Kev txiav txim siab ntawm Corten A thiab Corten B? Peb sib piv lawv lub zog tawm los (345 MPa vs . 295 MPa), kev tiv thaiv corrosion, thiab tsim nyog rau cov choj vs. architectural facades los pab koj xaiv txoj cai.
Thaum qhia txog huab cua steel rau kev thauj khoom-cov qauv kabmob- xws li cov txuas hniav, cov thawv ntim khoom, lossis cov pob txha muaj pob txha-Corten AthiabCorten Byog ob qib tseem ceeb. Ob leeg yog qis- alloy, siab - lub zog steels uas tsim ib txheej tuab, ruaj khov xeb, kav ntev dua li cov pa roj carbon ntau. Txawm li cas los xij, qhov sib txawv me me hauv cov tshuaj muaj pes tsawg leeg ua rau muaj qhov tsis sib xws hauv kev ua haujlwm txhua yam. Cov lus qhia no tawgnqes cov ntsiab lus tseem ceeb los pab koj xaiv qib zoo rau koj qhov project.
Mechanical Strength: Qhov Kev Txiav Txim Siab
Thaum building hnyav -load qauv, mechanical kev ua tau zoo yog thawj metric.
- Corten B (Lub Hnyav Lifter):Los ntawm cov qauv kev lag luam, Corten B yog qhov kev xaiv muaj zog dua. Rau ntu txog li 100 hli tuab, nws muaj aTawm zog ntawm 345 MPathiab aTensile zog ntawm 485 MPa. Qhov tseem ceeb, Corten B tuav lub zog zoo dua thaum huab cua txias. Nws tiv taus brittleness txawm nyob ntawm0 degree, ua kom muaj kev nyab xeeb rau tej yaam num hauv cheeb tsam khov.
- Corten A (Qhov Kev Xaiv Zoo Nkauj):Corten A muab qis dua me ntsisTawm zog ntawm 295 MPathiab Tensile zog ntawm 480 MPa. Thaumtxaus rau facades, feem ntau nws tsis yog thawj qhov kev xaiv rau hnyav hnyav -load skeletons.
Kev sib piv Corrosion Resistance
Yog koj qhov projectt nyob ze ntawm ntug dej hiav txwv lossis thaj chaw muaj kev lag luam, kev tiv thaiv corrosion tsis yog -negotiable.
- Corten A:Muaj phosphorus ntau dua, muab nws ib qho me ntsis ntug. Nws tiv taus atmospheric corrosion5 rau 8x zootshaj carbon steel.
- Corten B:Tseem impressive, muab txog4x uaqhov tsis kam ntawm carbon steel.
Qhov Kev Txiav Txim:Ob qib tsim cov txheej txheem tiv thaiv xeb hauv 1-2 xyoos, tshem tawm qhov xav tau kev pleev xim. Txawm li cas los xij, rau corrosive heevib puag ncig (xws li cov nroj tsuag tshuaj los yog thaj chaw ntug dej hiav txwv),Corten Ayog qhov kev xaiv zoo dua.
Daim ntawv thov Scenario
1. Hnyav-Duty Cov Qauv: Xaiv Corten B
Vim nws lub zog tensile siab thiab cuam tshuam tsis kam, Corten B yog qhov mus - xaiv rau:
- Shipping Thawv:80% ntawm cov thawv siv Corten B los tiv thaiv kev thauj mus los ntau dua.
- Infrastructure:Railway txuas hniav, kev txhawb nqa kev loj, thiab chaw nres nkoj cia platforms.
- Complex Assemblies:Nws zoo heev weldability ua rau nws zoo tagnrho rau ntawm - site fabrication ntawm loj thav duab.
2. Nruab nrab-Load & Aesthetic Structures:
Xaiv Corten ACorten A yog qhov zoo tshaj plaws uas qhov tseem ceeb ntawm kev tiv thaiv corrosion tshaj qhov hnyav hnyav -cov kev xav tau ntawm cov kabmob:
- Architectural Facades:Kho kom zoo nkauj cladding thiab sab nraum zoov pej thuam.
- Lub teeb ru tsev:Factory roofs thiab photovoltaic support thav ntawv.
- Kev nyab xeeb me me:Tus nqi - kev xaiv zoo rau cov tsev khaws khoom nyob deb nroog qhov twg qis - qhov kub thiab txias tsis yog qhov tseem ceeb.
Nqi vs. Lifecycle Value
Corten B yog kojpically kim dua vim nws cov hlau alloy ntau dua thiab cov khoom siv zoo. Txawm li cas los xij, cov neeg yuav khoom ntse saib covTus nqi Lifecycle. Rau siab - cov haujlwm thauj khoom, Corten B lub zog tso cai rau cov seem thinner (txo tag nrho cov khoom tonnage) thiab txo cov txij nkawm ntawmqauv lub neej. Tus nqi them thawj zaug them tawm hauv lub sijhawm ntev - kev nyab xeeb thiab kav ntev.
Daim Ntawv Xeem Kawg
Los xaus, uua raws li 4 yam no los txiav txim:
- Thauj khoom:Siab load=Corten B; Nruab nrab load=Corten A.
- Ib puag ncig:Coastal/High Corrosion=Corten A nyiam dua.
- Kub:Cov cheeb tsam khov=Corten B (rau toughness).
- Nyiaj txiag:Xav txog kev txuag lub neej, tsis yog tus nqi them ua ntej xwb.
Ib txwm request ibMaterial Test Certificate (MTC)txhawm rau txheeb xyuas qib (xws li ASTM A588) ua ntej yuav khoom.
Tseem tsis paub meej tias Qib twg haum koj daim ntawv qhia?
Koj tsis tas yuav yogtus kws tshaj lij steel los ua qhov kev xaiv zoo. Promisteel's engineers tuaj yeem tshuaj xyuas koj qhov kev xav tau ntawm qhov project thiab pom zoo rau qib zoo meej, txawm tias nws yogCorten Arau facades los yogCorten Brau structural beams.
