4. Txawv txhais tau tias:
Rau S355J2H, "H" hauv S355J2H sawv cev rau seem hollow, qhia tias nws yog cov yeeb nkab steel nrog hollow cross-section.
"G3" nyob rau hauv S355J2G3 yog hais txog qhov tseeb hais tias nws yog normalized, qhia tias cov hlau tau raug tswj los ntawm kev kho cua sov txheej txheem los txhim kho nws cov khoom.
LEFIN STEELfeem ntau tsim cov kav dej nrog S355JRH, S355J0H thiab S355J2H cov qauv.
Cov khoom siv tshuaj ntawm S355J2G3:
C Tsawg dua lossis sib npaug rau 0.20
Si Less dua los yog sib npaug rau 0.55
Mn Tsawg dua lossis sib npaug rau 1.60
P Tsawg dua lossis sib npaug rau 0.035
S Tsawg dua lossis sib npaug rau 0.035
J2G3 txhais tau hais tias qhov kev xa khoom zoo li qub, lub zog cuam tshuam ntawm -20 degree yog 27J, thiab txoj kev deoxygenation yog G3.
Qhov zoo ntawm S355J2G3:
1.Lub zog muaj zog: S355J2G3 muaj lub zog tawm los ua haujlwm siab, ua rau nws tsim nyog rau cov haujlwm hnyav thiab qhov chaw muaj kev ntxhov siab.
2. Durability: Cov hlau no paub txog nws zoo heev tiv thaiv corrosion, huab cua, thiab puas, ua rau nws yog ib qho kev xaiv nrov rau cov qauv siv ntev thiab tshuab.
3. Versatility: S355J2G3 yog cov khoom siv tau yooj yim uas tuaj yeem siv ntau yam kev siv, los ntawm kev tsim kho thiab engineering mus rau kev tsim khoom thiab kev thauj mus los.
4.Tus nqi-zoo: Nws lub zog siab thiab ua haujlwm ntev ua rau nws muaj txiaj ntsig zoo rau kev xaiv rau cov ntawv thov uas lwm cov ntaub ntawv yuav xav tau kev saib xyuas ntau dua lossis hloov pauv.
5.Environmentally Friendly: Hlau yog cov khoom siv rov ua dua tshiab, ua S355J2G3 ib puag ncig lub luag haujlwm xaiv rau kev tsim kho thiab kev tsim khoom lag luam.
Daim ntawv thov ntawm S355J2G3:
1.Kev tsim kho kev lag luam. Nws yog feem ntau siv los tsim cov qauv xws li txuas hniav, vaj tse, thiab chaw ntau pob vim nws lub zog siab thiab muaj peev xwm ua tau zoo heev. Nws kuj tseem siv rau hauv kev tsim cov cranes, excavators, thiab lwm yam tshuab hnyav.
2. Kev lag luam tsheb thauj mus los kuj tseem siv S355J2G3 qib steel ntau heev. Nws yog siv los tsim cov khoom siv tsheb thiab cov khoom siv xws li chassis, axles, thiab ncua kev kawm ntawv. Lub zog thiab kav ntev ntawm cov hlau no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom uas raug kev nyuaj siab thiab hnav.
3. S355J2G3 qib steel yog siv nyob rau hauv kev tsim cov qauv offshore thiab cov kav dej. Nws lub zog siab thiab kev tiv thaiv corrosion ua rau nws yog ib qho khoom siv zoo tshaj plaws rau qhov hnyav marine ib puag ncig.
Zuag qhia tag nrho, S355J2G3 GRADE yog qib steel tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam. Nws lub zog thiab durability ua rau nws yog ib qho kev xaiv zoo rau ntau yam kev siv thiab kev ua haujlwm, kom ntseeg tau tias lawv tau tsim kom ntev.
