Cov pa roj carbon steel yog ib pab pawg hlau nrog cov pa roj carbon ua lub ntsiab alloying thiab ib qho me me ntawm lwm cov khoom siv tshuaj. Raws li cov ntsiab lus ntawm cov pa roj carbon monoxide, cov cam khwb cia carbon hlau tuaj yeem muab faib ua cov pa roj carbon tsawg, nruab nrab carbon cam khwb cia hlau thiab siab carbon cam khwb cia hlau. Cov ntsiab lus ntawm cov pa roj carbon tsawg tsawg yog tsawg dua 0.25%, thaum cov ntsiab lus carbon ntawm nruab nrab cam khwb cia carbon steel yog nruab nrab ntawm 0.25% thiab 0.60%, thiab cov ntsiab lus ntawm cov pa roj carbon siab yog ntawm 0.60% thiab 3.0%. Lub zog thiab hardness ntawm cam khwb cia carbon steel nce nrog nce cov ntsiab lus carbon.Cam khwb cia carbon steel muaj qhov zoo hauv qab no: cov nqi tsim khoom qis dua, muaj zog dua, zoo dua toughness thiab ntau dua plasticity. Cam khwb cia carbon steel tuaj yeem siv los tsim cov khoom uas dais hnyav, xws li steel dov zeb sawv thiab hydraulic xovxwm hauv cov tshuab hnyav. Nws kuj tseem tuaj yeem siv los tsim cov khoom uas raug rau lub zog loj thiab cuam tshuam, xws li lub log, txuas txuas, bolsters thiab sab thav duab ntawm cov tsheb ciav hlau.
