Q295GNH Huab cua Resistant Steel Rau Tsev & Kev Tsim Kho

Gnee Steel (Tianjin) Co., Ltd. yog ib qho ntawm cov kws tshaj lij q295gnh huab cua resistant steel rau lub tsev & kev tsim kho manufacturers thiab lwm tus neeg nyob hauv Suav teb. Txais tos rau kev lag luam wholesale customized q295gnh huab cua resistant steel rau lub tsev & kev tsim kho ntawm tus nqi sib tw los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab cov khoom zoo yog muaj.

Q295GNH yog huab cua zoo tshaj -cov qauv hlau resistant engineered rau kev thov architectural thiab kev tsim kho daim ntawv thov, adhering rauGB/T 4171-2008tus qauv. Cov hlau no ua ke nrog lub zog tensile siab, tus kheej - kho corrosion kuj, thiab tsim kom ruaj khov, ua rau nws zoo tagnrho rau cov choj, nroog infrastructure, ntug hiav txwv dej, thiab cov vaj tsev facades raug mob hnyav.

Core Engineering Properties

Alloy Composition: Muaj Cu (0.25-0.45%), Cr (0.30-0.65%), thiab Ni (0.25-0.50%), ua kom tuab-FeOOHoxide txheej uas txo cov nqi corrosion los ntawm2-8 lub sijhawmpiv rau cov pa roj carbon steel. Phosphorus (0.07-0.12%) txhim khu kev tiv thaiv rau acidic ib puag ncig, thaum tswj cov pa roj carbon (tsawg dua los yog sib npaug rau 0.12%) ua kom weldability thiab ductility.

Mechanical Performance:

Yield zog Ntau tshaj los yog sib npaug rau 295 MPa (thickness Tsawg dua los yog sib npaug rau 16mm), tensile zog 430-560 MPa, thiab elongation Ntau dua los yog sib npaug li 24%, kom ntseeg tau tias muaj peev xwm thauj khoom nyob rau hauv dynamic cua thiab seismic loads.

Kev cuam tshuam kev cuam tshuam: Ntau dua lossis sib npaug ntawm 34J ntawm -20℃(Qib A) rau ntau dua lossis sib npaug ntawm 27J ntawm -40℃(Qib E), tseem ceeb rau thaj chaw qis thiab siab seismic.

Huab cua & Corrosion Resistance

Kev tiv thaiv huab cua: Tsim kom muaj tus kheej- tiv thaiv xeb patina (50-100μm tuab) los ntawm kev raug dej noo thiab oxygen, uas ua rau lub cev tiv thaiv chloride ingress nyob rau hauv cov ntug dej hiav txwv thiab sulfur dioxide nyob rau hauv cov cheeb tsam muaj. Corrosion tus nqi tseem tsawg dua lossis sib npaug li 0.1 mm / xyoo hauv 5% NaCl ib puag ncig.

UV & Acid Resistance: Resistant UV aging perISO 4892-3thiab sulfuric acid ib puag ncig (70℃50% H₂SO₄) nrog tus nqi corrosion Tsawg dua lossis sib npaug li 14 mg / cm²·h, haum rau hauv nroog thiab thaj chaw muaj kev lag luam.

Fatigue Endurance: Optimized rau cyclic loading nrog qaug zog zog mus txogFAT80-FAT90(Eurocode 3), kom ntseeg tau tias lub neej ntev nyob rau hauv siab - cov ntawv thov kev vibration xws li cov kav xa hluav taws xob.

Ntau hom kev siv hauv kev tsim kho

• Architectural Structures:

Facades & Cladding: Siv nyob rau hauv cov nag npo tshuab thiab cov vaj huam sib luag zoo nkauj rau nws lub ntuj xeb patina thiab UV tsis kam, raws li pom hauv Swiss Landscape Park's folded steel flooring thiab Seoul West Lake Park's geometric planters .

Ru tsev & Canopies: Resistant dej nkag mus thiab thermal expansion nyob rau hauv lub ntug dej hiav txwv cheeb tsam, txo nqi txij nkawm los ntawm50%piv rau pleev xim rau carbon steel.

• Infrastructure:

Choj & Overpasses: Ua kom muaj kev cuam tshuam siab rau kev tsheb ciav hlau viaducts thiab txoj kev loj guardrails hauv chloride - nplua nuj ib puag ncig .

Cov tuam tsev muaj: Qhov zoo tshaj plaws rau cov khoom siv tshuaj khib nyiab thiab cov khoom siv mining vim nws tsis kam mus rau abrasive thiab corrosive tej yam kev mob.

Sustainable Design:

Kev tsim kho Modular: Yooj yim tsim rau hauv cov geometries nyuaj (piv txwv li, nkhaus kab) nrog bending radii tsawg li d=a rau thicknesses tsawg dua los yog sib npaug li 6 hli, txhawb prefabrication thiab ceev sib dhos.

• Sustainable Design:

Kev tsim kho Modular: Yooj yim tsim rau hauv cov geometries complex (xws li, nkhaus kab) nrog khoov radii tsawg li d=a rau thicknesses tsawg dua los yog sib npaug rau 6 hli, txhawb prefabrication thiab ceev sib dhos
