Dab tsi yog cov khoom siv qib ntawmDX53D + ZGalvanized steel?
DX53D + Z yog qhov kub-dip galvanized steel txheej txheem hauv qab European tus qauv (en 10346), uas belongs ua lag luam qib highability galvanized steel:
DX: Kev lag luam qib kub-dip galvanized steel code
53: Qib Formability (Cov Teeb Duab Sib Dag Zoo dua DX51D \/ DX52D)
D: kub-dip galvanized (kub-dip galvanized)
+ Z: ntshiab zinc txheej (gi)
Cov Qauv Txheej Txheem: EN 10346 (coj mus rau DC53D + Z hauv lub teb chaws tus qauv GB \/ T 2518)

DX53D + z yuav galvanized steel xeb?
DX53D + z yuav xeb, tab sis nws zinc txheej yuav ua kom qeeb qeeb hauv cov txheej txheem xeb. Qhov tshwj xeeb los tiv thaiv kev ua tau ntawm xeb nyob ntawm qhov hnyav txiav, kev siv ib puag ncig thiab txoj kev txij nkawm.
DX53D + z siv cov kub-dip ntshiab zinc (gi)
Nws tuaj yeem tiv thaiv xeb tau ntev raws li kev siv tsim nyog siv. Thov Nco Ntsoov:
Rau ib puag ncig ib puag ncig (c 1- C3), xaiv Z90 Txheej, uas tuaj yeem kav rau {3}} xyoo
Rau cov neeg siab cev ib puag ncig (c 4- C5), z 120+ Daim txheej ua si lossis zinc-magnesium
Zam kev puas tsuaj rau kev puas tsuaj thiab cov kua qaub-hauv paus tiv thaiv, thiab kos thiab tswj kom tsis tu ncua
Dab tsi yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm DX53DZ?
