Gnee Steel (Tianjin) Co., Ltd. yog ib qho ntawm cov kws tshaj lij q295gnh siab- tensile steel: huab cua resistant rau kev tsim kho manufacturers thiab lwm tus neeg nyob hauv Suav teb. Txais tos rau kev lag luam wholesale customized q295gnh siab- tensile steel: huab cua resistant rau kev tsim kho ntawm tus nqi sib tw los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab cov khoom zoo yog muaj.
Khoom Description
Q295GNH yog tus hwm zoo siab - tensile steel engineered rau cov qauv siv thov kom tshwj xeeb huab cua tiv thaiv thiab txhua yam kev ncaj ncees. Ua raws liGB/T 4171-2008thiabGB/T 1591-2008cov qauv, cov hlau no ua ke nrog kev tiv thaiv corrosion siab heev nrog kev ua haujlwm siab - muaj zog, ua rau nws zoo tagnrho rau cov txuas hniav, cov tsev siab - nce siab, thiab kev lag luam kev lag luam raug rau huab cua hnyav.
Advanced Material Science
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 nag, thaum tswj cov pa roj carbon (tsawg dua los yog sib npaug rau 0.12%) kom weldability thiab ductility.
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 26%, kom ntseeg tau tias muaj peev xwm thauj khoom hauv qab cua thiab seismic loads.
Kev cuam tshuam kev cuam tshuam: Ntau dua lossis sib npaug ntawm 34J ntawm -20℃(Qib D) rau Ntau dua lossis sib npaug rau 60J (xav tau rau cov ntawv thov tseem ceeb), tseem ceeb rau qhov qis - qhov kub thiab qhov siab-seismic zones.
Huab cua Resistance Mechanism
Tus kheej -Kho Oxide Txheej: Sij hawm dhau mus, raug cov dej noo thiab cov pa oxygen ua rau kev tsim ntawm a50-100μm tuab xeb patina, ua raws li lub ntuj barrier tiv thaiv chloride ingress nyob rau hauv cov ntug hiav txwv dej thiab sulfur dioxide nyob rau hauv nroog ib puag ncig. Qhov no txo cov nqi txij nkawm los ntawm50%piv rau pleev xim rau carbon steel.
Environmental Tolerance siab heev:
Tawm tsam1000-teev ntsev tsuag tshuaj ntsuam(5% NaCl tov ntawm 35 degree) nrog tsawg pitting.
Ua kom siab dua lossis sib npaug li 80% ntawm nws lub zog tawm los ntawm 600 degree, haum rau siab -kev siv kub xws li cov khoom siv hluav taws xob.
Txheem & Ua raws cai
Cov ntawv pov thawj: Ua raws liGB/T 4171-2008, TS EN 10025-5, thiab yeemASTM A588 Cov Lus Qhia Tshwj Xeeb(sib npaug rau S355J2G1W) rau cov haujlwm thoob ntiaj teb.
Quality Assurance: Txhua pawg tau kuaj xyuas ultrasonic, tshuaj xyuas tshuaj, thiab tshuaj ntsev tshuaj xyuas kom ntseeg tau tias muaj kev sib haum xeeb.
Economic & Environmental Benefits
Nqi Efficiency: Cov nqi kho mob qis dua (50% txo qis dua cov pa roj carbon monoxide) thiab txuas ntxiv lub neej kev pab cuam (25+ xyoo) offset ntau dua cov nqi pib, nrog rau lub sij hawm them rov qab feem ntau hauv 5-7 xyoo.
Sustainability: Txo cov khoom pov tseg thiab kev siv hluav taws xob, ua rau LEED-cov haujlwm tau lees paub txog li15% .
