galvanized hlau
DX51D galvanized hlauyog ib qho ntawm cov siv dav tshaj plaws kub-dip galvanized steels hauv ntiaj teb cov qauv siv thiab vaj huam sib luag. Raws li European tus qauvTS EN 10346, qib DX51D txhais tau tias qis- carbon txias- ua cov hlau substrate uas, thaum coated nrog zinc ntawm kub-dip galvanizing, xa cov qib siab ntawm corrosion kuj thiab zoo heev formability rau ntau yam kev lag luam siv.
DX51D txhais li cas hauv Cov Qauv
| Code | Lub ntsiab lus |
|---|---|
| D | Txias- ua hlau haum rau galvanizing |
| X51 | Qib kev ua tau zoo nrog kev sib npaug zoo ntawm cov khoom siv kho tshuab |
| +Z | Kub-dip galvanized zinc txheej ntxiv |
Qhov kev xaiv no qhia tau hais tias DX51D galvanized steel yog optimized rau dabtsi yog khoov, vuam, xuas nrig ntaus thiab sib sib zog nqus kos duab thaum muaj txiaj ntsig los ntawm kev tiv thaiv corrosion txuas ntxiv.
Chemical Composition ntawm Base Steel
| Lub ntsiab | Cov ntsiab lus siab tshaj (%) |
|---|---|
| C | Tsawg dua lossis sib npaug li 0.12 |
| Mn | Tsawg dua lossis sib npaug li 0.60 |
| P | Tsawg dua lossis sib npaug li 0.10 |
| S | Tsawg dua lossis sib npaug li 0.045 |
| Si | Tsawg dua los yog sib npaug li 0.50 |
Xws li muaj pes tsawg leeg ua kom zoo ductility, weldability thiab zoo ib yam nto zoo ua ntej galvanizing.
Yam khoom siv cuab yeej cuab tam Range (EN10346)
| Khoom | Tus nqi |
|---|---|
| Yield zog (Rp0.2) | Ntau tshaj lossis sib npaug li 140 MPa |
| Tensile zog | 270-500 MPa |
| Elongation (A80) | Ntau dua lossis sib npaug li 22% |
| Hardness (HB) | 70–120 HB |
DX51D steel ua kom pom qhov sib npaug ntawm lub zog thiab elasticity haum rau kev sib sib zog nqus thiab tsim cov txheej txheem.
Txheej thiab tiv thaiv corrosion
| Txheej Code | Zinc Mass (g / m² ob sab) | Kwv yees li. Thickness (hli) |
|---|---|---|
| Z60 | 60 | ~9 |
| Z100 | 100 | ~14 |
| Z140 | 140 | ~20 |
| Z180 | 180 | ~26 |
| Z275 | 275 | ~40 |
Cov txheej txheem ntau dua ua rau muaj kev tiv thaiv atmospheric corrosion nyob rau hauv ib puag ncig hnyav.
