In general, hlau is referred to as 'Carbon Steel' where the main alloying component used is Carbon and when no other elemental requirement is specified; i.e., Chromium, Cobalt, Nickel. Carbon Steel can be divided into two categories as, high and low Carbon Steel. Just as the names suggests, High carbon steel contains a higher amount of carbon, and low carbon steel contains a low percentage of carbon. Mild Steel is a form of low Carbon Steel. The qhov sib txawv loj between Carbon Steel and Mild Steel is that Carbon Steel muaj cov pa roj carbon ntau dua whereas Mild Steel muaj cov pa roj carbon tsawg.
Carbon Steel yog dab tsi
Usually, Carbon Steel contains about 0.05-1.70 feem pua carbon los ntawm qhov hnyav. Increasing the carbon percentage in steel gives it additional strength and it is also considered as the most economical approach of increasing the strength of steel. However, as a result of adding more carbon, the steel also tends to become brittle and less ductile. Therefore, the right balance of carbon has to be added in order to achieve extra performing steel. High Carbon Steel has a Cov ntsiab lus carbon ntawm 0.3-1.70 feem pua, and Tsawg Carbon Steel has a Cov ntsiab lus carbon 0.05-0.15 feem pua. Tsawg Carbon Steel yog hom hlau feem ntau siv niaj hnub no vim yog tus nqi tsim khoom tsawg.
Cov pa roj carbon ntau tuaj yeem raug 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; yog Sulphur. Qee qhov kev siv ntawm cov pa roj carbon siab steel muaj xws li; rail steels, pre-stressed qhob, hlau hlua, lub log tsheb, riam, saw hniav, iav log, chains, thiab lwm yam.
Dab tsi yog Mild Steel
Cov hlau me me yog cov pa roj carbon tsawg tshaj plaws thiab muaj qhov sib piv qis ntawm carbon. Cov hlau me me kuj tseem tuaj yeem muaj lwm cov ntsiab lus xws li manganese, silicon thiab cov lej ntawm phosphorous. Cov ntsiab lus ntxiv no tiv thaiv kev ncaj ncees ntawm cov qauv ntawm cov hlau hlau los ntawm kev tiv thaiv kev tsis sib haum xeeb hauv cov hlau muaju. Carbon ua raws li ib tug hardening neeg sawv cev, thiab cov feem pua ntawm cov carbon ntxiv yog ncaj qha proportional rau lub zog ntawm steel; lub zog ntawm cov hlau feem ntau nce nrog feem pua ntawm carbon ntxiv.
Cov hlau me me yog cov hlau dav tshaj plaws thiab siv hauv 85 feem pua ntawm tag nrho cov khoom hlau hauv Tebchaws Meskas ib leeg. Nws tau dhau los ua ib daim ntawv nrov ntawm cov hlau vim nws cov khoom tsim nyog xws li ductility, lub zog thiab tus nqi pheej yig. Cov hlau me me feem ntau yog siv los tsim cov xov hlau, cov ntawv hlau thiab lwm yam khoom siv hauv tsev.
Qhov sib txawv ntawm Carbon Steel thiab Mild Steel
Txhais
In general, Carbon Steel has a higher amount of carbon.
Mild Steel has a relatively low amount of carbon.
Cov ntsiab lus carbon
Cov pa roj carbon steel tuaj yeem muaj qhov hnyav feem pua ntawm cov pa roj carbon ntau li ntawm 0.05-1.70 feem pua .
Mild Steel has a carbon content of 0.05-0.25 percent by weight.
Nqe
Carbon Steel kim dua.
Mild Steel yog pheej yig dua
Cov khoom
Carbon Steel is stronger than Mild Steel. It is also brittle and can break easily when compared to Mild Steel.
Mild Steel tuaj yeem yooj yim welded rau hauv cov duab sib txawv vim nws cov khoom softer thiab tsis muaj zog.
Kev kho cua sov
Carbon Steel tuaj yeem ua tiav kev kho cua sov.
Mild Steel tsis tuaj yeem ua tiav kev kho cua sov.
