galvanized hlau
DX54D yog kub-dip coated sib sib zog nqus- kos hlau nyob rau hauv DX series, muaj nuj nqis rau siab formability. Ua los ntawm qis- carbon steel, nws zoo tagnrho rau kev sib sau txias. "DX" qhia cov koob, "54" qib formability, thiab "D" qhov tob- kos duab zoo. Ob leeg DX54D thiab DX53D yog cov tsheb hlau, tab sis DX54D muaj ntau dua formability, ua rau nws zoo dua rau cov duab complex. DX54D (sib npaug rau FeP06G, steel tooj 1.0952) yog siv nyob rau hauv automotive panels thiab cov khoom vaj tse, nrog corrosion kuj rau sab nraum zoov los yog ntub dej.
Tshawb nrhiav cov tshuaj muaj pes tsawg leeg ntawm DX54D
DX54D yog ib pawg neeg tseem ceeb ntawm galvanized steel uas tshuav nws cov yam ntxwv tshwj xeeb rau cov tshuaj lom neeg tshwj xeeb ntawm cov hlau. Raws li tus qauv tau teev tseg, nws cov khoom muaj xws li cov hauv qab no nyob rau hauv cov kev txwv muab:
- C (Carbon): siab tshaj 0.12%
- Mn (Manganese): siab tshaj 0.60%
- P (phosphorus): siab tshaj 0.10%
- S (Sulfur): siab tshaj 0.045%
- Al (Aluminium): yam tsawg kawg nkaus 0.015% (qhov no yog ntxiv rau deoxidation thiab pab nyob rau hauv formability)
- Si (Silicon): siab tshaj 0.50%
Xws li cov tshuaj sib npaug tuaj yeem khaws cov hlau zoo heev, ua rau nws siv tau rau hauv kev ua haujlwm sib sib zog nqus nrog kev ua kom ruaj khov thiab hnav los yog corrosion kuj vim zinc txheej. Tsis tas li ntawd, koom nrog cov ntsiab lus no hauv cov khoom me me txhawm rau txhim kho qhov weldability ntawm DX54D thiab pleev xim rau nws daim ntawv thov zoo hauv ntau lub hom phiaj.
Ntxiv rau cov ntsiab lus tseem ceeb, galvanization yog cov txheej txheem kev tiv thaiv xeb vim tias txheej zinc coats cov hlau. Cov ntsiab lus zinc yog muab nyob rau hauv cov kev txwv tshwj xeeb hauv kev lag luam tseem ceeb, xws li EN 10346, uas ua rau nws npaj rau kev ua haujlwm sab hauv tsev thiab sab nraum zoov. Cov yam ntxwv ntawm cov tshuaj muaj pes tsawg leeg tau lees paub qhov tsim nyog ntawm DX54D daim ntawv phaj hauv high-kawg industries.

Nruab nrab Tensile thiab Yield Strength: Muab lub zog txaus rau kev ua haujlwm ntev yam tsis muaj kev cuam tshuam kev tsim kho, haum rau tsheb thiab khoom siv.
High Elongation: Tso cai stretching tseem ceeb, ua kom cov duab tsis muaj cracking.
Zoo Anisotropy (R-Value): Ua kom cov khoom sib xws hauv cov lus qhia sib txawv, txo qhov tsis xws luag hauv qhov sib sib zog nqus- kos.
Stable Strain Hardening Index (n-Tus nqi): Txhawb gradual deformation, uas pab tswj cov txheej txheem kev ncaj ncees thaum lub sij hawm shaping.
