Siab -Lub zog Q295GNH Corten Steel Rau Choj

Gnee Steel (Tianjin) Co., Ltd. yog ib qho ntawm cov kws tshaj lij siab tshaj -lub zog q295gnh corten steel rau choj tuam ntxhab thiab cov muag khoom hauv Suav teb. Txais tos rau kev lag luam wholesale customized siab -lub zog q295gnh corten steel rau txuas hniav ntawm tus nqi sib tw los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab cov khoom zoo yog muaj.

Q295GNH Corten Steel yog ib qho zoo tshaj plaws weathering steel engineered rau qhov tseem ceeb choj infrastructure, adhering rauGB/T 4171-2008tus qauv. Cov hlau no ua ke nrog lub zog tensile siab, tshwj xeeb corrosion kuj, thiab qaug zog endurance, ua rau nws zoo tagnrho rau ntev - ncua txuas hniav, railway crossings, thiab marine- cov qauv raug.

Core Engineering Properties

• Alloy Composition: Muaj Cu (0.25-0.45%), Cr (0.30-0.65%), thiab Ni (0.25-0.50%), tsim cov txheej txheem kho tus kheej (-FeOOH) uas txo cov nqi xeb los ntawm2-8 zaugpiv rau cov pa roj carbon steel.
• Mechanical Performance:

Yield zog Ntau dua los yog sib npaug rau 295 MPa (thickness Tsawg dua lossis sib npaug li 16mm), tensile lub zog 430-560 MPa, thiab elongation Ntau dua lossis sib npaug li 24%, kom ntseeg tau tias muaj peev xwm thauj khoom hauv cov tsheb thauj mus los.

Kev cuam tshuam kev cuam tshuam: Ntau dua lossis sib npaug rau 34J ntawm -20℃(Qib A) rau ntau dua lossis sib npaug rau 27J ntawm -40℃(Qib E), ua tau raws li qhov xav tau huab cua huab cua.

Fatigue & Corrosion Resistance

• Fatigue Endurance: Tsim los tiv thaiv kev thauj mus los nrog kev ntxhov siab ntau yam ua kom zoo rau cov pob qij txha welded (xws li, FAT80-FAT90 cov chav kawm qaug zog ib Eurocode 3). Qhov no ua rau nws tsim nyog rau cov tsheb thauj mus los loj uas qhov kev qaug zog tawg yog qhov kev txhawj xeeb tseem ceeb.
• Ntsej Tsuag Performance: Qhia tawm qhov corrosion tsawg tsawg nyob rau hauv kev sim ceev (xws li, 5% NaCl tov ib ASTM B117), nrog cov nqi corrosion tsawg dua los yog sib npaug li 0.1 hli / xyoo tom qab 1000 teev, ua tau zoo dua cov hlau tsis muaj hlau nyob hauv ntug dej hiav txwv lossis de- ib puag ncig iced.

Choj-Cov ntawv thov tshwj xeeb

• Ntev -Span Structures: Siv nyob rau hauv truss girders thiab box beams rau txuas hniav zoo li lubG107 Kab Xinyang Railway Overpass, qhov twg nws lub zog siab txo cov khoom siv los ntawm 15-20% piv rau Q345 steel.
• Railway Choj: Tiv thaiv kev puas tsuaj los ntawm kev tsheb ciav hlau thiab tshuaj tsuag ntsev, nrog rau cov ntawv thov hauv siab -ceev rail viaducts thiab freight rail crossings .
• Marine Environments: Zoo tagnrho rau cov ntug hiav txwv dej (piv txwv li,Qingdao Bay Choj) vim nws tsis kam chloride -induced corrosion .

Fabrication & Maintenance

• Vuam: Yuav tsum tau ua ntej- vuam tu ntawm 10-20mm nyob ib ncig ntawm cov pob qij txha los tiv thaiv corrosion ingress . Kev siv cov Cu-cov kabmob muab tub lim ua kom cov welds phim cov khoom siv huab cua tsis kam.
• Txias txoj kev: Yooj yim rau hauv cov duab geometries (piv txwv li, nkhaus girders) nrog bending radii tsawg li d=a rau thicknesses Tsawg dua los yog sib npaug li 6 hli .
• Kev tu: Tshem tawm qhov xav tau rau kev pleev xim tsis tu ncua, txo cov nqi ntawm lub neej los ntawm 50% tshaj 25+ xyoo.

Txheem & Ua raws cai

• Cov ntawv pov thawj: Ua raws liGB/T 4171-2008thiab xaiv tau EN 10025-5 rau cov haujlwm thoob ntiaj teb.
• Quality Assurance: Txhua batch tau kuaj ultrasonic thiab tshuaj ntsuam xyuas kom ntseeg tau tias muaj kev sib haum xeeb.

Environmental & Economic Benefits

• Sustainability: Rov ua dua tshiab thaum kawg - ntawm - lub neej thiab txo VOC emissions los ntawm kev tshem tawm cov xim pleev xim.
• Nqi Efficiency: Kev saib xyuas qis dua thiab kev pab lub neej ntev dua cov nqi pib dua, nrog rau lub sijhawm them rov qab feem ntau hauv 5-7 xyoo.
