DC03 steel qib
Cold Rolled Steel yog dab tsi?
Cold rolled steel yog tsim los ntawm kev ua haujlwm kub dov hlau nyob rau hauv chav tsev kub. Tom qab kub dov, cov hlau yog pickled kom tshem tawm cov nplais thiab tom qab ntawd dhau los ntawm txias dov mills kom ua tiav cov tuab tuab, txhim kho nto tiav, thiab txhim kho cov khoom sib xws. Piv nrog kub dov steel, txias dov steel ntawv thiab coil muab zoo dua flatness, tighter tolerances, thiab superior nto zoo, ua rau lawv zoo tagnrho rau precision forming thiab tsos-sensitive daim ntaub ntawv.
dc03 uayog ib qho kev siv dav siv txias txias steel qib tau teev tseg raws li EN 10130 tus qauv. Nws yog tsim los txhim kho formability piv nrog cov qib lag luam yooj yim, ua rau nws tsim nyog rau kev xav tau ntau dua stamping thiab kos duab ua haujlwm.

DC03 Cold Rolled Steel Qib txhais li cas?
Lub npedc03 uaua raws li tus txheej txheem naming system:
- D- Cov khoom lag luam tiaj tus steel rau kev ua kom txias
- C-Cold dov
- 03- Kos qib zoo
DC03 txias dov hlau yog tshwj xeeb rau kev kos duab sib sib zog nqus thiab ntau txoj kev tsim dua DC01. Nws yog feem ntau nkag rau hauv daim ntawv thiab coil daim ntawv thiab siv rau hauv kev tsim cov txheej txheem uas yuav tsum tau muaj zog dua ductility thiab qis zog.
DC03 Steel Chemical Composition
DC03 yog ib qho qis- carbon steel nrog nruj tswj cov tshuaj txwv kom ntseeg tau zoo formability:
| Element | Cov ntsiab lus siab tshaj (%) |
|---|---|
| Cov pa roj carbon (C) | 0.08 |
| Manganese (Mn) | 0.60 |
| Phosphorus (P) | 0.045 |
| Sulfur (S) | 0.045 |
Cov pa roj carbon tsawg dua piv nrog DC01 txhim kho elongation thiab kos duab kev ua tau zoo.
Mechanical Properties thiab DC03 Yield Strength
DC03 yield zogyog qis dua qhov dav dav -lub hom phiaj txias dov steel, tso cai rau cov khoom kom deform yooj yim dua thaum tsim.
| Khoom | Tus nqi |
|---|---|
| Yield zog | Tsawg dua lossis sib npaug li 240 MPa |
| Tensile zog | 270-370 MPa |
| Elongation | Ntau dua lossis sib npaug li 34% |
Lub zog qis zog ua ke nrog ntau dua elongation ua rau DC03 txias dov steel zoo tagnrho rau stamping, dabtsi yog khoov, thiab sib sib zog nqus nqus kev ua haujlwm nrog txo kev pheej hmoo ntawm kev tawg.
DC03 vs DC01: Qhov txawv ntawm qhov ua tau zoo
DC03 thiab DC01 yog ob qho tib si EN 10130 txias dov steel qib, tab sis lawv tau tsim los rau cov kev cai sib txawv:
| Cov khoom sib piv | dc01 ua | dc03 ua |
|---|---|---|
| Formability | Kev tsim qauv | Daim duab sib sib zog nqus |
| Yield zog | Siab dua | qis |
| Elongation | Txuj | Siab dua |
| Tej kev siv | Panels, brackets | Complex stamped qhov chaw |
DC01 yog qhov tsim nyog rau cov duab yooj yim thiab tus nqi- cov ntawv siv tau yooj yim, thaum DC03 yog qhov nyiam rau cov khoom uas xav tau ntau deformation.
Cov ntawv thov ntawm DC03 Cold Rolled Steel
DC03 steel ntawv thiab kauj yog dav siv hauv:
- Automotive sab hauv Cheebtsam
- Cov khoom vaj khoom tsev nrog cov duab complex
- Hlau enclosures thiab npog
- Cov rooj tog zaum xav tau cov nkhaus nkhaus
- Precision stamped Cheebtsam
Nws cov nplaim du kuj ua rau DC03 haum rau tha xim, galvanizing, thiab lwm yam kev kho deg.
