Dab tsi yog low-carbon steel

Hais txog cov pa roj carbon tsawg, ntau tus neeg ua haujlwm yuav tsis muaj kev nkag siab zoo txog nws. Nws daim ntawv thov yog qhov dav heev, tshwj xeeb tshaj yog nyob rau hauv qee qhov kev tsim kho thiab kho kom zoo nkauj uas nws nquag siv. Txawm li cas los xij, yog tias koj xav siv nws cov txiaj ntsig tshwj xeeb zoo dua, koj yuav tsum xub nkag siab zoo txog cov pa roj carbon tsawg. Hauv qab no, tus editor yuav piav qhia meej tias cov hlau tsis tshua muaj carbon yog dab tsi, nws qhov zoo, qhov tsis zoo, thiab hom.

1. Tsawg carbon steel feem ntau muaj cov ntsiab lus carbon ntawm 0.10% rau 0.30%. Cov pa roj carbon tsawg kuj tuaj yeem ua tau yooj yim hauv ntau txoj hauv kev xws li forging, vuam, thiab txiav, feem ntau siv rau kev tsim cov chains, rivets, bolts, shafts, thiab lwm yam. Cov pa roj carbon steel nrog cov ntsiab lus carbon feem ntau qis dua 0.25% tseem hu ua cov hlau mos vim nws tsis muaj zog, hardness, thiab softness. Nws feem ntau suav nrog feem ntau cov pa roj carbon zoo tib yam steel thiab ib feem ntawm cov khoom siv zoo carbon steel, feem ntau yog siv rau engineering structural Cheebtsam yam tsis muaj kev kho cua sov, thiab qee qhov yog siv rau cov khoom siv kho tshuab uas yuav tsum tau hnav tsis kam tom qab carburizing thiab lwm yam kev kho cua sov.
2. Lub annealed microstructure ntawm qis carbon steel muaj ferrite thiab ib tug me me ntawm pearlite, nrog qis zog thiab hardness, thiab zoo plasticity thiab toughness. Yog li ntawd, nws muaj qhov txias formability thiab tuaj yeem ua tau txias los ntawm kev siv xws li curling, khoov, thiab stamping. Hom hlau no kuj muaj qhov zoo weldability. Cov pa roj carbon tsawg nrog cov ntsiab lus ntawm cov pa roj carbon ntau li ntawm 0.10% mus rau 0.30% yog ib qho yooj yim rau kev txais ntau yam xws li forging, vuam, thiab txiav, thiab feem ntau siv rau hauv kev tsim cov chains, rivets , bolts, ncej, thiab lwm yam.
