kub-dip galvanized steel
DX54D yog alloyed kub-dip galvanized steel, uas yog ib hom ntiav-stretched galvanized steel ua tiav nrog DC04 raws li cov khoom siv hauv paus, thiab saum npoo yog plated nrog ib txheej ntawm zinc.
D-Steel Stamping
X-kov dov los yog kub dov
54 - Stamping class (tus lej ntau dua, qhov zoo dua qhov kev ua haujlwm stamping)
D – kub-dip coated steel phaj
Alloyed siab-qib steel DX54D yog muaj nyob rau hauv cov nram qab no kub-dip coatings: DX54D + Z (galvanized), DX54D + ZF (galvanized- hlau), DX54D + ZA (galvanized{10}} txhuas), DX54D + AZ (aluminium-zinc), DX54D + AS (aluminium-silicon-coated).
Kev xav tau ntawm DX54D
Mechanical zog
Txhawm rau ua kom tau raws li qhov xav tau ntawm ultra- kos duab sib sib zog nqus, ntxiv rau qhov tsis muaj zog tawm los thiab siab elongation tau teev nyob rau hauv tus qauv, ntau dua r thiab n qhov tseem ceeb.
Plating
Cov txheej thiab cov substrate yuav tsum muaj zog adhesion, thiab yuav tsum tsis txhob poob thaum lub sij hawm stamping deformation, thiab muaj kev vuam zoo thiab corrosion kuj.
nto
Feem ntau, qhov saum npoo yuav tsum tau ua kom du thiab du kom ntseeg tau tias qhov chaw ci ntsa iab thiab zoo nkauj tom qab pleev xim, thiab muaj qee qhov yuav tsum tau ua rau lub ntsej muag roughness, vim tias nws yuav cuam tshuam rau kev ua haujlwm stamping ntawm cov khoom thiab adhesion ntawm cov xim zaj duab xis.
