Q1: Lub npe "DX51D + Z" txhais li cas?
A:Qhov no yog tus qauv European (EN) tsim rau qib kub -dip galvanized steel qib:
DX:Qhia tias nws yog atxoj kev hlauFeem ntau rau kev siv txias txias.
51:Tus naj npawb tus qauv qhia txog lub hauv paus hlau nrog qhov tsawg kawg nkaus tawm lub zog feem ntau Tsawg dua lossis sib npaug li 280 MPa thiab cov khoom siv tshwj xeeb tsim nyog rau kev tsim.
D:Denotes lubqib ductility. "D" stands rau "Drawing" zoo, qhia tau hais tias zoo rau zoo heev ductility rau sib sib zog nqus daim ntaub ntawv.
+Z:Qhia cov txheej txheem:kub-dip galvanizednrog zinc txheej.

Yield Strength (Re):Feem ntau 140 - 300 MPa (Ceeb Toom: Tsis muaj qhov tshwj xeeb yam tsawg kawg nkaus yuav tsum tau; nws yog raws li lub hauv paus steel chemistry rau formability).
Tensile zog (Rm):270 - 500 MPa.
Elongation (A₈₀):Feem ntau Ntau dua lossis sib npaug li 22% - 26% (yam tsawg kawg nyob ntawm tuab). Qhov siab elongation no yog qhov tseem ceeb rau nws cov formability.
Nws tsis yog lub siab - lub zog steel.Nws tus nqi yog nyob rau hauv nws zoo heev formability thiab corrosion tiv thaiv.
Q3: "Z" txheej yog dab tsi, thiab cov txheej txheem txheej txheem yog dab tsi?
A:Lub "Z" sawv cev rau aloj zinc txheejthov los ntawm cov txheej txheem kub kub -dip galvanizing. Qhov hnyav txheej yog teev los ntawm lub ntsiab lus (piv txwv li, Z140, Z275):
Piv txwv li - DX51D+Z140:Tag nrho cov txheej txheej tsawg kawg yog 140 g / m² (kwv yees . 20 µm ib sab, 40 µm tag nrho). Cov lej feem ntau yog Z100 (lub teeb), Z140 (tus qauv), Z200 / Z225 (hnyav), thiab Z275 (hnyav ntxiv rau qhov chaw hnyav).
Q4: Cov ntawv thov tseem ceeb rau DX51D + Z yog dab tsi?
A:Nws yog cov hlau ua haujlwm rau kev tsim khoom dav dav qhov twg corrosion kuj thiab formability xav tau, tab sistsis siab structural zog. Common siv muaj xws li:
HVAC ductwork thiab cov khoom.
Cov khoom siv hauv tsev (lub tshuab ntxhua khaub ncaws, tshuab ziab khaub ncaws, enclosures).
Lub teeb ntsuas lub tsev panels thiab profiles.
General hlau txee, enclosures, thiab lub teeb rooj tog.
