DX51D yog dab tsi?
DX51D yog qib kub-dip galvanized qis- carbon steel raws li EN 10346, uas feem ntau yog siv rau txias- daim ntawv thov. Nws muaj cov zoo corrosion kuj thiab yooj. Nws feem ntau yog siv rau hauv kev tsim kho, kev tsim tsheb, thiab cov khoom siv hauv tsev vim nws muaj ntau yam.
Kev rhuav tshem DX51D Lub Npe
"D" - Cold Forming Steel
"X" - Unspecified Rolling State. Nws tuaj yeem yog kub- dov los yog txias - dov.
"51" - Hlau Qib Serial Number. Cov lej siab dua (piv txwv li, 52, 53, 54) qhia txog kev tsim tau zoo dua.
"D" - Kub-Dip Galvanized Txheej
"+Z, + ZF, thiab lwm yam." - Txheej hom.
Qhov txawv ntawm DX51D thiab DX52D yog dab tsi?
DX51D thiab DX52D yog ob qho tib si kub-dip galvanized steels siv rau kev sib sau txias. DX52D muaj ntau dua ductility thiab zoo elongation dua DX51D. DX52D yog qhov tsim nyog rau cov txheej txheem tsim cov txheej txheem uas yuav tsum tau ua kom yooj yim dua, thaum DX51D yog siv rau cov qauv tsim daim ntawv thov.

DX53D, DX54D, DX56D thiab DX57D tsis yog- cov hlau tsis muaj hnub nyoog, piv txwv li lawv cov khoom yuav nyob twj ywm tsis hloov yam tsawg kawg rau lub hlis
1) Yog tias tsis muaj cov ntsiab lus qhia tawm tam sim no, 0.2% yield point tus nqi Rp0,2 yog siv. Yog hais tias cov khoom muaj ib tug pronounced yield point, qhov tseem ceeb siv rau qhov qis yield point ReL.
2) DX52D: qhov txwv sab saud no tsuas yog siv rau qhov zoo ntawm Ntob B. Rau qhov zoo A, qhov siab tshaj plaws yog 360 MPa.
3) Txo qhov tsawg kawg nkaus elongation A80 tus nqi rau thickness 0.50mm 4) DX54D: txo qhov tsawg kawg nkaus r90-tus nqi rau cov khoom tuab 1.5mm < t < 2 mm ( rho tawm 0.2 units) thiab t Ntau dua lossis sib npaug li 2 hli ( rho tawm 0.4 units) thov. Tsis tas li ntawd, nyob rau hauv cov ntaub ntawv ntawm ZF txheej qhov tsawg kawg nkaus r90-tus nqi raug txo ( rho tawm 0.2 units). 5) DX56D thiab DX57D txo qhov tsawg kawg nkaus r90-tus nqi rau cov khoom tuab 1.5mm < t < 2 mm ( rho tawm 0.2 units) thiab t Ntau dua lossis sib npaug li 2 hli ( rho tawm 0.4 units) thov. GNEE STEEL qhov kev tswj hwm ntau lawm ua kom txhua lub kauj ntawmDX51D 1.0917 galvanized hlauxa cov txheej tuab zoo ib yam, qhov sib npaug ntawm qhov sib xws, thiab kev ua haujlwm txhua yam - lav ntev - lub sijhawm ua tiav qhov project.
Tsis tas li ntawd, nyob rau hauv cov ntaub ntawv ntawm ZF txheej ob yam tsawg kawg nkaus r90-tus nqi ( rho tawm 0.2 units) thiab yam tsawg kawg nkaus n90-tus nqi ( rho tawm 0.01 units) qis dua thiab ntxiv cov kev txo qis hauv qab no:
- txo qhov tsawg kawg nkaus r90-tus nqi rau cov khoom tuab 0.50mm < t Tsawg dua los yog sib npaug rau 0.70mm ( rho tawm 0.2 units) thiab t Tsawg dua lossis sib npaug li 0.50mm ( rho tawm 0.4 units).
