DX51D galvanized hlauyog qhov nrov qis- carbon steel dav siv hauv kev tsim kho, tsheb, thiab cov khoom siv hauv tsev tsim khoom vim nws zoo heev corrosion kuj, yooj, thiab durability.
Nws cov zinc coatings (Z, ZF, ZA, AZ, ZM) muab kev tiv thaiv xeb thiab hnyav ib puag ncig, ua rau nws haum rau ob qho tib si cov qauv thiab cov ntaub ntawv zoo nkauj.
DX51D yog dab tsi?
DX51D yog kub-dip galvanized qis- carbon steel qib raws li EN 10346 tus qauv. Nws yog tsim los rau txias- daim ntawv thov, muab siab plasticity, toughness, thiab weldability.
Kev piav qhia npe:
D: Txias- ua hlau
X: Unspecified dov lub xeev (kub- dov los yog txias- dov)
51: Hlau qib serial tooj; cov lej siab dua (52, 53, 54) qhia tias muaj kev ua tau zoo dua
D: Kub-dip galvanized txheej
+Z, +ZF, +ZA, +AZ, +ZM: Txheej hom
Kev sib piv nrog DX52D
DX52D zoo ib yam li DX51D tab sis nta ntau dua ductility thiab elongation, ua rau nws zoo dua haum rau cov txheej txheem nyuaj. DX51D yog qhov zoo tagnrho rau cov qauv tsim cov ntawv thov uas muaj qhov yooj yim thiab kev tiv thaiv corrosion txaus.

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 lej tsim tus lej qhia txog lub hauv paus hlau nrog qhov tsawg kawg nkaus tawm lub zog feem ntau ≤ 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.
Q2: Dab tsi yog nws cov cuab yeej ua haujlwm tseem ceeb?
A:Raws li EN 10346, cov yam ntxwv raug yog:
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 ≥ 22% - 26% (yam tsawg kawg yog nyob ntawm thickness). 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.
Agricultural thiab industrial ntim.
