Thaum xav txog S235J2W Corten steel rau cov qauv, nws qhov tseem ceeb lub zog qhov tseem ceeb yog thawj qhov chaw kuaj xyuas rau engineers. Cov lej no txiav txim siab seb nws puas tuaj yeem nqa cov khoom thauj uas tau npaj tseg.
Cov lus teb luv luv: Lub zog ua tau raws li cov qauv kev cia siab
Rau S235J2W Corten steel, qhov tsawg kawg nkaus tawm los thiab tensile zog yog tswj los ntawm European tus qauv EN 10025-5. Cov txiaj ntsig zoo ib yam rau lwm qib S235, tab sis tsab ntawv tseem ceeb hauv nws lub npe ua rau muaj qhov sib txawv loj rau qee yam kev siv.
Yam tsawg kawg nkaus tawm lub zog (ReH): 235 MPa
Qhov no yog qhov kev ntxhov siab uas cov hlau pib deform mus tas li. Nws yog qhov txwv tsis pub siv rau hauv cov qauv tsim los tiv thaiv kev ua tsis tiav. Lub "235" nyob rau hauv lub npe ncaj qha hais tus nqi no.
Tensile zog (Rm): 360 - 510 MPa
Qhov no yog qhov siab tshaj plaws uas cov hlau tuaj yeem tiv taus thaum ncab ua ntej nws tawg. Qhov ntau qhia qhov sib npaug ntawm lub zog thiab ductility.
Qhov sib txawv tiag tiag: Qhov "J2" Qhov Zoo
Thaum nws lub zog yog tus qauv, lub ntsiab lus"J2"yog qhov teeb tsa S235J2W sib nrug rau kev siv tswv yim. Nws qhia txog cov khoom sivcuam tshuam toughness.
S235J0W: Guarantees tsawg kawg nkaus lub zog ntawm 27 Joules ntawm0 degree.
S235J2W: Guarantees tsawg kawg nkaus lub zog ntawm 27 Joules ntawm-20 degree.
Qhov no txhais tau tias S235J2W tau ntawv pov thawj los tiv thaiv cov pob txha tawg hauv qhov chaw txias dua, ua rau nws muaj kev nyab xeeb dua thiab txhim khu kev ntseeg ntau dua rau cov qauv hauv cheeb tsam nrog lub caij ntuj no khov lossis rau cov ntawv thov raug rau cov khoom hnyav.
Phau Ntawv Qhia Xaiv Tswv Yim
Kev xaiv ntawm S235J0W thiab S235J2W tsis yog hais txog lub zog- nws yog hais txog kev tawv tawv rau koj qhov kev nyab xeeb thiab daim ntawv thov:
Rau General, Kho kom zoo nkauj, lossis huab cua me me: S235J0Wfeem ntau txaus thiab tus nqi- zoo rau façades, architectural nta, lossis tsis yog - cov qauv tseem ceeb hauv cov cheeb tsam uas muaj lub caij ntuj no.
Rau kev siv hauv cov cheeb tsam txias: S235J2W yog qhov kev xaiv meej.Yog tias koj qhov project yog ib qho kev thauj khoom -cov khoom muaj xws li cov kab kev txhawb nqa, tus choj txuas, lossis ib qho qauv hauv qhov chaw uas qhov kub thiab txias tsis tu ncua, qhov lav tau tias -20℃toughness yog qhov tsis tuaj yeem sib tham txog kev nyab xeeb.
Nco ntsoov xyuas nrog Mill Certificate: Rau txhua qhov kev tsim qauv, ib txwm thov cov khoom siv daim ntawv pov thawj zeb xeem. Cov ntaub ntawv no tau lees paub tias cov khoom xa tuaj ua tau raws li qhov yuav tsum tau muaj 235 MPa yield zog thiab, qhov tseem ceeb, -20℃cuam tshuam lub zog tus qauv.
Cov ntsiab lus
S235J2W Corten steel muab qhov tsawg kawg nkaus lub zog ntawm 235 MPa thiab lub zog tensile ntawm 360-510 MPa, sib piv cov qauv qib. Nws cov txiaj ntsig zoo tshaj plaws nyob rau hauv nws qhov kev lav phib xaub mus rau -20 degree, ua rau nws muaj ntau yam thiab muaj kev nyab xeeb rau kev siv cov txheej txheem raug huab cua txias. Rau cov dej num hauv cov huab cua khov, qhia txog qib "J2" yog ib qho yooj yim, cov kauj ruam tseem ceeb rau kev ua kom muaj kev ncaj ncees mus ntev.
