Dab tsi yog 4 hom carbon steel?
Cov pa roj carbon steel yog ib qho ntawm cov khoom siv dav siv hauv ntiaj teb vim nws pheej yig, ua haujlwm ntev, thiab ntau yam. Hom hlau no yog tsim los ntawm kev sib xyaw hlau thiab carbon, nrog rau lwm cov khoom ntxiv los txhim kho nws cov khoom. Cov pa roj carbon steel paub txog nws lub zog siab, hardness, thiab tsis kam hnav, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau ntau yam kev siv.
Muaj plaub yam tseem ceeb ntawm cov pa roj carbon steel: cov pa roj carbon tsawg, cov pa roj carbon nruab nrab, cov pa roj carbon siab, thiab cov pa roj carbon ntau. Txhua hom muaj nws cov khoom tshwj xeeb thiab kev siv, thiab kev nkag siab lawv yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog lossis siv cov pa roj carbon steel.
Tsawg Carbon Steel
Cov pa roj carbon tsawg yog feem ntau siv cov pa roj carbon steel, thiab nws muaj nyob nruab nrab ntawm {{0}}.05% thiab 0.30% carbon. Hom carbon steel no tseem hu ua me me hlau lossis cov pa roj carbon steel. Tsawg carbon steel yog ib qho yooj yim mus ua hauj lwm nrog thiab yog tus pheej yig, ua rau nws yog ib tug zoo tagnrho cov ntaub ntawv rau ntau yam kev siv.
Cov pa roj carbon tsawg yog siv rau hauv kev tsim kho, kev tsim tsheb, tshuab, thiab lwm yam lag luam. Nws kuj yog siv dav hauv kev tsim cov bolts, ceev, thiab cov ntsia hlau, nrog rau kev tsim cov khoom siv xws li kab teeb thiab kab.
Txawm hais tias nws muaj ntau qhov zoo, cov pa roj carbon tsawg muaj qee qhov kev txwv. Nws tsis muaj zog npaum li lwm hom carbon steel thiab muaj qis hnav tsis kam. Tsis tas li ntawd, cov hlau tsis muaj cov pa roj carbon monoxide tsis muaj cua sov zoo li lwm hom thiab tuaj yeem ua rau tawg lossis tawg thaum raug kub.
Nruab nrab Carbon Steel
Cov pa roj carbon nruab nrab yog ib hom carbon steel uas muaj nyob nruab nrab ntawm {{0}}.30% thiab 0.60% carbon. Hom hlau no muaj zog dua li cov hlau tsis muaj carbon tsawg thiab muaj kev hnav zoo dua. Cov pa roj carbon nruab nrab feem ntau yog siv rau hauv kev tsim cov iav, axles, thiab shafts.
Cov pa roj carbon nruab nrab kuj tseem siv rau hauv kev tsim cov khoom siv tsheb, xws li cov springs thiab ncua kev kawm ntawv. Nws yog lub npe hu rau nws qhov zoo sib npaug ntawm lub zog thiab ductility, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov ntawv thov uas xav tau ob qho tib si.
High Carbon Steel
Cov pa roj carbon ntau yog ib hom carbon hlau uas muaj nyob nruab nrab ntawm 0.60% thiab 1.00% carbon. Hom hlau no paub txog nws lub zog siab thiab hardness, nrog rau nws hnav tsis kam. High carbon steel yog siv rau hauv kev tsim cov riam, txiav cov cuab yeej, thiab lwm yam khoom ntse.
High carbon steel kuj yog siv rau hauv kev tsim cov springs thiab lwm yam khoom uas yuav tsum tau muaj zog thiab durability. Nws yog lub npe hu rau nws lub peev xwm los tuav ib tug ntse ntug thiab tiv thaiv dabtsi yog khoov thiab tawg.
Txawm hais tias nws muaj ntau qhov zoo, cov pa roj carbon ntau muaj qee qhov kev txwv. Nws yog nkig thiab tuaj yeem ua haujlwm nyuaj, ua rau nws tsis haum rau qee qhov kev siv. Tsis tas li ntawd, nws tuaj yeem ua rau xeb thiab xeb yog tias tsis tswj xyuas kom zoo.
High Carbon Steel
Cov pa roj carbon ntau heev yog hom carbon hlau uas muaj nyob nruab nrab ntawm 1.00% thiab 2.00% carbon. Hom hlau no tsis tshua muaj zog thiab tawv, tab sis nws kuj yog nkig heev. Cov pa roj carbon ntau heev yog siv rau hauv kev tsim cov cuab yeej txiav, riam, thiab lwm yam khoom ntse.
Txawm hais tias nws lub zog, cov pa roj carbon ntau heev tsis haum rau txhua daim ntawv thov. Nws brittleness ua rau nws yooj yim dua rau kev tawg thiab tawg, tshwj xeeb tshaj yog nyob rau hauv kev ntxhov siab lossis cuam tshuam. Tsis tas li ntawd, carbon hlau siab heev tuaj yeem ua haujlwm nyuaj, ua rau nws tsis haum rau qee qhov kev tsim khoom.
Xaus
Cov pa roj carbon steel yog cov khoom siv ntau yam thiab siv dav hauv ntau yam kev lag luam. Kev nkag siab txog ntau hom carbon steel yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog lossis siv cov khoom siv no. Cov pa roj carbon tsawg yog qhov zoo tagnrho rau ntau yam kev siv, thaum nruab nrab carbon steel muaj qhov sib npaug ntawm lub zog thiab ductility. Cov pa roj carbon ntau yog lub npe hu rau nws lub zog siab thiab hardness, thaum cov pa roj carbon ntau yog tsis tshua muaj zog thiab tawv, tab sis kuj nkig heev. Los ntawm kev nkag siab txog cov khoom thiab kev siv ntawm txhua hom carbon steel, koj tuaj yeem xaiv cov khoom tsim nyog rau koj daim ntawv thov tshwj xeeb.
