Dab tsi yog qhov sib txawv ntawm 430 vs 304 stainless hlau los xij?
SS 430 daim ntawv?
Stainless hlau 430 nplooj ntawv yog lub ferritic, cov roj carless cov ntsiab lus muaj txog li 16%, thiab kab ntawm cov phosphorous thiab leej faj. Nws cov khoom ua pov thawj zoo heev corrosion tsis zoo nyob rau hauv ntau ib puag ncig ib puag ncig, tshwj xeeb tshaj yog nitric acid. 430 Stainless hlau feem ntau yog siv nyob rau hauv ob peb daim ntawv thov, suav nrog cov khoom siv, cov khoom siv trim, thiab cov khoom siv hauv tsev rau cov tshuab moldler.
Tsis zoo li lwm cov qib Austenic, 430 tsis nyuaj thaum lub sijhawm ua haujlwm nyuaj. Hloov chaw, nws ua nkig ntawm qhov kub thiab txias hauv qab no khov. Thaum muab khi, 430 yog ducile tab sis nyuaj dua rau weld tshaj 301 lossis 304 stainless hlau. Vim tias qhov no, cov chaw tsim khoom pom zoo kom siv cov pas nrig muab tub yees hauv 430.
Dhau li yog cov hlau tsis zoo, 430 muaj lub zog zoo thiab muaj zog. Yog tias vuas qib 430, nws yog qhov tseem ceeb uas yuav tsum siv cov neeg txias txias thiab ua kom muaj kev txiav yog ntse. SS li 430 nplooj ntawv yog tus nqi qis dua siv hauv kev tsim kho, automotive, kho kom zoo nkauj txiav, thiab lwm yam kev siv sab hauv thiab sab nraum zoov thiab sab nraum zoov thiab sab nraum zoov.
Dab tsi yog 304 stainless hlau los xij?
Cov ntawv tiaj tus ntaub ntawv, hlau stainless 304 daim ntawv, muaj 18% chromium, 8% tsawg dua, thiab ntau me me ntawm nitrogen. Qhov no Austenitic Alloy muab siab tensile lub zog, tiv taus rau corrosion, thiab machinatability. Qhov tsawg kawg los lees lub zog ntawm 304 stainless hlau los xij yog 205mpa. Nws ua haujlwm zoo rau cov khoom noj ua zaub mov, vaj tse vaj tse vaj tse, thiab cov tais diav ua noj.
Versatile Stainless hlau uas yog pheej yig yog 304 stainless hlau ntawv. Nws yog qhov kev xaiv zoo heev rau ntau cov ntawv thov vim nws lub zog thiab tiv taus rau corrosion. Nws yog tus qauv kev xaiv rau kev lag luam lossis cov ntawv cia ua lag luam, khoom siv tshuaj, thiab lwm yam yuav tsum muaj lub siab muaj kuab thiab oxidation tsis kam ua haujlwm 304 stainless ntawv. Ib qho ntxiv, nws tiv taus ntau cov tshuaj corrosive.
Qhov sib txawv ntawm 430 thiab 304 stainless hlau los xij
Niaj hnub no muaj ntau tshaj tawm cov qib stainless hlau yog 304 thiab 430 SS cov nplooj ntawv. Txhua tus muaj cov txiaj ntsig zoo thiab muaj peev xwm. Qhov sib xyaw ua ke ntawm cov hlau yog qhov sib txawv ntawm ob nplooj ntawv no. Txawm hais tias nws yog qhov yooj yim los tsim, nws tsis tuaj yeem phim 304 lub corrosion tsis kam. Vim hais tias ntawm Nickel concentration, 430 cov khoom siv kim dua 304. Cov muaj pes tsawg dua 3030 suav nrog kev sib xyaw ua ke, hlau, phosphorus, Sulphor, thiab silicon. Nws muaj cov ntsiab lus chromium qis thiab npib tsib xee dua li 304 cov khoom siv.
Qhov sib ntxiv ntawm Molybdenum nce corrosion tsis kam thiab txhim kho lub zog ntawm kev nce siab kub. Ib yam li ntawd, qhov sib ntxiv ntawm titanium tiv thaiv intergranular corrosion. Ntaus 430 yog qhov ferritic stainless uas ua ke zoo machinability thiab corrosion tsis kam. SS 304 cov ntawv muaj feem ntau siv hauv cov khoom siv, thiab huv huv yog muaj nyob hauv machining dawb thiab ruaj khov. Piv rau 304 cov khoom siv, 430 yog pheej yig dua thiab muaj cov ntsiab lus txog tsib xee tsawg dua. Nws tseem yog cov khoom siv uas tsis yog xeb.
