Hais txog qhov zoo ntawm 304 stainless hlau yeeb nkab

304 stainless hlau cov khoom yog cov khoom siv kev noj qab haus huv tau lees paub uas tuaj yeem cog rau hauv tib neeg lub cev, thiab siv yuav luag txhua qhov chaw cuam tshuam txog tib neeg kev noj qab haus huv. Nws tau siv dav. Stainless hlau dej yeeb nkab yog cov khoom siv zoo ib puag ncig, ua tau raws li kev noj qab haus huv, tuaj yeem siv tau 100 feem pua, txuag dej, txo nqi tsheb thauj mus los, txo cov cua sov, tsis txhob muaj kuab paug thiab lwm yam zoo. Cov lus qhia ntxaws ntxaws yog raws li hauv qab no:

1. Lub neej

304 stainless hlau yeeb nkab muaj lub neej ua haujlwm ntev tshaj plaws. Los ntawm kev txheeb xyuas ntawm kev siv cov hlau tsis muaj steel nyob txawv teb chaws, kev pabcuam lub neej ntawm cov kav dej stainless hlau tuaj yeem ncav cuag 100 xyoo, tsawg kawg yog 70 xyoo, ntev npaum li lub neej ntawm cov tsev.

2. Lub zog

Lub zog tensile ntawm 304 stainless hlau yeeb nkab yog 2 npaug ntawm cov yeeb nkab steel, thiab 8 mus rau 10 npaug ntawm cov yeeb nkab yas. Lub zog ntawm cov khoom txiav txim siab seb cov yeeb nkab dej puas muaj zog thiab kev sib tsoo-resistant, muaj kev nyab xeeb thiab txhim khu kev qha. Kev nyab xeeb thiab kev ntseeg siab yog qhov tseem ceeb tshaj plaws rau kev tsim cov khoom siv dej. Nyob rau hauv cov ntaub ntawv ntawm kev cuam tshuam sab nraud, qhov muaj peev xwm ntawm cov xau ntawm cov kav dej stainless hlau yog qhov tsawg heev. Kev ua haujlwm siab ntawm cov khoom siv dej hauv cov tsev siab siab feem ntau ntau dua 0.6Mpa; Kev kub siab xav tau rau cov kav dej. Nyias-walled stainless hlau yeeb nkab vim muaj cov khoom siv zoo heev, tuaj yeem tiv taus cov dej siab siab, mus txog 10Mpa lossis ntau dua, tshwj xeeb tshaj yog tsim rau cov dej siab siab.

3. Corrosion kuj

Ib qho ntawm qhov zoo tshaj plaws ntawm 304 stainless hlau yeeb nkab yog nws cov corrosion kuj zoo heev, uas yog qhov zoo tshaj plaws hauv ntau cov kav dej. Vim tias cov hlau tsis muaj hlau tsis muaj zog tuaj yeem cuam tshuam nrog oxidizers, tawv thiab ntom chromium-nplua nuj oxide tiv thaiv zaj duab xis Dr2O3 yog tsim rau ntawm qhov chaw, uas zoo tiv thaiv cov tshuaj tiv thaiv oxidation ntxiv. Lub peev xwm passivation ntawm lwm cov kav hlau hlau, xws li cov kav dej galvanized thiab cov kav dej tooj liab yog qhov tsawg heev, uas yog qhov laj thawj tseem ceeb vim li cas qhov corrosion kuj ntawm cov kav dej tooj liab ntawm cov kav dej galvanized yog tsawg dua li cov kav hlau stainless. Stainless hlau tsis muaj corrosion zoo li carbon steel, thiab tsis muaj kev tiv thaiv txheej thaum siv; Kev siv cov kav dej stainless hlau, tsis muaj kev txwv rau cov tshuaj muaj pes tsawg leeg ntawm cov dej, vim tias cov hlau tsis muaj corrosion kuj zoo nyob rau hauv ntau cov ntsiab lus oxygen, kub, PH thiab hardness ntawm dej; Cov kav dej stainless hlau tuaj yeem tiv taus tus nqi siab heev, txawm tias tus nqi ntws ntau dua 40 m / s, tseem tuav tus nqi qis heev, tsis ntau tshaj 0.003 hli / xyoo, tshwj xeeb tshaj yog tsim rau cov khoom siv dej siab. Stainless hlau feem ntau tsis tshwm sim hauv zos corrosion, 304 stainless hlau tuaj yeem tiv taus cov ntsiab lus chloride txog li 200ppm, 316 stainless hlau tuaj yeem tiv taus cov ntsiab lus chloride txog li 1000ppm, qhov kev txiav txim siab no yog raws li cov ntaub ntawv kuaj pom thiab tau lees paub los ntawm kev paub dhau los. Cov coefficient ntawm thermal expansion ntawm stainless hlau yeeb nkab yog hais txog tib yam li ntawm cov yeeb nkab tooj liab, uas yog 1.5 npaug ntawm cov yeeb nkab zoo tib yam, piv nrog cov yeeb nkab steel hlau, uas muaj cov yam ntxwv ntawm qeeb thermal expansion thiab txias contraction.

4. Thaum tshav kub kub thiab rwb thaiv tsev

Lub thermal conductivity ntawm 304 stainless hlau yeeb nkab yog 1/25 ntawm cov yeeb nkab tooj liab thiab 1/4 ntawm cov yeeb nkab steel, uas yog tshwj xeeb tshaj yog tsim rau kev thauj mus los ntawm cov dej kub. Feem ntau siv stainless hlau hauv kev lag luam dej yog 316 thiab 304 stainless hlau, uas tuaj yeem ua tau raws li feem ntau ntawm kev kho dej thiab kev thauj mus los.
