Dab tsi yog cov khoom siv DX52D + Z?
A: Nws yog European EN tus qauv kub-dip galvanized kauj / ntawv, txias -rolled substrate kub-dip galvanized khoom, belongs rau cov qib stamping galvanized ntawv.
Suav qib dab tsi DX52D + Z sib haum rau?
A: Nws sib haum rau GB tus qauv DC52D + Z. Lawv qhov kev ua tau zoo thiab kev siv cov xwm txheej yog qhov pib zoo ib yam.
Cov tsiaj ntawv / tus lej hauv qib txhais li cas?
A: D=kub-dip galvanized txheej, X=txias- dov substrate, 52=qib zog (siab elongation dua qib 51), + Z=ntshiab zinc txheej (txawv ntawm + AZ aluminium-zinc txheej).
Dab tsi yog qhov txawv ntawm DX52D + Z thiab DX51D + Z?
A: DX52D + Z muaj qhov elongation siab dua (feem ntau Ntau dua lossis sib npaug li 30%), tsim nyog rau cov txheej txheem stamping ntau dua. DX51D + Z yog qib kev lag luam dav dav.
Dab tsi yog lub zog tensile ntau ntawm DX52D + Z?
A: Feem ntau, nws yog 270-410MPa, tab sis tus nqi tshwj xeeb nyob ntawm cov hlau zeb daim ntawv pov thawj zoo.
