Kev sib piv: Txias- dov steel DC04 vs. DC01
Nrov specifications yog nyob rau hauv luv luv khoom!
nyem kom tau daim ntawv qhia tshwj xeeb!
DC01 steel yog dab tsi?
DC01 steel, los yog 1.0330, yog ib qho tsis yog - alloy zoo steel nrog tsawg carbon. Ua raws li cov ntawv tiaj tus los ntawm txias dov, nws muaj qhov du thiab zoo formability. Hom muaj xws li DC01-A, DC01-B, thiab electro-galvanized DC01+ZE (1.0330+ZE) raws li EN 10152. Cov qauv muaj feem xyuam yog EN 10130 thiab EN 10131. Variants DC03 txog DC07 muab kev tsim tau zoo dua. Nws yog siv rau cov khoom siv tsheb, cov khoom siv, thiab cov khoom siv hlau.
DC04 steel yog dab tsi?
DC04 yog qis- carbon, txias- dov sib sib zog nqus nqus hlau hauv DC- qib series ("Drawing Class" rau kev tsim cov ntawv thov). Muaj nrog kub -dip lossis electro-galvanized txheej raws li EN 10152-2017, nws muab kev tiv thaiv corrosion thiab zoo heev formability rau cov duab complex. Nrog rau cov khoom siv tus lej 1.0338, DC04 lub ntsej muag du yog qhov zoo tagnrho rau kev siv cov khoom siv hauv tsheb thiab khoom siv.
DC04 thiab DC01 yog ob qho tib si txias - dov, unalloyed zoo steels uas yog siv rau ntau yam kev siv. Thaum DC01 ua haujlwm raws li tus qauv qib rau cov txheej txheem txias txias, DC04 yog tus cwj pwm los ntawm kev txhim kho qhov sib sib zog nqus- kos duab thiab ntau dua ductility.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg cuam tshuam rau formability thiab weldability ntawm cov hlau. Ob leeg steels yog ua los ntawm carbon steel, tab sis DC04 muaj ib tug qis carbon cov ntsiab lus, uas txhawb nws cov kev txhim kho txias formability. Ua tsaug rau cov ntsiab lus qis carbon thiab sulfur, DC04 muaj kev txhim kho qhov sib sib zog nqus- kos peev xwm raws li qhov sib txawv intergranular embrittlement tshwm sim.
| Element | DC01 (max.%) | DC04 (max.%) |
|---|---|---|
| Cov pa roj carbon (C) | 0,12 | 0,08 |
| Manganese (Mn) | 0,60 | 0,40 |
| Phosphorus (P) | 0,045 | 0,030 |
| Sulfur (S) | 0,045 | 0,030 |
Mechanical zog
Cov khoom siv kho tshuab yog txiav txim siab rau kev tsim cov txheej txheem thiab tus cwj pwm ntawm cov hlau hauv qab load. DC04 muaj lub zog qis zog thiab elongation ntau dua, uas ua rau cov khoom siv yooj yim dua. Lub zog qis zog thiab nce qhov tsawg kawg nkaus elongation ntawm DC04 ua rau cov khoom siv no zoo tagnrho rau kev tsim cov txheej txheem xws li kev sib sib zog nqus nqus.
| Yam ntxwv | dc01 ua | dc04 ua |
|---|---|---|
| Yield zog (MPa) | Tsawg dua los yog sib npaug li 280 | Tsawg dua lossis sib npaug li 210 |
| Tensile zog (MPa) | 270-410 | 270-350 |
| Elongation (ntawm 80mm,%) | Ntau dua lossis sib npaug li 28 | Ntau dua lossis sib npaug li 38 |
Cov cheeb tsam ntawm daim ntawv thov
Ob leeg steels yog siv nyob rau hauv ntau ceg ntawm kev lag luam, tab sis lawv txawv nyob rau hauv cov nqe lus ntawm lawv optimum cheeb tsam ntawm daim ntawv thov:
dc01 ua
- Lub tsev thiab cladding qhov chaw
- Yooj yim tsim qhov chaw
- Cov khoom siv nrog cov qib qis ntawm deformation
dc04 ua
- Sib sib zog nqus- kos cov khoom nrog cov duab siab
- Tsheb lub cev qhov chaw
- Cov khoom siv hauv tsev nrog cov kev xav tau saum npoo siab
