Galvanized hlau
Lub DX54D finely coated sheet hlau yog tsim rau qhov siab tshaj plaws extensibility, uas yog vim li cas nws yog zoo meej rau ntau yam shaping txheej txheem, xws li cov khoom nws tus kheej los yog qhov tob ntawm kos yog ntau dua li niaj zaus. Nws ntws yooj yim vim nws cov ductility siab thiab, ntawm chav kawm, nws nto, uas yog txawm li ib tug laminate yuav, los pab txhawb khoov ntawm qhov chaw koom nyob rau hauv ib co duab yam tsis muaj, piv txwv li, cracking ntawm lub ntsiab koom nyob rau hauv cov txheej txheem.
Ntau txoj haujlwm tshiab tau ua tiav tsis ntev los no kom DX54D ua raws li cov cai hauv kev lag luam tam sim no thiab tuaj yeem muab cov txiaj ntsig ntawm kev ua siab ntev rau kev ntxhov siab thiab deformation, uas nyob hauv thaj tsam ntawm 140-300 MPa thiab elongation ntawm kwv yees li 36-44%, nyob ntawm qhov tuab ntawm cov ntawv phaj. Nws yog li ntawd tiv taus qhov tseem ceeb deformation yam tsis tau tawg txawm tias thaum lub sij hawm shaping txheej txheem. Tsis tas li ntawd, lub tsho tiv no txuas ntxiv ntawm zinc tiv thaiv qhov chaw los ntawm txhua yam kev xeb txawm tias tom qab cov txheej txheem shaping.
Lub formability thiab cov tswv yim siv los yog rooj plaub tau ua pov thawj tias DX54D yog siv tau zoo tshaj plaws hauv kev tsim thiab tsim cov tsheb, nyob rau hauv siab precision hauv kev nias thiab sib sau yog qhov tseem ceeb. Txij li thaum DX54D tuaj yeem khaws cov roughness thiab mechanical yam ntxwv rau tib lub℃nyob rau hauv sab nraud cuam tshuam, tshwj xeeb tshaj yog cov neeg kho tshuab loadings, nws tau txais kev ntseeg siab ntawm kev lag luam uas xav tau zoo thiab yooj. Qhov no ib leeg lossis kev sib xyaw ua ke ntawm cov yam ntxwv txhim kho kev ua haujlwm zoo thiab txo cov khoom seem, nrog rau kev nce qib hauv kev lag luam thiab kev lag luam kev lag luam mus txog qib siab ntawm kev ua haujlwm.
Cov ntawv thov hauv Automotive thiab Cov Khoom Siv Hauv Tsev
DX54D daim ntawv phaj yog nyiam heev rau ntau yam kev lag luam uas tsim cov khoom siv hauv lub cev thiab cov khoom siv hauv tsev offline xws li tshuab ntxhua khaub ncaws thiab tub yees vim nws qhov tsim tau zoo heev thiab vim tias nws ua tau raws li qhov yuav tsum tau ua ntawm ob qho kev ua tau zoo thiab zoo li ntawm cov khoom tiaj tus.
Cov txiaj ntsig ntawm Corrosion Resistance hauv Galvanized Steel

Qhov zoo ntawm DX54D Steel
High ductility thiab complex formability
Peb cov hlau DX54D muaj cov ductility zoo heev, thiab txawm tias cov duab nyuaj tuaj yeem ua tiav yooj yim yam tsis muaj kev tawg. Piv nrog rau lwm hom, peb DX54D ua tau zoo dua nyob rau hauv txoj kev sib sau thiab muaj peev xwm ua tau raws li qhov xav tau ntawm qhov nyuaj, tshwj xeeb tshaj yog tsim rau kev lag luam xws li tsheb thiab khoom siv hauv tsev.
High - zoo galvanized txheej thiab zoo heev corrosion kuj
Peb siv cov txheej txheem kub kub-dip galvanizing kom ntseeg tau tias cov txheej txheem galvanized ntev thiab ntev - kav ntev. Qhov no ua rau peb cov hlau DX54D muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog haum rau qhov chaw ntub dej lossis sab nraum zoov. Piv nrog rau lwm hom, peb txheej galvanized yog ntau ruaj, uas zoo txhim kho cov kev pab cuam lub neej ntawm cov khoom.
Stable mechanical zog
DX54D steel muaj lub zog tensile zoo ib yam thiab lub zog tawm los, thiab ruaj khov thiab txhim khu kev qha txawm tias muaj kev ntxhov siab thiab tsim. Peb cov khoom tau lees paub tias yuav tsis muaj qhov hloov pauv ntawm kev ua haujlwm ntev - siv sijhawm ntev, yog li zam qhov teeb meem ntawm kev hloov pauv ntau zaus
Kev ua haujlwm vuam zoo heev
Vim yog cov ntsiab lus ntawm cov pa roj carbon tsawg ntawm DX54D steel, qhov vuam kev ua tau zoo heev, thiab yuav luag tsis muaj qhov tawg lossis tawg. Txhawb ntau txoj kev vuam thiab tuaj yeem hloov kho raws li kev xav tau ntau lawm. Piv nrog rau lwm hom, peb cov khoom muaj kev tswj cov cua sov zoo dua thaum lub sij hawm vuam, tsis txhob muaj teeb meem los ntawm overheating.
