1.5mm Q550NH hlauua ke ib daim ntawv nyias -gauge steel nrog lub zog siab thiab atmospheric corrosion kuj ntawm GB/T 4171 Q550NH weathering steel.
Rau cov thawv ntim khoom thiab cov khoom siv thauj khoom tsim tawm, nyias Q550NH tuaj yeem txiav txim siab qhov twg qhov hnyav txo, kev sib sau tas mus li, kev tiv thaiv corrosion thiab lub zog ntawm cov qauv ua ke.
Ntawm 1.5 hli thickness, Q550NH ntog nyob rau hauv qhov tsawg tshaj li los yog sib npaug rau 16 hli mechanical- khoom vaj tse ntau yam ntawm GB/T 4171. Qhov tsawg kawg nkaus yield zog yog 550 MPa, tensile zog yog 620-780 MPa, thiab yam tsawg kawg nkaus elongation yog 16%.
Vim li cas Siv 1.5mm Q550NH Hlau rau Cov Thawv Hnav?
Lub thawv ntim khoom xav tau qhov sib npaug ntawm cov hlau thickness, lub zog, corrosion kuj, tsim muaj peev xwm thiab tiav qhov hnyav. Pas huab cua steel thawv sab vaj huam sib luag feem ntau pom nyob ib ncig ntawm 1.6 hli, thaum 2.0 hli cov khoom siv kuj yog nyob ntawm lub vaj huam sib luag txoj hauj lwm thiab cov qauv tsim.
Siv 1.5mm Q550NH weathering steel tuaj yeem txo cov hlau hnyav ntawm ib cheeb tsam ib cheeb tsam thaum tswj cov qib siab nominal zog ntawm Q550NH. Txawm li cas los xij, kev txo thickness tsis tuaj yeem txiav txim siab los ntawm kev tawm dag zog ib leeg. Corrugation profile, vaj huam sib luag ncua, vuam tsim, qaug zog, cuam tshuam tsis kam thiab siv cov qauv ntim yuav tsum tau kuaj xyuas.
Nyhav Advantage ntawm 1.5mm Q550NH Steel Sheet
Siv ib tug raug steel ntom ntawm kwv yees li 7,850 kg / m³, theoretical loj ntawm 1.5 hli Q550NH steel ntawv yog kwv yees li 11.78 kg / m².
| Thickness | Theoretical Nyhav | Qhov txawv vs . 2.0 mm |
|---|---|---|
| 1.5 hli | 11.78 kg/m² | −25% |
| 1.6mm ib | 12.56 kg/m² | −20% |
| 2.0mm ib | 15.70 kg/m² | Kev siv |
Rau tib thaj chaw saum npoo, hloov ntawm 2.0 hli mus rau 1.5 hli steel txo cov theoretical raw-cov ntawv loj los ntawm kwv yees li 25%. Piv nrog 1.6 hli steel, qhov txo qis yog kwv yees li 6.25%.
Cov duab no tsuas yog piav txog cov khoom loj. Lawv tsis tau txhais hais tias lub vaj huam sib luag 1.5 hli tuaj yeem hloov ncaj qha rau 1.6 hli lossis 2.0 hli lub thawv vaj huam sib luag yam tsis muaj kev txheeb xyuas cov qauv.
1.5mm Q550NH Hlau Mechanical Properties
Vim tias 1.5 hli nyob rau hauv t Tsawg dua los yog sib npaug rau 16 hli thickness ntau, cov txheej txheem sib xws - khoom yuav tsum muaj rau Q550NH yog:
| Khoom | 1.5mm Q550NH yuav tsum tau |
|---|---|
| Thickness | 1.5 hli |
| Yam tsawg kawg nkaus Yield Strength | Ntau dua lossis sib npaug li 550 MPa |
| Tensile zog | 620-780 MPa |

| Txuj | GB/T 4171 |
| Yam khoom | Kub Rolled |
Kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob siab thiab cov ntsuas nyias nyias yog ib qho laj thawj Q550NH hlau tuaj yeem raug soj ntsuam rau cov qauv tsim cov khoom sib sib zog nqus uas cov pa qis dua - cov khoom siv zog yuav xav tau ntau dua thickness.
Tshuaj muaj pes tsawg leeg ntawm Q550NH Weathering Steel
Q550NH tsis yog ib qho siab - lub zog carbon steel. Cu, Cr thiab Ni muaj nyob rau hauv cov hlau tsim los txhim kho atmospheric corrosion kuj.
| Element | GB/T 4171 Q550NH (%) |
|---|---|
| C | Tsawg dua lossis sib npaug li 0.16 |
| Si | Tsawg dua lossis sib npaug li 0.65 |
| Mn | Tsawg dua lossis sib npaug li 2.00 |
| P | Tsawg dua lossis sib npaug li 0.025 |
| S | Tsawg dua lossis sib npaug li 0.030 |
| Cu | 0.20–0.55 |
| Cr | 0.30–1.25 |
| Ni | 0.12–0.65 |
GB / T 4171 kuj tso cai tswj kev ntxiv ntawm Nb, V thiab Ti rau kev hloov kho vaj tse. Qhov sib xyaw ua ke Nb + V + Ti ntxiv yuav tsum tsis pub tshaj 0.22%.
Qhov twg 1.5mm Q550NH hlau siv nyob rau hauv thawv Fabrication?
Rau lub teeb yuag tej yaam num, 1.5mm Q550NH steel yog tsim nyog los piav raws li ib yam khoom rau engineered nyias -gauge Cheebtsam es tsis xav tias nws muaj peev xwm hloov txhua tus qauv thawv steel tivthaiv.
Cov ntawv thov muaj peev xwm suav nrog cov khoom siv sab hauv phab ntsa corrugated, lub teeb yuag vaj huam sib luag, thawv -cov khoom siv ntsig txog vaj tsev, cov khoom siv thauj mus los thiab lwm yam huab cua tsim- cov khoom tiv thaiv.
Rau kev siv, kev lag luam thawv sab- cov khoom siv phab ntsa feem ntau siv kwv yees li 1.6 hli weathering steel, thiab cov corrugated profiles yog siv los muab cov vaj huam sib luag nruj. Yog li ntawd, lub tswv yim 1.5 hli Q550NH tsim yuav tsum tau soj ntsuam ua ke nrog corrugation geometry es tsis muab piv tiaj tus - ntawv thickness ib leeg.
Vim li cas daim ntawv thiaj li tsim nyog rau ntim khoom
Rau siab - ntim ntim fabrication, Q550NH steel muaj ib qho tseem ceeb ua kom zoo dua tus kheej muab cov hlau phaj.
Cov hlau tuaj yeem decoiled thiab leveled ua ntej nkag mus txuas ntxiv txiav lossis yob - cov cuab yeej tsim. Cov neeg tsim khoom tuaj yeem tsim rov ua vaj huam sib luag qhov ntev thiab corrugation profiles nrog tsawg cuam tshuam ntawm cov nplooj ntawv ib leeg.
Vim li no, nyias Q550NH weathering steel yog tshwj xeeb tshaj yog muaj feem xyuam rau cov tuam txhab uas xav tau siab - ntim daim ntawv es tsis hnyav ib tug structural phaj.
Ua 1.5mm Q550NH Steel
Ib txoj kev ua haujlwm raug pib nrog decoiling thiab leveling. Cov khoom siv tuaj yeem raug txiav mus rau qhov xav tau dav lossis txiav rau daim ntawv ntev. Nyob ntawm qhov kawg ntawm cov qauv tsim, cov txheej txheem tom ntej tuaj yeem suav nrog yob txoj kev, corrugation forming, dabtsi yog khoov, xuas nrig ntaus, laser txiav thiab vuam.
Rau 1.5mm Q550NH steel ntawv, qhov tseeb qhov tseeb thiab flatness ua qhov tseem ceeb tshwj xeeb vim tias cov khoom nyias nyias muaj kev cuam tshuam ntau dua rau kev sib txawv thaum lub sij hawm sib sau, sib sau thiab vuam.
Vuam tsis tseem yuav tsum tau xaiv raws li qhov tseeb sib koom tsim, cov khoom siv hluav taws xob thiab cov khoom tiav tiav es tsis xav tias tib txoj kev siv rau cov phaj tuab Q550NH tuaj yeem siv ncaj qha.
1.5mm Q550NH vs. Conventional Container Weathering Steel
Ntau lub thawv ntim khoom lag luam siv cov qib huab cua xws li SPA-H / Corten- hom hlau, nrog 1.6 hli ua ib sab sib xws- vaj huam sib luag thickness hauv cov khoom tam sim no.
| Kev sib piv | 1.5 hli Q550NH | 1.6mm Weathering Vaj Huam Sib Luag |
|---|---|---|
| Thickness | 1.5 hli | Nyob ib ncig ntawm 1.6 mm |
| Q550NH Yield zog | Ntau dua lossis sib npaug li 550 MPa | Nyob ntawm qib xaiv |
| Pawg | 11.78 kg/m² | 12.56 kg/m² |
| Qhov txawv | Kwv yees li 6.25% qis dua | Kev siv |
| Main Advantage | Siab zog + nyias gauge | Tsim cov thawv vaj huam sib luag specification |
| Kev Tshawb Fawb Engineering | Yuav tsum tau | Yuav tsum tau raws li lub thawv tsim |
Tus nqi ntawm Q550NH yog li tsis tsuas yog tias nws yog "0.1 hli thinner." Cov lus nug tseem ceeb dua yog seb nws qhov 550 MPa lub zog thiab cov huab cua huab cua puas tuaj yeem txhawb nqa lub teeb pom kev zoo dua qub thaum tseem ua tau raws li cov qauv, tsim, vuam thiab kev pabcuam.
Yuav Ua Li Cas Cov Neeg Yuav Tsum Qhia rau 1.5mm Q550NH Steel?
Thaum thov cov lus hais, tus neeg yuav khoom yuav tsum paub meej tias tsis yog 1.5 hli Q550NH hlau, tab sis kuj tseem yuav tsum tau steel dav, tag nrho cov khoom, ib qho - steel hnyav, steel puab txoj kab uas hla, ntug mob, nto yuav tsum tau thiab downstream ua.
Yog tias cov hlau yuav raug siv rau cov thawv ntim khoom, qhov kawg vaj huam sib luag qhov ntev, corrugation profile, txoj kev tsim, vuam yuav tsum tau thiab siv cov thawv tshwj xeeb yuav tsum tau muab rau kev tshuaj xyuas.
