Cov pa roj carbon steel kav raws li JIS G3452 tus qauv tsim nyog rau chav dej, dej, roj, roj, cua thiab lwm cov kav dej uas muaj kev ua haujlwm tsawg.
JIS G3452 carbon steel kav yuav tsum tau ua kom tau raws li tej yam khoom uas yuav tsum tau, nrog rau yam tsawg kawg nkaus tus nqi ntawm tensile zog (σb) thiab elongation (δ). Rau qib SGP, lub zog tensile yuav tsum yog tsawg kawg yog 290MPa, thiab qhov elongation yuav tsum yog tsawg kawg yog 30% (rau cov yeeb nkab seem thiab S loj dua los yog sib npaug rau 8 hli longitudinal strips).
JIS G3452 qhia qhov sib txawv ntawm qhov sib txawv ntawm cov kab thiab phab ntsa tuab ntawm cov yeeb nkab steel, nyob ntawm qhov nominal txoj kab uas hla (D) ntawm cov yeeb nkab steel. Piv txwv li, rau cov yeeb nkab steel nrog D=165.2mm, qhov tso cai sib txawv ntawm cov kab sab nraud yog ±0.8mm mus rau ± 1.6mm, thaum qhov sib txawv ntawm phab ntsa thickness yog {{7 }}.5%.
