Low Carbon Steel vs High Carbon Steel
Qhov sib txawv ntawm cov pa roj carbon tsawg thiab cov pa roj carbon siab, raws li lub npe qhia, stems los ntawm cov pa roj carbon ntau hauv cov hlau. Feem ntau, hlau yog hu ua 'Carbon Steel' qhov twg lub ntsiab alloying tivthaiv siv yog Carbon thiab thaum tsis muaj lwm yam ntsiab lus yuav tsum tau teev xws li Chromium, Cob alt, Nickel. Ib yam li cov lus txhais tau hais tseg, High carbon steel muaj cov pa roj carbon ntau dua thiab hauv cov pa roj carbon tsawg muaj tsawg feem pua ntawm carbon.
High Carbon Steel yog dab tsi?
Feem ntau, cov pa roj carbon siab muaj txog 0.30-1.70% carbon los ntawm qhov hnyav. Kev nce cov pa roj carbon feem pua hauv cov hlau ua rau nws muaj zog ntxiv thiab nws tseem suav tias yog qhov kev lag luam tshaj plaws los ua kom lub zog ntawm cov hlau. Txawm li cas los xij, vim tias ntxiv cov pa roj carbon ntau, cov hlau kuj tseem ua rau nkig thiab tsis tshua muaj zog. Yog li ntawd, txoj cai sib npaug ntawm cov pa roj carbon yuav tsum tau ntxiv txhawm rau txhawm rau ua tiav cov hlau ua haujlwm ntxiv.
Cov pa roj carbon ntau tuaj yeem kho cua sov zoo dua li cov pa roj carbon tsawg thiab yog li muaj txiaj ntsig zoo hauv ntau daim ntawv thov. Lwm yam impurities tseem tuaj yeem nqa cov khoom nthuav dav rau hlau; Piv txwv li, Sulphur. Qee qhov kev siv ntawm cov pa roj carbon siab muaj xws li cov rail steels, pre-stressed qhob, hlau hlua, lub log tsheb, riam, saw hniav, iav log, chains, thiab lwm yam.
Cov kev siv ntau yam ntawm cov pa roj carbon siab muaj xws li cov cuab yeej txiav
Yuav ua li cas carbon tsawg?
Qhov no yog hom hlau siv ntau tshaj plaws niaj hnub no vim yog tus nqi tsim khoom tsawg. Nws feem ntau muaj cov pa roj carbon ntau ntawm 0.05 - 0.15% los ntawm qhov hnyav. Cov pa roj carbon tsawg feem ntau softer thiab tsis muaj zog dua li lwm hom hlau, tab sis nws muaj peev xwm muab cov khoom siv ntawm cov qauv siv tau rau ntau yam kev lag luam thiab kev siv niaj hnub.
Qhov zoo ntawm nws ua softer thiab tsis muaj zog ua rau nws yooj yim rau vuam thiab tuaj yeem hloov mus rau hauv cov duab sib txawv ua rau muaj ntau yam khoom sib txawv. Nws feem ntau yog ua rau hauv cov ntawv tiaj tus dov los yog strips ntawm cov hlau. Raws li qhov tshwm sim ntawm nws qhov kev ua tau zoo, cov pa roj carbon tsawg tuaj yeem muab dov rau hauv lub cev lub cev. Thaum cov pa roj carbon tsawg yog siv los ua cov vaj huam sib luag, cov ntsiab lus ntawm cov pa roj carbon monoxide nyob rau hauv cov hlau tsis tshua muaj nyob ib ncig ntawm 0.05%. Tab sis cov ntsiab lus carbon ntau dua nyob ib ncig ntawm 0.15% yog yuav tsum tau thaum tsim steel qauv daim hlau, forgings, thiab lwm yam. Tsawg carbon steel yog siv los ua ntau yam khoom. Cov khoom siv hauv tsev, cov khoom siv hauv lub cev, cov hlau tsis tshua muaj carbon steel, thiab cov phaj tin yog qee qhov kev siv ntau tshaj plaws.
Carbon steel hlau - ib qho kev siv ntawm cov pa roj carbon tsawg
Qhov txawv ntawm Low Carbon Steel thiab High Carbon Steel yog dab tsi?
Cov ntsiab lus Carbon:
• High carbon steel muaj cov pa roj carbon feem pua ntawm 0.30 - 1.70% los ntawm qhov hnyav.
• Cov pa roj carbon tsawg muaj cov ntsiab lus carbon ntawm 0.05 - 0.15% los ntawm qhov hnyav.
Zoo:
• High carbon steel muaj zog dua li cov pa roj carbon tsawg.
Brittleness:
• Cov pa roj carbon siab yog nkig thiab tuaj yeem tawg yooj yim thaum piv rau cov hlau tsis tshua muaj.
vuam:
• Cov pa roj carbon siab yog ntxhib ua rau nws nyuaj rau vuam rau hauv cov duab sib txawv.
• Vim lub zog softer thiab tsis muaj zog ntawm cov pa roj carbon tsawg nws tuaj yeem yooj yim welded rau hauv cov duab sib txawv.
Kev Kho Mob Kub:
• Cov pa roj carbon ntau tuaj yeem ua tiav kev kho cua sov dua li cov pa roj carbon tsawg.
Kev siv cov pa roj carbon tsawg thiab cov pa roj carbon siab:
• Qee yam kev siv cov pa roj carbon ntau yog cov hlau rail, cov pob zeb ua ntej kev nyuaj siab, hlua hlua, lub log tsheb, riam, saw hniav, iav log, thiab chains.
• Qee cov kev siv cov pa roj carbon tsawg yog cov tsheb hauv lub cev, cov hlau tsis tshua muaj carbon steel, thiab cov hlau tin.
Price:
• High carbon steel yog kim dua.
• Tsawg carbon steel yog pheej yig dua.
