Txhais
DX: Thawj tsab ntawv D sawv cev rau cov hlau tiaj tus rau kev ua kom txias, thiab tsab ntawv thib ob X yog hais tias lub xeev dov ntawm lub substrate tsis tau teev tseg.
51 ~ 57: Cov naj npawb qhia cov qib steel serial tooj; D tom qab ob tus lej yog tus lej ntawm kub-dip galvanizing. Z txhais tau hais tias cov txheej yog zinc ntshiab, ZF txhais tau tias galvanized hlau alloy, AZ txhais tau tias galvanized zinc.
DX51D yog tus qauv European, galvanized nrog 51 steel coil raw khoom, sib npaug rau SGCC. DX51D yog hais txog kev khoov thiab tsim qib galvanized steel coil ntawv, steel qib serial tooj yog 51, nrog qis carbon steel raws li cov khoom siv hauv paus.
Chemical Composition Ntawm DX51D Steel
DX51D yog ib daim ntawv galvanized ntawm dabtsi yog khoov thiab ua qib, steel qib serial tooj yog 51, nrog tsawg carbon steel raws li lub hauv paus khoom.
Steel qib serial tooj 52-56 yog steel daim hlau los yog strips rau stamping.
Lub ntsiab chemical Cheebtsam ntawm DX51D yog raws li nram no:
