Cov tsos mob: Cov tsos ntawm stainless hlau yog ci nyiaj, thaum xim ntawm cov hlau yog grey thiab tsaus.
Corrosion tsis kam: Carbon steel yog yooj yim oxidized thiab xeb thaum raug rau ib puag ncig. Stainless hlau muaj chromium ntxiv yog li nws muaj zog dua li cov hlau.
Hnav tsis kam: Carbon steel yog ib qho nyuaj tshaj li stainless hlau.
Nqe: Hauv kev tsim cov hlau tsis muaj steel, ntau cov khoom sib txuas ntxiv tau ntxiv, thaum cov hlau tsis muaj carbon steel, yog li tus nqi ntawm cov hlau tsis xeb yog kim dua cov hlau.
Ductility: Stainless hlau yog ductile ntau dua carbon steel vim nws cov ntsiab lus siab nickel.
1. Qhov txawv txav
Stainless hlau yog tsim los ntawm qee cov hlau xws li chromium thiab npib tsib xee, yog li cov tsos ntawm stainless hlau yog ci nyiaj, du nyob rau hauv tsos, thiab muaj gloss zoo heev. Cov pa roj carbon monoxide yog ib qho alloy ntawm carbon thiab hlau, yog li cov xim ntawm cov hlau yog grey, thiab qhov saum npoo yog rougher dua stainless hlau.
2. Txawv corrosion kuj
Cov pa roj carbon steel thiab stainless hlau muaj hlau, thiab peb txhua tus paub tias hlau nws tus kheej yuav maj mam oxidize thaum raug rau ib puag ncig, ua rau saum npoo xeb. Tab sis stainless hlau yog ntxiv nrog chromium, uas yog feem ntau ua ke nrog oxygen 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 cov chromium me me tsis tuaj yeem tsim cov chromium oxide txheej, yog li cov corrosion kuj ntawm stainless hlau yuav zoo dua li cov carbon hlau.
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 tsis muaj zog. 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 npaum li cas 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 yog zoo dua li ntawm cov hlau, feem ntau vim hais tias cov nickel cov 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 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.
