Kev lag luam zoo kub dip galvanized steel yog ib hom hlau uas tuaj yeem ua tom qab galvanizing ib kauj ntawm SPCC txias dov khoom. Zinc txheej thickness yog raws li thickness thiab dav thiab yog tswj los ntawm JIS G 3302.
Dimensional Yam ntxwv ntawm SGCC Steels: Lub thickness siv tau rau cov khoom siv SGCC raws li tau teev tseg hauv JIS G3302 pib los ntawm 1.6 hli mus rau 3.2 hli. Txawm li cas los xij, qhov dav ntawm SGCC cov khoom siv ntau tshaj 1600 hli.
Lub Chemical Composition ntawm SGCC Steels: JIS G 3302 txhais cov tshuaj muaj pes tsawg leeg ntawm SGCC steels raws li hauv qab no:
Qhov feem pua siab tshaj ntawm cov pa roj carbon (C) yog 0.15 feem pua.
Qhov feem pua siab tshaj ntawm Manganese (Mn) yog 0.80 feem pua.
Qhov feem pua siab tshaj ntawm Phosphorous (P) yog 0.050 feem pua.
Qhov feem pua siab tshaj plaws ntawm Sulfur (S) yog 0.080 feem pua.
Cov seem yog hlau (Fe) feem pua thiab nrog ob peb qhov tsis zoo.
Mechanical Properties of SGCC Steels: Lub zog tensile ntawm SGCC Steels yog qhia nyob rau hauv Newton ib millimeters thiab nws yuav tsum yog tsawg kawg yog 270 N / mm2 (MPa).
Cov cuab yeej elongation ntawm SGCC tsis tau txhais.
Lub hardness ntawm SGCC cov ntaub ntawv kuj tsis raws nraim txhais nyob rau hauv JIS G 3302; Txawm li cas los xij raws li kev nkag siab nws yuav tsum tsawg dua 65 HRB.
Galvanized steel yog hais txog cov pa roj carbon zoo tib yam siv hlau tom qab kev ua haujlwm galvanized tuaj yeem tiv thaiv cov hlau xeb thiab xeb kom ntev lub neej kev pab cuam ntawm cov hlau, suav nrog galvanized galvanized thiab kub dip galvanized. Feem ntau yog siv rau kev tsim cov phab ntsa sab nrauv, xws li iav kab hlau rhuav phab ntsa, marble curtain phab ntsa, aluminium curtain phab ntsa los ua txhua kab thiab cov ntaub ntawv kev ntxhov siab, los yog siv rau sab nraum zoov kev sib txuas lus ntauwd, txoj kev loj thiab lwm yam qhib cua siv hlau hu ua galvanized steel, uas galvanized: hluav taws xob galvanized thiab kub dip galvanized.
