SGCC Galvanized Coil Khoom

SGCC steel yog dab tsi? SGCC steel yog cov khoom muag muag zoo kub-dip galvanized steel. SGCC yog cov khoom siv qib thiab cov npe tau teev tseg hauv JIS G 3302 tus qauv. JIS G 3302 yog cov khoom siv Japanese rau kub-dip galvanized steel. Kev lag luam zoo kub dip galvanized steel yog ib hom hlau ua los ntawm galvanizing coils ntawm SPCC txias dov khoom. Galvanizing thickness yog raws li thickness thiab dav thiab yog tswj los ntawm JIS G 3302.

Tshuaj muaj pes tsawg leeg ntawm SGCC steel: JIS G 3302 txhais cov tshuaj muaj pes tsawg leeg ntawm SGCC steel li:

Qhov siab tshaj plaws ntawm cov pa roj carbon (C) yog 0.15%.

Qhov siab tshaj plaws feem pua ​​​​ntawm manganese (Mn) yog 0.80%.

Qhov siab tshaj plaws ntawm phosphorus (P) yog 0.050%.

Qhov feem pua ​​​​siab tshaj plaws ntawm leej faj (S) yog 0.080%.

Dab tsi tseem tshuav yog cov hlau (Fe) feem pua, thiab cov impurities muaj tsawg heev uas lawv tuaj yeem tsis quav ntsej.

Cov khoom siv ntawm SGCC steel: Lub zog tensile ntawm SGCC steel yog qhia hauv Newtons / mm thiab yuav tsum yog tsawg kawg yog 270 N / mm2 (MPa).

Cov khoom elongation ntawm SGCC tsis tau txhais.

Lub hardness ntawm SGCC cov ntaub ntawv tseem tsis tau meej meej nyob rau hauv JIS G 3302; Txawm li cas los xij, nws tau nkag siab tias nws yuav tsum tsawg dua 65 HRB.
