DX52D + Z

DX52D + Z yog qib txias- rolled steel ntawv los yog cov sawb galvanized steel ntawv los yog siv ntau yam li kev lag luam xws li kev tsim kho thiab hauv tsev. Hauv qab no yog cov lus qhia ntxaws heev:
Txheem: DX52D + Z Ua raws li European Standard E10130 thiab yog cov stamping - galvanized steel ntawv siv rau kev tsim cov stamping seem.
Tshuaj lom neeg tshuaj: DX52D + Z yog qhov qis- cov hlau rau cov khaub ncaws txias. Nws muaj cov ntsiab lus carbon tsawg thiab muaj cov nyiaj me me ntawm manganese, phosphorus, thiab leej faj. Qhov tshwj xeeb muaj pes tsawg sib txawv los ntawm cov chaw tsim khoom thiab cov qauv.
Cov cuab yeej kho tshuab: tawm lub zog RP0.2 yog 140 {}}, tensile muaj 270 mpa, thiab elongation A80 ntau dua lossis sib npaug nrog 26%. Galvanized Txheej: "Z" nyob rau hauv DX52D + Z qhia tau kub-dip Galvanizing, feem ntau ua raws li cov zinc txheej zinc. Piv txwv li, z140 qhia tau tias zinc txheej hnyav hnyav ntawm 140 grams tauj ib lub meter 'square. Zinc Txheej muab cov khoom siv corrosion zoo heev.
Nta: nws ua kom pom tseeb zoo dua, sib sib zog nqus, thiab kev ua kom nruj. Lub zinc txheej yog txhim khu kev qha thiab ruaj, muaj kev tiv thaiv kom muaj xeb thiab txuas ntxiv rau lub neej ntawm cov hlau.
Cov ntawv thov: feem ntau siv hauv kev tsim kho kev tsim kho, xws li cov hlau qauv fabrication; kev lag luam hauv tsev kev lag luam, xws li tub yees thiab tshuab ntxhua khaub ncaws kev tsim khoom; thiab lwm yam teeb kev lag luam, xws li rooj tog thiab kho vajtse.
