Cam khwb cia hlau yog cov hlau-carbon alloy nrog ib feem ntawm cov pa roj carbon ntau dua 2.11%. cam khwb cia hlau yog tau los ntawm remelting npua hlau nyob rau hauv lub cub tawg, ntxiv ferroalloy, seem steel, thiab rov qab mus rau lub cub tawg los kho qhov muaj pes tsawg leeg.Grey cam khwb cia hlauthiab ductile hlau yog ob feem ntau siv cam khwb cia hlau los tsim castings.
Tuam Tshoj cov qib cam khwb cia hlau feem ntau yog qhia thiab txawv los ntawm cov khoom siv tshuab. Thawj pawg ntawm cov lej hauv qib qhia qhov tsawg kawg nkaus tensile lub zog (hauv MPa), thiab cov lej thib ob (yog tias muaj) qhia qhov tsawg kawg nkaus elongation ntawm qhov tawg (%). Ob pawg ntawm tus lej raug cais los ntawm tus dash "-".
Tsab ntawv Askiv code ntawm grey cam khwb cia hlau yog HT, qhov twg H yog thawj tsab ntawv ntawm Suav Pinyin (Hui Se) lub ntsiab lus grey; T yog thawj tsab ntawv ntawm Suav Pinyin (Tie) ntawm hlau. Cov lej hauv Suav teb qib grey hlau qhia qhov tsawg kawg nkaus tensile zog (MPa). Piv txwv li, HT250 sawv cev rau grey cam khwb cia hlau nrog lub zog tensile yam tsawg kawg nkaus ntawm 250 MPa.
