Ntawm cov ntaub ntawv stainless hlau, 304 stainless hlau thiab 201 stainless hlau yog ob hom. Lawv muaj qee qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, lub cev muaj zog, thiab kev siv.

Ua ntej ntawm tag nrho cov, 304 stainless hlau yog stainless hlau nrog siab corrosion kuj, muaj 18% chromium thiab 8% npib tsib xee, nrog rau ib feem me me ntawm cov ntsiab lus xws li carbon, silicon, thiab manganese. Cov tshuaj muaj pes tsawg leeg no muab 304 stainless hlau zoo corrosion kuj, oxidation tsis kam, thiab kub-resistant. Nws kuj muaj lub zog siab thiab ductility, yog li nws feem ntau siv rau hauv kev tsim cov khoom siv thiab cov khoom siv nrog cov kev xav tau siab dua.

201 stainless hlau yog tsim los ntawm 17% mus rau 19% chromium thiab 4% mus rau 6% npib tsib xee, nrog rau me me ntawm carbon, manganese, thiab nitrogen. Piv nrog rau 304 stainless hlau, 201 stainless hlau muaj qis nickel cov ntsiab lus, yog li nws cov corrosion kuj thiab high-temperature kuj tsis zoo. Txawm li cas los xij, 201 stainless hlau muaj lub zog zoo dua thiab cov yas zoo dua thiab tsim nyog rau qee qhov kev thov qis qis thiab cov ntawv thov zoo nkauj.

Hais txog lub cev lub cev, qhov ntom ntawm 304 stainless hlau loj dua, txog 7.93 grams / cubic centimeter, thaum qhov ceev ntawm 201 stainless hlau yog li 7.86 grams / cubic centimeter. Tsis tas li ntawd, 304 stainless hlau muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv thaiv corrosion los ntawm huab cua, dej tshiab, chav, thiab tshuaj lom neeg; thaum 201 stainless hlau yuav ua rau corrosion nyob rau hauv ib co corrosive ib puag ncig.

Nyob rau hauv cov nqe lus ntawm daim ntawv thov, 304 stainless hlau feem ntau yog siv nyob rau hauv kev tsim cov khoom siv tshuaj, quab yuam cov hlab ntsha, khoom noj khoom haus, thiab lwm yam teb uas yuav tsum tau muaj corrosion kuj thiab high-temperature kuj. 201 stainless hlau feem ntau yog siv rau hauv kev tsim cov khoom siv hauv chav ua noj, kho kom zoo nkauj hauv tsev, thiab lwm yam uas yuav tsum tau muaj zog thiab yas tab sis kuj tsis tshua muaj corrosion.

Feem ntau, 304 stainless hlau muaj zoo corrosion kuj, kub-resistant, thiab oxidation tsis kam tshaj 201 stainless hlau, thiab yog haum rau industrial teb nrog ntau dua cov kev xav tau. 201 stainless hlau yog qhov tsim nyog rau cov ntawv thov uas muaj zog dua thiab cov kev xav tau ntawm plasticity tab sis kuj tsis tshua muaj corrosion kuj. Thaum xaiv cov khoom siv stainless hlau, kev xaiv yuav tsum yog raws li kev siv tshwj xeeb thiab cov kev xav tau.
