S320GD galvanized steel ntawv
Raws li automotive manufacturers tseem ceeb rau kev nyab xeeb, durability, thiab lub teeb yuag tsim, GNEE Steel'sS320GD galvanized steel ntawvtau tshwm sim raws li cov khoom nyiam rau automotive chassis thiab cov khoom siv. Cov txheej txheem qib steel no ua ke nrog kev ua haujlwm tshwj xeeb nrog kev tiv thaiv corrosion, hais txog kev lag luam qhov mob tseem ceeb tshaj plaws rau cov khoom hauv qab.
Ntawm qhov tseem ceeb ntawm S320GD qhov kev thov rov hais dua yog nws qhov sib npaug ntawm lub zog thiab kev tsim tawm - tsis tshua muaj kev sib xyaw ua ke hauv cov qauv galvanized steel. Nrog rau qhov tsawg kawg nkaus lub zog ntawm 320MPa thiab tensile lub zog xws li 360-510MPa, nws muab lub rigidity xav tau los tiv thaiv txoj kev cuam tshuam thiab hnyav loads. Meanwhile, nws elongation tus nqi ntawm ntau dua los yog sib npaug li 20% tso cai rau complex stamping thiab dabtsi yog khoov cov txheej txheem, enabling manufacturers los tsim intricate chassis geometries yam tsis muaj kev cuam tshuam cov qauv kev ncaj ncees.
Cov txheej txheem kub -dip galvanizing (raws li EN 10346) ntxiv txhim kho nws cov nqi rau kev siv tsheb. Cov zinc txheej tsim ib daim ntawv cog lus nruj nrog lub hauv paus hlau, xa mus ntev - lub sij hawm corrosion tsis kam tiv thaiv txoj kev ntsev, noo noo, thiab khib nyiab- ncua kev pab cuam lub neej ntawm chassis Cheebtsam los ntawm 15-20 xyoo piv rau uncoated steel.
Hauv qab no yog cov ncauj lus kom ntxaws ntxaws ntawm S320GD qhov kev ntsuas kev ua haujlwm tseem ceeb rau kev siv tsheb chassis:
| Performance Metric | S320GD specification | Advantage rau Automotive Chassis |
|---|---|---|
| Yam tsawg kawg nkaus Yield Strength | Ntau dua lossis sib npaug li 320MPa | Resistant deformation ntawm txoj kev vibrations thiab cuam tshuam. |
| Tensile zog | 360-510MPa | Tiv thaiv kev puas tsuaj hauv siab - qhov chaw muaj kev ntxhov siab (piv txwv li, ncua kev sib tsoo). |
| Elongation (A80 hli) | Ntau dua lossis sib npaug li 20% | Enables complex stamping ntawm chassis rails thiab crossmembers. |
| Zinc Txheej (Z275) | Ntau dua lossis sib npaug rau 275g / ㎡ (ob npaug-Sided) | Nrog rau 1000+ teev ntsev tsuag- tseem ceeb rau txoj kev caij ntuj no. |
| Weldability | Raws li EN 10346 | Xyuas kom muaj zog, ruaj khov pob qij txha ntawm chassis Cheebtsam. |
"Automotive chassis xav tau cov ntaub ntawv uas tuaj yeem tswj tau ob qho tib si lub zog thiab kev ua tiav, thiab S320GD xa tawm ntawm ob sab," hais tias tus kws tshaj lij ntawm GNEE Steel. "Peb cov neeg siv khoom tau tshaj tawm qhov txo qis ntawm qhov tsis ua haujlwm thiab txo tus nqi kho tom qab hloov mus rau peb cov ntawv S320GD galvanized steel."
GNEE Steel muaj S320GD nyob rau hauv customized thicknesses (0.8{7}}3.0mm) thiab zinc txheej qib (Z180-Z350) kom phim cov kev xav tau ntawm tsheb. Nrog lub peev xwm ntau lawm txhua hli ntawm 3,000 tons rau automotive-qib S320GD, peb xyuas kom meej lub sijhawm ua haujlwm ceev rau kev txiav txim loj.Hu rau peb tam sim no kom thov tus qauv, tshuaj xyuas cov ntaub ntawv qhia ntxaws ntxaws, lossis tau txais lub Hoobkas 2026- nqe lus ncaj qha!
