S320GD Steel Qib
S320GD yog cov qauv-qib steel tshwj xeeb tsim los rau cov ntawv thov kub dip galvanizing. Nws yog dav lees paub rau nws qhov sib npaug ntawm cov neeg kho tshuab lub zog, formability, thiab nto txheej compatibility.
Lub npe S320GD tuaj yeem txhais raws li hauv qab no:
- S: Cov qauv hlau
- 320: Yam tsawg kawg nkaus tawm lub zog ntawm 320 MPa
- GD: Muab nyob rau hauv galvanized mob
Qib no feem ntau yog xaiv rau kev thauj khoom -cov kabmob uas muaj kev tiv thaiv corrosion thiab ntev ntev -lub sijhawm ntev yog qhov tseem ceeb sib npaug.
Piv nrog rau qib qis dua -lub zog galvanized qib, S320GD muab kev ua haujlwm zoo dua thaum tuav cov yam ntxwv zoo, ua rau nws tsim nyog rau ob qho tib si yob txoj kev thiab kev tsim khoom.
Dab tsi yog Kub Dip Galvanized Steel?
Kub dip galvanized steel yog tsim los ntawm immersing hlau rau hauv molten zinc ntawm qhov kub thiab txias. Thaum lub sijhawm txheej txheem no, daim ntawv cog lus metallurgical ntawm zinc thiab steel substrate, tsim ntau zinc{1}}hlau alloy txheej.
Txoj kev txheej txheej no muaj kev tiv thaiv zoo dua li kev pleev xim rau saum npoo los yog electro-galvanizing, tshwj xeeb tshaj yog nyob rau sab nraum zoov lossis chaw ua haujlwm.
Cov txiaj ntsig tseem ceeb ntawm kub dip galvanizing muaj xws li:
- Tag nrho - tiv thaiv corrosion
- Tus kheej- kho muaj peev xwm ntawm kev txiav ntug
- Lub neej ua haujlwm ntev nrog kev saib xyuas tsawg
- Uniform txheej thickness
Thaum siv rauS320GD qauv steel, kub dip galvanizing txhim kho ob qho tib si kev ua haujlwm thiab kev lag luam tus nqi.
Z275 yog hais txog tag nrho cov zinc txheej loj ntawm275 g/m², faib rau ob sab ntawm cov hlau nto. Qhov txheej txheej no yog dav siv rau kev tsim kho thiab kev lag luam siv vim nws qhov muaj zog sib npaug ntawm kev tiv thaiv thiab kev ua haujlwm zoo.
Zinc Txheej Kev Ua Haujlwm Sib Piv
| Zinc Txheej | Tag nrho cov txheej txheej (g / m²) | Hom Kev Pabcuam Lub Neej |
|---|---|---|
| Z100 | 100 | Luv - siv sab hauv tsev |
| Z180 | 180 | Teeb pom kev sab nraum zoov |
| Z275 | 275 | Kev tsim qauv & siv sab nraum zoov |
| Z350 | 350 | High humidity ib puag ncig |
Z275 feem ntau suav hais tias yog cov txheej txheem txheej txheem rau cov txheej txheem galvanized steel hauv kev lag luam thoob ntiaj teb.
Mechanical Properties ntawm S320GD + Z275
| Khoom | Tus nqi | Chav tsev |
|---|---|---|
| Yield zog | Ntau dua lossis sib npaug rau 320 | MPa |
| Tensile zog | 420–550 | MPa |
| Elongation (A80) | Ntau dua lossis sib npaug 22 | % |
| Zinc Txheej | Z275 | g/m² |
Cov yam ntxwv zoo li no tso caiS320GD kub dip galvanized steel kauj thiab ntawvua kom ntseeg tau nyob rau hauv txhua yam kev ntxhov siab thaum tswj xyuas corrosion zoo heev.
Tej kev siv
S320GD + Z275 kub dip galvanized steel feem ntau siv hauv:
- Cov txheej txheem framing
- vov tsev thiab phab ntsa cladding
- Purlins thiab txhawb nqa beams
- Industrial enclosures
- Kev ua liaj ua teb thiab chaw cia khoom
Nws versatility ua rau nws haum rau ob qho tib si qauv tsim thiab customized fabrication tej yaam num.
