Dab tsi yog 3 hom stainless hlau?
Oct 17, 2023
Stainless hlau yog ib hom hlau nrov uas feem ntau siv rau hauv ntau daim ntawv thov vim nws zoo heev corrosion kuj, durability, thiab versatility. Nws muaj chromium, uas muab nws cov khoom tshwj xeeb, thiab ntau hom stainless hlau tuaj yeem muaj ntau qhov sib txawv ntawm lwm cov alloying ntsiab los txhim kho nws cov kev ua tau zoo. Ntawm no yog peb yam tseem ceeb ntawm stainless hlau:
1. Austenitic stainless hlau: Hom stainless hlau no feem ntau siv rau hauv kev lag luam thiab hauv tsev. Nws muaj cov qib siab ntawm chromium thiab npib tsib xee, uas muab nws zoo heev corrosion kuj thiab ci thiab ci zoo li. Nws kuj yog ductile thiab yooj yim rau kev ua haujlwm nrog, ua rau nws nrov rau cov khoom siv hauv chav ua noj, cov kav dej, thiab lwm yam khoom zoo nkauj.
2. Ferritic stainless hlau: Cov hlau tsis muaj steel hlau no zoo heev rau corrosion thiab oxidation, ua rau nws zoo tagnrho rau siv nyob rau hauv ib puag ncig hnyav. Nws muaj cov qib siab ntawm chromium thiab muaj cov ntsiab lus nickel qis dua li austenitic stainless hlau, muab nws tus nqi qis dua thiab cov khoom sib txawv me ntsis. Nws yog feem ntau siv rau hauv cov khoom siv tsheb, cov tshuab tso pa, thiab cov khoom siv.
3. Martensitic stainless hlau: Hom stainless hlau no paub txog nws lub zog siab thiab hardness, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau ua kom ntev thiab hnav tsis kam. Nws muaj cov pa roj carbon ntau thiab qis dua ntawm chromium thiab npib tsib xee, muab nws cov khoom tshwj xeeb uas ua rau nws nrov rau kev siv riam, hniav, thiab lwm yam cuab yeej txiav.
Hauv kev xaus, txhua hom stainless hlau muaj nws cov khoom tshwj xeeb thiab qhov zoo, thiab xaiv qhov zoo yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov. Txawm li cas los xij, tag nrho cov hlau tsis muaj stainless yog qhov ruaj khov thiab tiv taus corrosion, ua rau nws muaj ntau yam khoom siv thiab muaj txiaj ntsig hauv ntau qhov kev lag luam.
