xav tau xeb zoo., koj tuaj yeem xaiv siv 401 lub sijhawm no.Hauv lub neej txhua hnub, kuj tseem muaj ntau yam uas yuav tsum tau saib xyuas thaum siv cov hlau tsis muaj steel.Piv txwv li, nco ntsoov ua noj lossis khaws cov zaub mov acidic hauv lub lauj kaub hlau stainless thaum siv, txwv tsis pub, cov kua qaub hauv cov khoom noj acidic yuav ua rau qee cov khoom xyaw hauv lub lauj kaub stainless hlau.Nco ntsoov tsis txhob siv stainless hlau los ua noj tshuaj suav tshuaj.Cov tshuaj suav tshuaj suav nrog qee cov khoom xyaw tsis zoo, yog li tsis txhob xaiv cov tais diav no los ua noj.Nyob rau hauv tus txheej txheem ntawm kev siv stainless hlau, nco ntsoov hlawv nws khoob, vim hais tias cov thermal conductivity ntawm stainless hlau pots yog qis dua li ntawm lwm yam ntaub ntawv, thiab cov cua kub conduction kuj qeeb.Kev laus muaj feem cuam tshuam rau lub neej ua haujlwm.
Cov nyhuv ntawm 401 stainless hlau rau tib neeg lub cev
401 stainless hlau tsis muaj kev phom sij rau tib neeg lub cev thiab yog siv dav hauv cov khoom siv tshuaj tiv thaiv corrosion, cov tais diav, khoom siv kho mob, rooj tog zaum, rooj tog, thiab lwm yam.401 stainless hlau yog qib zaub mov thiab yog qib stainless hlau ua raws li American ASTM tus qauv, uas yog sib npaug rau Tuam Tshoj tus 1Cr13 stainless hlau.Standard 401 stainless hlau belongs rau martensitic stainless hlau, uas muaj siab toughness thiab hardness.Nws tuaj yeem ua kom muaj kev ruaj ntseg qub txawm tias qhov kub thiab txias, thiab nws tsis muaj tshuaj lom thiab tsis qab.
Nws muaj kev nyab xeeb heev los siv 401 stainless hlau ua tableware.Nws tsis yooj yim rau oxidize thiab poob tawm.Nws yog ruaj thiab poob-resistant.Tsis muaj teeb meem nrog cua sov nrog hluav taws kub thiab induction cooker, thiab nws yooj yim heev los ntxuav.
Nws yuav tsum tau muab sau tseg tias nws yog qhov zoo tshaj plaws tsis txhob siv 410 stainless hlau tableware los tuav cov zaub mov xws li ntsev thiab zaub kua zaub rau lub sij hawm ntev, txwv tsis pub, nws yuav ua rau cov tshuaj tiv thaiv kom yaj cov tshuaj lom hlau.
Cov yam ntxwv ntawm stainless hlau
Lub sij hawm "stainless steel" tsis yog tsuas yog xa mus rau ib hom stainless hlau, tab sis rau ntau tshaj ib puas industrial stainless hlau, txhua tus tsim los ua tau zoo nyob rau hauv nws daim ntawv thov tshwj xeeb.Tus yuam sij rau kev vam meej yog ua ntej nkag siab txog daim ntawv thov thiab tom qab ntawd txiav txim siab qib steel raug.Muaj feem ntau tsuas yog rau qib steel uas cuam tshuam nrog kev siv lub tsev.Lawv txhua tus muaj 17-22% chromium, thiab cov qib zoo dua kuj muaj npib tsib xee.Qhov sib ntxiv ntawm molybdenum tuaj yeem txhim kho atmospheric corrosion, tshwj xeeb tshaj yog corrosion kuj rau chloride-muaj cua.
piv rau carbon steel
1. Ceev ceev
Qhov ntom ntawm carbon steel yog me ntsis siab dua li ntawm ferritic thiab martensitic stainless hlau, thiab me ntsis qis dua li ntawm austenitic stainless hlau;
2. Kev tiv thaiv
Lub resistivity nce nyob rau hauv qhov kev txiav txim ntawm carbon steel, ferritic, martensitic, thiab austenitic stainless hlau;
3. Qhov kev txiav txim ntawm linear expansion coefficient zoo sib xws, austenitic stainless hlau yog qhov siab tshaj plaws, thiab carbon hlau yog qhov tsawg tshaj plaws;
4. Carbon steel, ferritic thiab martensitic stainless hlau yog sib nqus, thiab austenitic stainless hlau tsis yog hlau nplaum, tab sis lawv cov kev ua haujlwm txias yuav ua kom muaj hlau nplaum thaum lawv tsim martensitic transformation, thiab kev kho cua sov tuaj yeem siv los tshem tawm cov martensite no.cov ntaub so ntswg thiab kho nws cov khoom tsis sib nqus.
Piv nrog carbon steel, austenitic stainless hlau muaj cov yam ntxwv hauv qab no:
1) High resistivity, li ntawm 5 npaug ntawm carbon steel.
2) Loj linear expansion coefficient, 40% loj dua carbon steel, thiab nrog rau qhov kub thiab txias, tus nqi ntawm linear expansion coefficient kuj nce raws li.
3) Tsawg thermal conductivity, txog 1/3 ntawm carbon steel.
