Raws li peb txhua tus paub, muaj ntau hom hlau nyob rau hauv kev ua lag luam tam sim no, xws li carbon steel thiab stainless hlau, uas muaj ntau rau peb, thiab lawv cov duab kuj zoo sib xws, uas ua rau ntau tus neeg tsis tuaj yeem paub qhov txawv.
Dab tsi yog qhov txawv ntawm carbon steel thiab stainless hlau?
1. Qhov txawv txav
Stainless hlau yog tsim los ntawm chromium, npib tsib xee thiab lwm yam hlau, yog li cov tsos ntawm stainless hlau yog silvery, du thiab zoo heev gloss. Cov pa roj carbon steel yog tsim los ntawm cov pa roj carbon thiab hlau alloy, yog li cov xim ntawm cov hlau yog grey, thiab qhov saum npoo yog ntxhib dua li cov hlau tsis muaj steel.
2. Txawv corrosion kuj
Ob leeg carbon steel thiab stainless hlau muaj hlau. Peb txhua tus paub tias hlau yuav maj mam oxidize thaum raug rau ib puag ncig, uas ua rau nto xeb. Tab sis yog tias chromium ntxiv rau stainless hlau, nws yuav ua ke nrog oxygen ntau dua hlau. Tsuav yog chromium nyob rau hauv oxygen, nws yuav tsim ib txheej chromium oxide, uas tuaj yeem tiv thaiv cov hlau ncaj qha los ntawm kev degradation thiab corrosion. Cov ntsiab lus chromium ntawm carbon steel kuj yuav qis dua, yog li ib qho me me ntawm chromium tsis tuaj yeem tsim chromium oxide txheej, yog li qhov corrosion kuj ntawm stainless hlau yuav zoo dua li cov pa roj carbon steel.
3. Txawv hnav tsis kam
Cov pa roj carbon steel yuav nyuaj dua li cov hlau tsis muaj steel, tab sis nws yuav hnyav dua thiab tsawg dua yas. Yog li ntawd, nyob rau hauv cov nqe lus ntawm hnav tsis kam, nws cov pa roj carbon steel yog ntau hnav-resistant dua stainless hlau.
4. Cov nqi sib txawv
Nyob rau hauv tus txheej txheem ntawm kev ua stainless hlau, ib tug tej yam nyiaj ntawm lwm yam alloys yuav tsum tau ntxiv, tab sis carbon steel yog kiag li txawv los ntawm kev ntxiv ib tug loj tus naj npawb ntawm lwm yam alloys, yog li tus nqi ntawm stainless hlau yog kim kim tshaj carbon hlau.
5. Txawv ductility
Lub ductility ntawm stainless hlau yuav zoo dua li cov pa roj carbon steel, feem ntau vim hais tias cov nickel ntsiab lus nyob rau hauv stainless hlau yog kuj siab, thiab ductility ntawm cov ntsiab lus tseem zoo dua, yog li cov ductility ntawm stainless hlau kuj yuav zoo dua. Cov pa roj carbon steel muaj tsawg dua nickel, uas tuaj yeem tsis quav ntsej ncaj qha, tab sis muaj qhov tsis zoo.
Qhov zoo thiab qhov tsis zoo ntawm stainless hlau thiab carbon hlau.
1. Nyob rau hauv cov nqe lus ntawm hardness, carbon hlau yog ib qho nyuaj tshaj stainless hlau. Nyob rau hauv cov nqe lus ntawm kev siv, stainless hlau yuav ntau ruaj.
2. Stainless hlau yog dav siv hauv tsev neeg lub neej. Nws tuaj yeem siv ua chav ua noj countertop, txee qhov rooj, thiab lwm yam. Tab sis nws tsis haum rau cov khoom noj. Stainless hlau yuav tsim tshuaj lom thaum rhuab.
3. Tus nqi ntawm cov pa roj carbon steel yog qis dua cov hlau tsis muaj steel, thiab nws kuj yooj yim dua rau kev tsim khoom, tab sis nws qhov tsis zoo yog cov hlau tsis zoo yuav ua rau qhov kub thiab txias, thiab nws yooj yim poob nws lub zog sib nqus nyob rau hauv magnetic induction.
