GNEE STEEL Ua tiav Kev Ua Haujlwm Siab -Kev Ua Haujlwm Q345qE Hlau rau Russia lub tshav dav hlau International Channel Hiav Txwv- Hla Choj
GNEE STEEL tau ua tiav thawj pawg ntawm kev hloov kho siab -kev ua tau zoo Q345qE steel rau cov khoom siv tseem ceeb ntawm cov dej hiav txwv channel- hla choj project ntawm Russia lub tshav dav hlau thoob ntiaj teb. Qhov kev txiav txim no yuav tsum tau kov yeej cov kev cai nruj nruj thiab cov nyom ntau lawm. Kev soj ntsuam kev tshaj lij tau lees paub tias cov hlau ua tau zoo tshaj qhov kev tsim qauv qauv, tshwj xeeb tshaj yog ua tau zoo nyob rau hauv qis- qhov kub thiab txias cuam tshuam qhov hnyav thiab tawm los- rau- tensile lub zog piv.
Raws li txoj hauv kev nkag mus rau lub tshav dav hlau, lub hiav txwv - hla tus choj imposes tshwj xeeb xav tau kev xav tau ntawm nws cov khoom siv. Cov xaiv Q345qE- qib choj steel phaj ua tau raws li ntau yam kev ua tau zoo:
- Transverse & longitudinal tensile zogua raws li cov qauv.
- Tsawg- kub cuam tshuam toughnessntawm -40℃ua tiav Ntau dua lossis sib npaug rau 120J hauv ob qho tib si transverse thiab longitudinal kev ntsuam xyuas.
- Yield -rau- tensile zog pivyog nruj me ntsis tswj kom tsawg dua los yog sib npaug rau 0.85 kom muaj kev nyab xeeb nyob rau hauv huab cua hnyav xws li cua daj cua dub thiab av qeeg.
Thaum tau txais qhov kev txiav txim, GNEE STEEL lub chaw ua haujlwm nrawm tau tsim ib tus ntoo khaub lig- pab pawg neeg qhuab qhia los daws cov teeb meem hauv kev lag luam, suav nrog kev ua kom zoo dua qub microstructure thiab qhov ua tau zoo ntawm cov phaj tuab. Qhov kev txhim kho no tau muab kev txhawb nqa tseem ceeb rau kev txhim kho qhov project.
Cov kev paub dhau los thiab cov ntaub ntawv tau txais los ntawm qhov siab -kev ua tau zoo Q345qE steel project ua haujlwm tseem ceeb tshwj xeeb rau yav tom ntej cov phiaj xwm loj hauv cov cheeb tsam hnyav, tshwj xeeb tshaj yog nyob rau thaj tsam txias thiab loj - txuas hniav. Tsiv mus tom ntej, GNEE STEEL yuav ntxiv dag zog rau kev tsim khoom thiab kev xa khoom kom muaj txiaj ntsig zoo rau cov khoom lag luam thiab cov kev pabcuam zoo tshaj rau cov neeg siv khoom.
Dab tsi yog steel Q345qE?
Q345qE raws li GB / T 714-2008 tus qauv yog tus choj steel qib. Raws li tus neeg xa khoom thiab xa tawm, peb tuaj yeem muab Q345qE kub dov daim hlau nrog tuab txog 100 hli. Txais tos tiv tauj peb email:alloy@gneesteelgroup.comYog tias koj txaus siab rau peb tus choj steel Q345qE phaj.
Q345qE yog ib qho qis- alloy siab- lub zog cov qauv hlau nrog lub zog tawm los ntawm 345 MPa thiab 400 MPa. Cov hlau no muaj qhov zoo tsawg- qhov kub thiab txias cuam tshuam qhov hnyav thiab, vim nws lub zog siab, lub teeb yuag, thiab kev ua haujlwm yooj yim, yog siv dav hauv ntau lub tsev, xws li txuas hniav, siab - cov tsev nce siab, thiab cov chaw tsim khoom.
Q345qE steel khoom
Q345qE steel muaj lub zog siab, toughness thiab tiv taus cov khoom thauj thiab cuam tshuam ntawm locomotives, thiab yuav tsum muaj kev qaug zog zoo, qee qhov kub tsis tshua muaj zog thiab atmoSPHEric corrosion kuj. Tsawg rhiab heev.

Kev siv ntawm Q345qE Steel Phaj
Q345qE steel choj phaj yog tshwj xeeb tuab steel phaj tsim rau kev tsim choj cov khoom siv. Nws yog tsim los siv cov pa roj carbon siab thiab qis- cov qib steel hlau rau kev tsim choj. Q345qE steel yog dav siv hauv kev tsim kho vim nws lub zog siab, zoo heev toughness, thiab corrosion kuj.
Cov ntawv thov tseem ceeb suav nrog:
- Kev tsim kho choj- dav siv nyob rau hauv lub ntsiab girders, choj decks, thiab txhawb cov qauv vim nws superior mechanical zog.
- High-cov tsev siab- Feem ntau ua hauj lwm ua thawj load-cov khoom siv hauv cov pob zeb ua vaj tse.
- Industrial cog kev tsim kho - ua haujlwm tseem ceeb rau cov qauv loj - txhawb nqa.
Cov khoom siv tshwj xeeb kev ua tau zoo ua rau nws zoo tagnrho rau cov phiaj xwm tseem ceeb uas xav tau kev ua haujlwm ntev thiab kev ntseeg tau raws li qhov xav tau.
GB / T 714 Q345qE choj steel phaj thiab ntawv xa tuaj rau hauv kub dov, tswj dov, normalized lossis normalized dov mob. Raws li tus neeg xa khoom ntawm Q345qE choj hlau, peb tuaj yeem muab cov kev pabcuam sib sib zog nqus xws li txiav, vuam, drilling, sib tsoo thiab kho cua sov.
