Ikhoyili yentsimbi ebandayo eqengqelekileyo DC01 DC03 DC04 DC06
Ngomzobo ogqwesileyo kunye nokusebenza kwe-welding kunye nokuchaneka okuphezulu okuphezulu, iklodi eqengqele ikhabhoni esezantsi kunye neepleyiti zentsimbi zecarbon eziphantsi kakhulu ezinikezwe nguMittel zisetyenziswe ngokubanzi ekwenzeni iindawo ezahlukeneyo zemoto. Ngokwe-ductility, i-DC04 (i-St14, i-St15) ikhabhoni esezantsi kunye neepleyiti zentsimbi ze-carbon ezisezantsi zilungele ukwenza, ukugoba okanye ukuwelda ngokulula.
DC04 (St14, St15) ikhabhoni ephantsi kunye ne-ultra-low carbon automotive steel mechanical and process performance:

ukuthatha i-RP0.2 kwimeko yesivuno esingacacanga, kungenjalo i-ReL.
cr = (r90 + 2r45 + r0) / 4; n = (n90 + 2n45 + n0) / 4.
DC04 (St14, St15) ikhabhoni esezantsi kunye neecarbon ezisezantsi zecarbon ezisebenzisa iipleyiti zentsimbi:
Ubungakanani bokuzibiza: 0.30mm ~ 0.35mm, ububanzi begama: 700mm ~ 1850mm.
DC04 (St14, St15) ikhabhoni esezantsi kunye ne-ultra-low carbon car automens strain strain mark:
Kuqinisekisiwe ukuba akukho phawu lokuxinana luvela kwiipleyiti zentsimbi kunye nemicu kwisicelo sazo kwiinyanga ezi-6 emva kokuba zivelisiwe kwaye kwimeko yokugcina igumbi lobushushu.

IBakala | Ikhowudi No. |
| Iimbonakalo | Ngokulinganayo umphezulu wokugqiba umphezulu | FB (O3) |
| Kuyavunyelwa ubukho beziphene zomhlaba ezimbalwa ezingazukuchaphazela ukuyila kunye nokutyabeka kunye nokuncamathela kwesingxobo njengokuncipha okuncinci, umbono, umngxunya, uphawu lokuqengqeleka kunye ne-oxidation tint. | Ukugqiba umgangatho ophezulu | FC (O4) |
| Icala lomgangatho olungileyo likhululekile nasiphi na isiphene esibonakalayo kwaye elinye icala kufuneka lifikelele kwiimfuno ze-FB ubuncinci. | Umgangatho wokugqiba umgangatho ophezulu | FD (O5) |
