Dab tsi yog DX51D thiab DX53D Galvanized Steel?
Galvanized steel yog hais txog hlau uas tau coated nrog ib txheej ntawm zinc los txhim kho corrosion kuj. Daim ntawv thov ntawm zinc txheej tiv thaiv cov hlau substrate los ntawm kev ua raws li lub cev tiv thaiv thiab muab kev tiv thaiv kev txi thaum txheej kev ncaj ncees raug cuam tshuam.
DX51D thiab DX53D yog txias- dov qis- cov qib carbon steel tau teev tseg raws li EN 10346 tus qauv rau cov khoom kub tsis tu ncua -dip coated khoom. DX51D yog optimized rau tag nrho formability zoo thiab sib npaug txhua yam kev ua tau zoo, thaum DX53D lub hom phiaj siab dua uniform elongation thiab sib sib zog nqus- kos formability.
Cov qauv siv thiab cov qauv siv
Ob qib poob raws li European kub-dip coated steel qauv EN 10346 thiab tau dav siv hauv tsev, tsheb, khoom siv, thiab kev siv cov ntaub ntawv dav dav.
Chemical Composition Summary
| Element | DX51D (kwv yees) | DX53D (kwv yees) |
|---|---|---|
| C (Carbon) | Tsawg dua lossis sib npaug li 0.10–0.12% | Tsawg dua lossis sib npaug li 0.10–0.12% |
| Si (Silicon) | Tsawg dua los yog sib npaug li 0.50% | Tsawg dua los yog sib npaug li 0.50% |
| Manganese (Mn) | Tsawg dua lossis sib npaug li 0.60% | Tsawg dua lossis sib npaug li 0.60% |
| P (phosphorus) | Tsawg dua lossis sib npaug li 0.10% | Tsawg dua lossis sib npaug li 0.10% |
| S (Sulfur) | Tsawg dua lossis sib npaug li 0.035–0.045% | Tsawg dua lossis sib npaug li 0.035–0.045% |
Ob qib yog qib qis -carbon txias- dov steels uas tswj tau zoo weldability thiab coating compatibility.

xwm 53dfeem ntau qhia tau hais tias elongation siab dua thiab sib sib zog nqus zoo dua - kos duab kev ua tau zoo dua DX51D, ua rau nws yog ib qho kev xaiv zoo nkauj rau kev ua haujlwm zoo sib xws, thaum DX51D muab ntau lub zog thiab kev ua haujlwm sib luag.
Formability thiab Fabrication sib txawv
DX51D: Zoo dav formability nrog txhim khu kev qha kev ua tau zoo nyob rau hauv yooj yim khoov thiab txheem fabrication txheej txheem.
DX53D: Siab dua li niaj hnub elongation thiab txhim kho anisotropy ua rau nws zoo tagnrho rau kev sib sib zog nqus nqus thiab kev ua haujlwm nyuaj.
Cov kev sib txawv no cuam tshuam cov cuab yeej tsim, springback, thiab cov txheej txheem kev npaj rau cov khoom xws li automotive panels lossis cov khoom siv plhaub.
Weldability thiab ua
Ob leeg DX51D thiab DX53D yog tsawg- carbon steels nrog qis carbon sib npaug qhov tseem ceeb, uas txhais tau tias zoo weldability nrog cov hlau vuam txoj kev. Welders yuav tsum suav rau zinc txheej ntawm qhov sib koom ua ke los tiv thaiv porosity thiab fumes thaum lub sij hawm arc vuam.
Kev tiv thaiv corrosion thiab kev kho deg
Corrosion tsis kam rau ob qho tib si yog muab los ntawm zinc txheej. Cov chav kawm txheej zoo tib yam (piv txwv li, Z275) muab kev tiv thaiv corrosion zoo sib xws rau ob qib - qhov sib txawv ntawm cov hlau hauv paus tsis tuaj yeem hloov corrosion kuj thaum txheej thiab thickness yog tas li.
