Galvanized Steel yog dab tsi?
Galvanized steel hais txog carbon steel coated nrog ib txheej tiv thaiv ntawm zinc los tiv thaiv corrosion. Cov zinc txheej tiv thaiv lub hauv paus hlau los ntawm ya raws, oxygen, thiab cov pa phem, cuam tshuam rau lub neej kev pab cuam ntawm cov khoom.
Galvanization feem ntau yog ua tiav los ntawm cov txheej txheem kub -dip, qhov twg hlau yog immersed nyob rau hauv molten zinc ntawm kwv yees li 450℃. Qhov no tsim cov hlau nplaum sib txuas ntawm zinc thiab hlau, tsim ntau yam - txheej txheej tiv thaiv uas muaj kev tiv thaiv lub cev thiab electrochemical. Thaum muaj kev puas tsuaj saum npoo, zinc yuav sacrificially corrode ua ntej cov hlau, khaws cov kev ncaj ncees ntawm cov qauv.
Piv nrog rau cov hlau txias txias, galvanized steel ua kom pom qhov zoo tshaj plaws tiv thaiv xeb, ua rau nws indispensable nyob rau hauv kev tsim kho, tsheb thauj mus los, industrial khoom, infrastructure, thiab cov neeg siv khoom.Ntawm ntau qib kev lag luam,DX51D + Z160 galvanized steel kaujyog tshwj xeeb tshaj yog muaj nuj nqis rau tej yaam num uas yuav tsum tau txhim kho corrosion kuj tsis muaj sacrificing formability los yog economic efficiency.
Kev nkag siab zoo ntawm DX51D + Z160
DX51D yog qib kev ua txias txias tau teev tseg hauv EN 10346, muab cov neeg kho tshuab zoo sib xws thiab qhov zoo. Nws yog tsim rau dabtsi yog khoov, yob txoj kev, stamping, thiab sib sib zog nqus daim duab.
Lub npeZ160qhia txog zinc txheej loj ntawm 160 g / m² ntawm ob sab ntawm cov hlau sawb, xa cov kev tiv thaiv corrosion ntau dua li cov txheej txheem xws li Z100 lossis Z120.
Tshuaj muaj pes tsawg leeg ntawm DX51D Steel
| Element | C (max) | Mn (max) | P (max) | S (max) | Ti (max) |

| % | 0.12 | 0.60 | 0.10 | 0.045 | 0.30 |
Mechanical Properties ntawm DX51D
| Khoom | Tus nqi |
|---|---|
| Yield zog | Ntau tshaj lossis sib npaug li 140 MPa |
| Tensile zog | 270-500 MPa |
| Elongation A80 | Ntau dua lossis sib npaug li 22% |
| Formability | Zoo heev |
| Weldability | Zoo heev |
Qhov kev sib npaug ntawm cov tshuab ua kom ntseeg tau tias DX51D + Z160 ua tau zoo hauv ob qho tib si kev ua haujlwm thiab kev zoo nkauj.
Qhov zoo ntawm Z160 Zinc Txheej
Z160 txheej muab cov txheej zinc tuab dua piv nrog cov txheej txheem lag luam txheej txheem, txhim kho lub sijhawm ntev - corrosion kuj nyob rau sab nraum zoov thiab ib nrab - kev lag luam ib puag ncig.
Cov txiaj ntsig tseem ceeb suav nrog:
- Lub neej ua haujlwm ntev dua hauv cov huab cua ntub thiab ntug hiav txwv
- Txo cov kev tu ncua
- Kev tiv thaiv zoo dua rau kev puas tsuaj thaum tsim thiab kev teeb tsa
- Ua siab ntev rau kev puas tsuaj rau txhua yam thaum thauj
Cov kev pab cuam lub neej nyob rau sab nraum zoov raug ntau tshaj15-20 xyoonyob rau hauv ib txwm tej yam kev mob.
