Stainless hlau nqus plua plav yog feem ntau ua los ntawm 201, 202 thiab 304 stainless hlau, thiab feem ntau ob yog 304 thiab 201 hlau tsis huv. Txawm hais tias cov ntaub ntawv sib txawv, cov tshuab nqus hlau stainless uas ua los ntawm cov khoom siv ob qho tib yam, thiab cov neeg zoo li tsis tuaj yeem txheeb tau lawv. Txawm hais tias cov neeg hauv kev lag luam stainless hlau kuj tsis tuaj yeem paub qhov txawv 100% ntawm 304 thiab 201 stainless hlau.
Nws tuaj yeem txiav txim los ntawm cov ntsiab lus hauv qab no.
1. 304 stainless hlau muaj muaj zog corrosion tsis kam thiab tus nqi siab: qhov tseem ceeb sib txawv ntawm 201 thiab 304 stainless hlau yog tsuas yog manifested nyob rau hauv lub ntsiab sib txawv muaj nyob rau hauv ob. Cov tshuaj tiv thaiv corrosion thiab stamping kev ua tau zoo ntawm 304 stainless hlau tau zoo tshaj li ntawm 201, thiab 304 stainless hlau feem ntau siv rau hauv qhov chaw uas ib puag ncig ua tau nyuaj thiab xav tau muaj zog corrosion tsis kam. 201 yog siv rau ib puag ncig lossis cov cai ntawm cov khoom siv tsis xeb hlau tsis ntau. Qhov chaw siab.
2. Tus nqi ntawm 304 stainless hlau yog siab dua: hauv nqe lus, 304 kuj tseem ntau dua li tus nqi 201. Vim tias qhov zoo ntawm 304 zoo dua 201 stainless hlau, thiab 304 yog import steel hlau phaj, thiab 201 yog domestic steel hlau phaj, tus nqi ntawm 304 yog siab dua.
3. 304 stainless hlau muaj cov tawv zoo dua: 201 steel hlau nyuaj dua, nrog me ntsis rigidity, thiab yooj yim dua rau tawg. Lub 304 stainless hlau nqus plua plav muaj cov npib tsib xee, yog li nws tsis xeb, thiab 304 stainless hlau tawv ntau dua thiab muaj qhov ua tau zoo tshaj tawm qaug zog dua 201.
4. 201 steel hlau tsis yooj yim rau xeb: 201 stainless hlau muaj manganese siab, thiab saum npoo zoo heev nrog tsaus nti thiab ci, thiab manganese siab yooj yim rau xeb. Lub tshuab nqus tsev ua los ntawm 304 stainless hlau muaj ntau chromium, thiab saum npoo yog matte thiab tsis xeb. Thaum xaiv cov nplaim hluav taws xob tsis muaj steel hlau, nws pom tseeb tias ob lub khob tau muab tso ua ke thiab sib piv. (Koj muaj peev xwm sim nrog potions)
5. 304 stainless hlau nqus plua plav tsis yooj yim rau xeb vim tias chromium-nplua nuj oxide tsim nyob rau saum npoo ntawm lub cev hlau tuaj yeem tiv thaiv cov hlau lub cev, kom ua tiav cov nyhuv ntawm kev haus dej haus huv. Cov hlau stainless 201 yog lub siab manganese stainless hlau, uas nws yog ib qho nyuaj tshaj li 304, cov pa roj carbon siab thiab nickel tsawg.
