Cov khoom lag luam
S235JR yog qhov qis-} carbon, tsis - almoy txheej txheem steel txhais los ntawm EN 10025-2 txuj.
Cov "S" sawv ntsug rau "qauv," lub ntsiab lus nws yog rau siv nyob rau hauv thauj khoom {{cov kabmob seem ntawm cov tuam tsev, tshuab, lossis cov khoom siv hluav taws xob.
Tus naj npawb "235" yog hais txog nws li tsawg kawg zog zog {}} mategapualals-} Nws tuaj yeem tiv thaiv ua ntej deforming. Qib no ntawm lub zog yog tsim nyog rau ntau qhov dav ntawm {{4} lub hom phiaj kev thov uas tsis muaj kev ua tau zoo. Piv txwv li, nws muaj zog txaus rau txhua lossis kab teeb hauv cov tuam txhab txheem, tab sis tsis yog rau auryscrapers uas xav tau qib siab.
Lub "Jr" sawv ntsug rau "Joules" thiab "chav sov," qhia txog qhov kev cuam tshuam charpy Qhov kev ntsuas no ntsuas seb cov khoom siv tuaj yeem tawm tsam sai sai lossis kev cuam tshuam uas tsis muaj kev cuam tshuam nrog cov qauv uas tsis muaj kev cuam tshuam dab tsi, uas tsis muaj zog- zoo li cua lossis txav tsheb.
Ib qho ntawm cov tswv yim zoo ntawm S235JR yog nws qhov zoo weldability. Ua tsaug rau nws cov ntsiab lus carbon qis, nws tuaj yeem welded yooj yim thiab nyab xeeb siv cov txheej txheem qauv qauv, tsis muaj kev pheej hmoo ntawm cov qauv. Qhov no ua rau nws zoo tagnrho rau kev tsim kho ua haujlwm, uas ntseeg tau cov pob qij txha uas ntseeg tau.
Hais txog chemistry, s235jr muaj cov nyiaj me me ntawm manganese thiab silicon, uas pab txhim kho nws cov tshuab ruaj khov thiab kev coj cwj pwm. Txawm li cas los xij, nws tsis suav nrog corrosion - Resive elemic lossis npib chromium lossis npib tsib xee. Raws li qhov tshwm sim, nws tsis yog kev tiv taus xeb kom xeb thiab xav tau coated lossis pleev xim rau sab nraum zoov lossis siv cov chaw nyob sab nraud.

Cov Khoom Siv
S235JR yog cov qauv siv cov qauv siv ib txwm siv hauv Tebchaws Europe, paub txog nws lub zog zoo, wardability, thiab yooj yim ntawm kev ua. Nws yog siv ntau yam kev lag luam, tshwj xeeb tshaj yog qhov twg muaj cov muaj zog thiab lub zog siv tau ntawm tus nqi tsim nyog.
Hauv kev tsim kho, S235JR yog siv rau kev ua kab kab teeb, kab, thiab cov qauv txheej txheem hauv cov vaj tse thiab txuas hniav. Nws cov khoom siv ua kom nws txhim khu kev qha rau kev txhawb nqa khoom, thaum nws weldability tso cai rau kev sib dhos yooj yim ntawm- chaw. Nws kuj yog siv rau cov haujlwm ua haujlwm hauv zej zog xws li ntau yam, tuav phab ntsa, thiab cov qauv txhawb nqa.
Hauv kev siv tshuab, cov hlau yog siv rau cov ntu xws li nkhaus, txhawb nqa, thiab cov thav ntawv uas tsis xav tau siab {} lub zog alloys. Nws lub tshuab ua rau nws xaiv tau zoo rau kev tsim cov khoom siv nrog qhov ntev zoo, tshwj xeeb tshaj yog nyob rau hauv nruab nrab thiab khoom siv.
235JR tseem pom tau siv hauv kev lag luam hauv tsheb thiab thauj khoom, qhov twg nws tau siv rau chassis qhov chaw, cov ntawv trailer, thiab lwm yam txheej txheem txheej txheem. Thaum tsis haum rau siab - kev tsim tsheb, nws muaj qhov kev xaiv muaj zog thiab pheej yig rau kev siv dav dav.
Nws cov kev txwv tseem ceeb yog cov tshuaj tiv thaiv corrosion tsawg. Vim li no, nws tsis zoo rau cov tub rog ib puag ncig lossis cov xwm txheej nrog cov dej noo siab tshwj tsis yog coated lossis pleev xim. Txawm li cas los xij, nyob rau hauv feem ntau cov kev mob, nws ua tau ntseeg tau thiab yog ib qho ntawm feem ntau dav steels hauv Tebchaws Europe.
