316 stainless hlau thiab 304 stainless hlau flange lossis yeeb nkab

Hauv kev siv cov cuab yeej siv cov kav dej, ntau yam khoom yog ua los ntawm stainless hlau los yog koom nrogstainless hlau cov ntaub ntawv. Txawm hais tias lawv txhua tus yog cov hlau tsis muaj steel, muaj ntau hom stainless hlau, xws li 304 thiab 316 qauv. Cov qauv sib txawv muaj qhov sib txawv ntawm lub cev

Qhov sib txawv ntawm 316 stainless hlau thiab 304 stainless hlau

1. Tshuaj muaj pes tsawg leeg

304 stainless hlau: muaj 18% chromium thiab 8% npib tsib xee, nrog rau me me ntawm carbon, manganese, thiab silicon.

316L stainless hlau: muaj 16% chromium, 10% npib tsib xee, thiab 2% molybdenum, nrog rau me me ntawm carbon, manganese, thiab silicon.

2. Corrosion kuj

304 stainless hlau: Nws muaj kev tiv thaiv corrosion zoo, tshwj xeeb tshaj yog rau huab cua dav dav, dej, thiab tshuaj lom neeg nrog kev ruaj ntseg zoo, tab sis nws yooj yim rau pitting thiab intergranular corrosion hauv xov xwm uas muaj chloride ions.

316L stainless hlau: Nws muaj kev tiv thaiv corrosion zoo dua li 304 stainless hlau, tshwj xeeb tshaj yog rau cov xov xwm uas muaj chloride ions, acidic thiab alkaline ib puag ncig, nrog kev ruaj ntseg zoo.

3. Lub zog thiab hardness

304 stainless hlau: muaj zog zoo thiab hardness, tab sis me ntsis qis dua 316L stainless hlau.

316L stainless hlau: Piv rau 304 stainless hlau, nws muaj zog dua thiab hardness.

4. Kev ua haujlwm vuam

304 stainless hlau: Nws muaj qhov zoo weldability thiab tuaj yeem siv rau feem ntau txoj kev vuam, tab sis nws yooj yim rau intergranular corrosion nyob rau hauv qhov kub thiab txias.

316L stainless hlau: Piv rau 304 stainless hlau, nws yog ib qho nyuaj rau vuam, tab sis nws muaj kev vuam zoo nyob rau hauv qhov kub thiab txias thiab tsis tshua muaj kev cuam tshuam intergranular corrosion.

5. Nqe sib txawv

Piv nrog rau cov pa roj carbon steel, stainless hlau yog kim dua, thaum nyob rau hauv stainless hlau, 316 stainless hlau kim dua, feem ntau yog vim cov nqi ntau lawm thiab kev pab lub neej ntev, yog li tus nqi yuav kim dua.

6. Scope ntawm kev siv

Stainless hlau 316 muaj ntau yam kev siv ntau dua piv rau stainless hlau 304. Piv txwv li, stainless hlau 316 khoom siv tau rau hauv kev lag luam khoom noj, nrog rau cov khoom siv kho mob, thiab tuaj yeem ua lub luag haujlwm tseem ceeb.

Daim ntawv thov ntau yam ntawm 304 stainless hlau

Stainless hlau 304, raws li ib hom hlau, yog dav siv nyob rau hauv ntau yam vim nws kub tsis kam thiab corrosion kuj. Yog li nyob rau hauv qee qhov chaw ntub dej, xaiv 304 stainless hlau tuaj yeem ua kom lub sijhawm ntev xeb, vim nws tuaj yeem siv los ua cov kav hlau uas muaj zog corrosion kuj. Qhov no kuj yog vim li cas vim li cas ntau cov yeeb nkab steel hlau 304 raug xaiv rau kev thauj mus los hauv cov kav dej.

Ntawm peb lub tuam txhab cov khoom, feem ntau yog covstainless hlau flanges, stainless hlau yeeb nkab fittings, thiabstainless hlau kav.
