DC04 Cold Rolled Steel Chev: Ib qho Catalyst rau Automotive Lightweighting
Automotive lightweighting yog lub tswv yim tseem ceeb rau kev txo cov roj noj thiab txo cov pa roj carbon emissions, nrog rau txhua txhua 10% txo cov tsheb hnyav txhim kho roj efficiency los ntawm 6-8%. DC04 txias dov steel coil plays lub luag haujlwm tseem ceeb hauv qhov kev pib no, ua tsaug rau nws cov khoom siv tshwj xeeb uas tso cai rau kev siv lub ntsuas me me thaum tswj kev ua haujlwm.
| Lub teeb yuag Metric | DC04 Cold Rolled Steel Chev | Kev cuam tshuam rau Automotive Performance |
|---|---|---|
| Thickness Ntau | 0.16-1.2 hli | Ua kom siv cov ntsuas nyias nyias thiab cov khoom siv ib txwm muaj, txo qhov hnyav ntawm 15-20% |
| Lub zog tshwj xeeb | Siab (lub zog tensile 270-410 MPa) | Ua kom muaj kev ncaj ncees nrog cov khoom ntim tsawg |
| Formability rau nyias Gauges | Zoo heev (elongation Ntau dua lossis sib npaug li 38%) | Tso cai sib sib zog nqus- kos duab nyias - ntsuas cov khoom yam tsis muaj kev tawg |
| Qhov hnyav ntawm ib feem | Txog li 30% rau cov khoom sib xyaw | Ncaj qha txhim kho roj efficiency thiab txuas ntxiv EV roj teeb ntau |
Tsis zoo li hnyav dua - dov steel lossis lwm cov ntaub ntawv xws li txhuas (uas ua rau muaj kev sib tw thiab cov nqi sib tw), DC04 txias dov steel kauj muaj tus nqi - siv lub teeb yuag. Nws muaj peev xwm muab dov rau hauv ultra- cov ntsuas nyias (mus txog 0.16mm) thaum khaws cov ductility tshwj xeeb txhais tau hais tias cov neeg tsim khoom tuaj yeem hloov cov khoom tuab, hnyav dua nrog DC04 yam tsis muaj lub zog lossis kev tsim kho. Piv txwv li, siv 0.5mm DC04 txias dov steel coil rau automotive puab panels txo qhov hnyav los ntawm ntau tshaj 30% piv rau cov tsoos 0.8mm kub-rolled steel, thaum tseem ua tau raws li qhov yuav tsum tau crashworthiness thiab durability.
