Qhov thib ob, qhov feem pua ntawm carbon nyob rau hauv cam khwb cia hlau yog dab tsi? Feem ntau cam khwb cia hlau muaj cov tshuaj muaj pes tsawg leeg ntawm 2.5-4.0% carbon 1-3% silicon, thiab lwm yam hlau.

Tom qab ntawd, ib tus tuaj yeem nug, qhov feem pua ntawm cov pa roj carbon hauv npua hlau yog dab tsi?

3.5 - 4.5%

Qhov twg los ntawm cov hlau muaj qhov siab tshaj plaws ntawm cov pa roj carbon?

Cam khwb cia hlau nrog 4.2% carbon yog carbon ntau ua tau, vim 4.2% yog solubility txwv rau carbon hauv hlau.
