DC01 Steel yog dab tsi?
DC01 steel (tus qauv naj npawb 1.0330) yog txias- dov, qis-carbon, tsis yog- alloy zoo hlau txhais raws li EN 10130 tus qauv. Nws belongs rau tsev neeg "DC" rau kev tsim khaub thuas - "DC" sawv cev rau "Drawing Cold," thaum "01" qhia qib pib ntawm tsev neeg no. DC01 yog tsim los ua cov ntawv tiaj tus lossis cov coils los ntawm kev sib tw txias, ua rau cov tuab tuab, du nto tiav, thiab zoo sib xws.
Raws li qhov dav dav -lub hom phiaj txias- dov steel, DC01 muaj qhov sib npaug ntawm cov khoom siv dag zog, ductility, thiab nto zoo - ua rau nws tsim nyog rau ntau yam kev tsim, stamping, thiab kev tsim cov ntawv thov.
DC01 sawv cev rau qib pib ntawm DC tsev neeg hlau thiab tseem paub nyob rau hauv cov npe qub St12 lossis FeP01. Cov qib no tuaj yeem siv rau kev ua haujlwm yooj yim xws li khoov, npib, hlaws thiab kos duab.DC 01 - xa thov!
Chemical Composition & Standards
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm DC01 steel (ib EN 10130) yog ua tib zoo tswj kom ntseeg tau tias qhov kev xav tau txias txias - tsim thiab cov khoom siv kho tshuab. Cov nqi siab tshaj plaws yog:
| Element | Max. Cov ntsiab lus (% los ntawm qhov hnyav) |
|---|---|
| Cov pa roj carbon (C) | 0.12 (trends.directindustry.com) |
| Manganese (Mn) | 0.60 (European Steel Business Group) |
| Phosphorus (P) | 0.045 (trends.directindustry.com) |
| Sulfur (S) | 0.045 (trends.directindustry.com) |
| Silicon (Si) (yog tias muaj) | feem ntau qis / tsawg (steelnumber.com) |
Qhov no qis -carbon, qis- alloy muaj pes tsawg leeg ua kom ntseeg tau tias DC01 tseem khov thiab tsim tau yooj yim, thaum tuav lub zog siv tau rau ntau qhov kev tsim khoom.
Mechanical Properties
Raws li EN 10130 specification, DC01 steel feem ntau nthuav tawm cov khoom nram qab no:
| Khoom | Hom kab mob |
|---|---|
| Yield zog (0.2% offset) | 140-280 MPa (SteelPro) |
| Tensile zog | 270 - 410 MPa (Gnee Steel (tianjin) Co., Ltd) |
| Elongation ntawm Break (A80) | Ntau dua lossis sib npaug li 28% (Salzgitter Flachstahl GmbH) |
| Hardness (Brinell / Rockwell) | ~ 85 - 120 HB (kwv yees. HRB 50 - 70) (opusteel) |
Cov khoom no muaj qhov sib npaug zoo ntawm lub zog, ductility thiab formability - ua rau DC01 ua tiav los ntawm kev khoov, kos duab, stamping, thiab lwm yam txias - ua haujlwm yam tsis muaj kev tawg.
Qhov tseem ceeb ntawm DC01 Steel
- Zoo heev Cold Formability- ua tsaug rau cov pa roj carbon tsawg thiab tswj tau cov alloying, DC01 tuaj yeem raug khoov, stamping, kos duab, thiab lwm yam txias - tsim cov txheej txheem uas muaj kev pheej hmoo ntawm kev tawg lossis tawg.
- Smooth nto tiav & Dimensional raug- txias dov ua kom nruj tuab tolerances thiab ib tug du nto, uas yog zoo tagnrho rau tom ntej txheej, painting los yog galvanizing.
- Zoo Weldability & Machinability- cov ntsiab lus tsis tshua muaj carbon zoo txhim kho weldability, thiab cov qauv microstructure txhawb kev ruaj khov vuam zoo thiab cov txheej txheem thib ob.
- Tus nqi -Nyob zoo & ntau yam- raws li lub hauv paus-qib txias- dov steel, DC01 feem ntau muaj thiab tus nqi pheej yig dua piv rau cov qib tshwj xeeb steel ntau dua.
Tej kev siv
Muab nws cov khoom siv kho tshuab / kho, DC01 steel yog dav siv hauv:
Automotive Cheebtsam:lub cev vaj huam sib luag, sab hauv vaj huam sib luag, tuav, kev txhawb nqa, thiab tsis yog - cov yam ntxwv tseem ceeb.
Cov khoom siv hauv tsev:vaj tse, vaj huam sib luag thiab cov khoom siv sab hauv rau lub tshuab ntxhua khaub ncaws, tub yees, qhov cub, cua-cua txias, thiab lwm yam.
General manufacturing:stamped los yog tsim qhov chaw, nyias- cov plhaub phab ntsa, chassis, brackets, enclosures, thiab lwm yam hlau tsim uas yuav tsum tau zoo formability thiab nto tiav.
Thaum raw khoom DC01 muaj qhov txwv tsis pub muaj kev tiv thaiv corrosion (ib txwm rau qis- carbon steels), nws yog qhov zoo rau kev kho deg xws li electro-galvanizing, pleev xim lossis txheej. Lub ntsej muag du thiab cov txheej txheem microstructure ntawm txias- dov DC01 tso cai rau cov adhesion zoo thiab kev faib tawm ntawm cov coatings - ua rau nws yog ib qho zoo substrate rau corrosion- tiv thaiv los yog cov ntaub ntawv zoo nkauj.
Peb lub tuam txhab tseem tuaj yeem muab cov khoom txias txias hauv qab no - dov steel qib:
