Yuav ua li cas paub qhov txawv ntawm 304 stainless hlau thiab 201 stainless hlau?
Cov txheej txheem kom paub qhov txawv 304 stainless hlau thiab 201 stainless hlau: 1. Qhov sib txawv ntawm cov roj qaug zog: 201 stainless hlau muaj lub zog ntau dua, tab sis nws cov tawv tawv tsis zoo li 304 stainless hlau, yog li 304 stainless hlau muaj lub zog ntau dua me ntsis. 2. Qhov sib txawv hauv qhov zoo: Zuag qhia tag nrho cov khoom zoo ntawm 304 stainless hlau phaj zoo dua, thiab tus nqi kuj nce siab dua li ntawm 201 stainless hlau phaj, thiab qhov zoo ntawm 201 yog me ntsis zuj zus. 304 stainless hlau phaj yog ua los ntawm txawv teb steel, thaum 201 yog ua los ntawm cov hlau tsis muaj steel. 3. Qhov sib txawv ntawm cov hlau tsim: Cov ntsiab lus tseem ceeb ntawm 201 stainless hlau phaj yog 17Cr-4.5Ni-6Mn-N, uas yog hom Ni zoo li hlau, uas yog lwm txoj hauv 301 steel. Tom qab qee lub sijhawm ua haujlwm txias, cov hlau nplaum yuav tau thiab siv nyob rau hauv cov tsheb ciav hlau. 304 stainless hlau phaj tau txheej txheem rau 18Cr-9Ni, uas yog cov feem ntau siv cov hlau stainless phaj thiab kub-resistant steel phaj hauv khw. Feem ntau siv rau hauv cov khoom siv ua khoom noj, ntau yam khoom siv tshuaj lom neeg, kev tsim hluav taws xob nuclear thiab kev lag luam nuclear lub zog, thiab lwm yam 4. Qhov sib txawv ntawm manganese thiab nickel element cov ntsiab lus: 201 stainless hlau phaj muaj ntau dua manganese keeb, thiab saum npoo ntawm steel phaj yog ci thiab muaj lub teeb npub, tab sis nws yooj yim dua xeb yog tias cov ntsiab lus manganese muaj ntau. Txawm li cas los xij, cov ntsiab lus chromium ntawm 304 stainless hlau phaj yog qhov siab, thiab saum npoo ntawm cov hlau dav dav yuav tshwm matt, thiab nws tsis yooj yim rau xeb. Qhov tseem ceeb tshaj plaws ntawm ob daim hlau hlau yog qhov sib txawv hauv kev ua hauj corrosion. Kev xeb ntawm kev txhuam tag nrho ntawm 201 yog qhov tsawg, nws yooj yim yuav xeb, thiab tus nqi yuav pheej yig dua. Ntxiv mus, cov ntsiab lus nickel ntawm 201 yog qhov tsawg, thiab tus nqi qis dua li ntawm 304 stainless hlau. Qhov loj tshaj qhov sib txawv ntawm 201 stainless hlau phaj thiab 304 stainless hlau phaj yog cov teeb meem ntawm nickel. Txawm li cas los xij, tus nqi ntawm 304 yog me ntsis kim dua, thiab 304 stainless hlau phaj tau tsawg kawg yog khaws cia nyob rau hauv ib qho kev siv yam tsis muaj xeb.
