DC05 steel yog qhov zoo tshaj plaws ultra-tshaj tawm qhov txias txias dov steel qibtxhais los ntawm European tus qauv EN 10130: 2006 (Cov Khoom No. 1.0312). Renowned rau nws qhov tshwj xeeb formability, ultra- carbon muaj pes tsawg leeg, thiab superior nto zoo, DC05 yog engineered los tiv thaiv huab cua txias ua hauj lwm yam tsis muaj cracking, wrinkling, los yog springback.
1.Dab tsi yog DC05 steel?
DC05 yog qhov siab tshaj plaws - ua lag luam sib sib zog nqus kos duab txias dov hlau hauv EN 10130: 2006 series, sawv cev rau qhov kawg ntawm cov tshuab txias txias. Lub npe convention raws li nruj kev lag luam logic:
"DC": Sawv rauTeeb duab txias(txias txoj kev zoo), tus qauv tsim los ntawm EN 10130 thiab thoob ntiaj teb lees paub hauv kev lag luam steel.
"05": Qhia txog nws qhov kev ntaus nqi ultra- tob tob. Tsis zoo li cov qib qis (DC01-DC04), tus lej "05" qhia txog DC05 txoj haujlwm tshwj xeeb hauv qhov chaw qab zib ntawm siab -kawg tsheb thiab khoom siv hluav taws xob- nws muab cov neeg tseem ceeb formability thaum tswj tus nqi zoo.
2. Tshuaj muaj pes tsawg leeg
DC05 qhov kev ua tau zoo tshaj plaws yog los ntawm nws cov ultra- cov pa roj carbon tsawg thiab impurity cov ntsiab lus, ib qho muaj pes tsawg leeg uas ua rau nws yog ib qho "purest" txias dov steels hauv kev siv. Kev tswj tshuaj nruj nruj yog lub hauv paus ntawm nws cov qauv microscopic, uas ncaj qha dictates nws cov peev xwm tsim.
| Element | Cov ntsiab lus txwv (EN 10130: 2006) | Core Functional Impact |
|---|---|---|
| Cov pa roj carbon (C) | Tsawg dua lossis sib npaug li 0.008% | Minimizes ua hauj lwm hardening; Ua kom huab elongation mus txog 46% |
| Manganese (Mn) | Tsawg dua lossis sib npaug li 0.30% | Tiv thaiv brittleness; ua kom zoo deformation |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.020% | Txo cov nplej ciam teb brittleness; txhim khu qhov smoothness |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.02% | Txo qhov tsis yog{0}}cov khoom siv hlau; tshem tawm qhov tsis xws luag |
| Txhuas Txhuas (Alt) | Ntau dua lossis sib npaug li 0.015% | Refines grain qauv; stabilizes sib sib zog nqus kev ua tau zoo |
| Titanium (Ti) | Tsawg dua lossis sib npaug li 0.02% | Txhim kho carbon atoms; txhim kho kev laus tiv thaiv |
Qhov no yog qhov tseeb metallurgical tsim tsim ib qho tshwj xeeb microstructure: DC05's ferrite nplej yog teem rau hauv ib qho kev txiav txim siab, nplua - cov qauv ntim (cov nplej loj txog li 12μm ntawm qhov nruab nrab). Nyob rau hauv sib piv, impurities raug txwv kom tsawg tshaj li 10 inclusions ib square millimeter. Cov qauv "huv" no tso cai rau cov nplej kom swb sib haum xeeb thaum lub sij hawm stamping, tsis txhob muaj kev ntxhov siab thiab ua kom tsis muaj qhov tawg hauv qhov sib sib zog nqus - cov txheej txheem kos duab.
3. Mechanical Properties
DC05's mechanical properties yog masterclass hauv cov khoom siv engineering, zoo kawg nkaus sib npaug qis tawm lub zog nrog siab elongation -ib qho tseem ceeb ua ke rau ultra- kos duab tob.
| Khoom | DC05 Tus Qauv Tus Nqi (EN 10130: 2006) | Qhov tseem ceeb |
|---|---|---|
| Yield zog (Rp0.2) | 120-180 MPa | Tsawg tsim quab yuam yuav tsum tau; extends tuag lub neej |
| Tensile zog (Rm) | 270-330 MPa | Ua kom muaj zog ntawm cov qauv tom qab tsim |
| Elongation (A80 hli) | Ntau dua lossis sib npaug li 38% (Tswj: 40-46%) | Ua kom pom kev sib sib zog nqus heev yam tsis muaj thinning |
| Plastic Strain Ratio (r-tus nqi, r90) | Ntau dua lossis sib npaug rau 1.9 | Tiv thaiv cov ntaub ntawv thinning thaum kos duab; tseem ceeb heev rau cov duab complex |
| Strin Hardening Exponent (n{0}}tus nqi) | Ntau dua lossis sib npaug li 0.20 | Xyuas kom muaj kev sib haum xeeb deformation thoob plaws qhov chaw |
Qhov tseem ceeb ntawm cov lej no nyob hauv lawv qhov kev sib koom ua ke. Lub zog tawm los qis li 120 MPa txo qhov siab ntawm stamping tuag, thaum qhov elongation tus nqi txog li 46% tso cai rau DC05 mus rau qhov ntev 1.46 npaug ntawm nws qhov loj me. Qhov kev sib xyaw ua ke tshwj xeeb no yog qhov ua rau DC05 hloov tsis tau rau qhov chaw xws li tsheb roj tso tsheb hlau luam thiab lub tub yees plhaub, uas yuav tsum muaj kev ncab hnyav.

| FC (Qib siab) | Ib sab dawb tsis pom kev tsis xws luag, lwm tus ntsib FB | Semi- pom cov khoom siv |
| FD (Super Qib Siab) | Ib sab flawless rau painting / electroplating, lwm yam raws li FB | Automotive sab nrauv panels, hwm cov khoom siv plhaub |
Nto Roughness (Ra): Tswj ntawm 0.6–1.0μm, ua kom muaj daim iav -zoo li tiav. Tom qab electroplating, lub ntsej muag gloss tseem qis dua 20GU, tus qauv uas ua tau raws li cov kev xav tau zoo nkauj tshaj plaws rau cov khoom siv siab tshaj - kawg.
6. Cov qauv thoob ntiaj teb
DC05 tau lees paub thoob ntiaj teb, nrog cov qauv sib npaug thoob ntiaj teb cov tshuab loj, ua rau nws yog cov khoom siv thoob ntiaj teb tiag tiag rau kev lag luam thoob ntiaj teb.
| International Standard | Qib sib npaug | Qhov txawv tseem ceeb |
|---|---|---|
| Tuam Tshoj (GB/T 5213) | 08# | Zoo sib xws, DC05 muaj ntau dua r-tus nqi |
| EU (EN 10130) | DC05 (1.0312) | Tus qauv qub |
| Nyiv (JIS G3141) | SPCF | elongation qis dua DC05 |
| USA (ASTM) | CR4 | Automotive-qib sib npaug |
Qhov tseem ceeb, DC05 phim qhov kev ua tau zoo ntawm cov qib thoob ntiaj teb xws li CRA thiab DDS (Drawing Dimple Steel). Nws r- tus nqi (plastic strain ratio) yog 0.2 siab tshaj qhov ntsuas thoob ntiaj teb, ua pov thawj rau qhov zoo ntawm cov cuab yeej siv hlau hauv tsev.
