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!
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 los yog 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
