Tig-txiav qhov ntsuas rau carbon steel yuav tsum tau hloov kho raws li cov khoom siv cov ntsiab lus carbon, hardness, thiab machining tej yam kev mob. Txiav ceev thiab cov cuab yeej hnav yog qhov tseem ceeb ntawm kev tswj xyuas.
① Tsawg- carbon steel (AISI 1005-1026): Cov khoom siv nrog cov ntsiab lus carbon ntawm 0.06%-0.28% nyiam ua cov chips ntev, xav tau 15%-20% nce hauv kev txiav ceev kom txhim kho qhov chaw tiav. Thaum lub sij hawm roughing, qhov tob ntawm kev txiav tuaj yeem tswj tau ntawm 2-3mm, nrog rau cov nqi tshwj xeeb nyob ntawm cov khoom siv thiab cov khoom ua haujlwm hardness.
② Nruab nrab- carbon steel (AISI 1029-1053): Nyob rau hauv 0.25%-0.55% carbon cov ntsiab lus ntau yam, qhov saum npoo tiav zoo dua li cov hlau tsis tshua muaj carbon, tab sis nws tseem ceeb uas yuav tsum nco ntsoov tias kev txiav ceev yog qhov sib npaug ntawm qhov tawv. Nws raug nquahu kom txo cov kev txiav ceev los ntawm 5% -8% rau txhua 1 HRC nce hardness.
③ Siab- carbon steel (AISI 1055-1095): Cov ntsiab lus carbon txog li 1.03% ua rau muaj zog txiav ntau dua. Qhov tsawg-kev txiav ceev yog qhov zoo dua, thiab siv cov cuab yeej hnav-tiv taus coated tuaj yeem ua rau lub neej ntev dua li 40%.
