Xov xwm zoo tuaj tias Tsib txhiab tons ntawm carbon steel coils raug xa mus rau Mexico.
Cov pa roj carbon ntau, feem ntau hu ua cov cuab yeej hlau, muaj los ntawm {{{0}}.60 feem pua rau 1.70 feem pua carbon thiab tuaj yeem ua kom tawv thiab tempered. Raws li cov khoom lag luam zoo, nws tau muab faib ua cov pa roj carbon zoo tib yam thiab cov khoom siv zoo carbon steel. Kub ua hauj lwm zoo thiab txiav kev ua tau zoo, kev vuam tsis zoo. Lub zog thiab hardness yog siab dua li cov pa roj carbon tsawg, thaum lub plasticity thiab toughness yog qis dua cov pa roj carbon tsawg. Tsis muaj kev kho cua sov, ncaj qha siv cov khoom kub dov, cov khoom siv txias txias, tuaj yeem siv tom qab kev kho cua sov. Cov quenched thiab tempered nruab nrab carbon steel muaj cov khoom zoo txhua yam. Yog li ntawd, nyob rau hauv ntau yam kev siv ntawm nruab nrab lub zog theem, nruab nrab carbon steel yog feem ntau lug siv, nyob rau hauv tas li ntawd mus raws li ib tug lub tsev cov ntaub ntawv, tab sis kuj ib tug loj tus naj npawb ntawm siv nyob rau hauv tsim ntawm ntau yam mechanical qhov chaw. Cov pa roj carbon tsawg, tseem hu ua cov hlau me me, muaj cov ntsiab lus carbon ntawm 0.10 feem pua rau 0.30 feem pua. Cov pa roj carbon tsawg yog ib qho yooj yim rau kev lees txais txhua yam kev ua haujlwm xws li forging, vuam thiab txiav, thiab feem ntau siv rau hauv kev tsim cov chains, rivets, bolts, shafts thiab lwm yam.
