EN 10210 S35J30H HLAU SEEM

Ntawm cov qauv steel tau teev nyob rau hauv EN 10210 tus qauv rau kub-tiav hollow cov khoom sib npaug (hss),S355J2Hyog cov feem ntau dav siv vim nws tau ua tiav zoo, kev ua tau zoo, thiab weldability. Cov qib kawm no tshwj xeeb yog siv rau hauv cov txheej txheem tsim qauv rau cov ntawv thov uas xav tau cov khoom muaj peev xwm siab thiab siv tau ntev. Hauv qab no yog cov ncauj lus kom ntxaws ntawm s355j2h, suav nrog nws cov tshuaj muaj pes tsawg leeg, cov cuab yeej siv cov neeg kho mob, thiab cov ntawv thov raug.

Cov tshuaj lom neeg muaj pes tsawg leeg ntawm S355j2H yog ua tib zoo tswj kom ntseeg tau cov khoom siv zoo thiab weldability. Lub ntsiab tseem ceeb muaj xws li:

Cov pa roj carbon (c):Tsawg dua los yog sib npaug rau 0. 22%

Manganese (MN):Tsawg dua los yog sib npaug rau 1.60%

Phosphorus (p):Tsawg dua lossis sib npaug rau 0. 035%

Sulphur (s):Tsawg dua lossis sib npaug rau 0. 035%

Silicon (si):Tsawg dua los yog sib npaug rau 0. 55%

Cov ntsiab lus muaj roj carbon tsawg kom muaj txiaj ntsig zoo ntxiv, thaum cov ntsiab lus manganese ua rau muaj zog thiab tawv. Cov qib qis ntawm phosphorus tsawg ntawm phosphorus thiab leej faj tsawg tsis tshua muaj kev pheej hmoo ntawm brittleness thiab txhim kho tag nrho cov.

S355J2H paub txog nws lub zog siab thiab kev muaj zog heev, ua rau nws haum rau cov ntawv thov tsim qauv. Nws cov khoom tseem ceeb muaj xws li:

Paib lub zog (rov qab):Ntau dua los yog sib npaug rau 355 mpa

Tensile Lub Zog (RM):470-630 mpa

Elongation (a):Ntau dua los yog sib npaug rau 22% (rau thickness tsawg dua los yog sib npaug rau 16 hli)

Kev Cuam Tshuam Cov:

Charpy V-nthuav tawm kev sim ntawm -20 degree: ntau dua los yog sib npaug rau 27 j

Cov khoom no ua kom paub tseeb tias S355j2h tuaj yeem tiv thaiv siab thiab cov zog ntawm cov zog, txawm tias tsis tshua muaj cua sov.

Siab zog-rau-hnyav piv:

S355j2H muab cov kev zam tsis zoo nrog qhov hnyav tsis zoo, ua rau nws zoo tagnrho rau cov qauv loj thiab cov tsev nce siab.

Zoo heev Weldability:

Cov tshuaj tswj cov tshuaj muaj pes tsawg leeg, tshwj xeeb yog cov ntsiab lus carbon tsawg, ua kom pom tseeb tias s355j2h tuaj yeem muab tso rau nws cov khoom siv tshuab.

Kev Cuam Tshuam Cov:

Cov qhab nia qhab nia zoo nyob rau hauv cov khoom siv hluav taws xob zoo thiab kub kub, ua rau nws haum rau cov chaw hnyav xws li cheeb tsam ntug dej thiab cov cheeb tsam txias.

Qhov Tseeb Docensional:

EN 10210 qhia meej meej txog kev zam rau S355j2H, ua kom muaj kev ntseeg siab thiab muaj txiaj ntsig zoo nyob rau hauv cov khoom lag luam.

Zoo Tshaj:

Tus qauv yuav tsum muaj cov npoo du ua tiav, pub dawb los ntawm qhov tsis xws luag uas tuaj yeem ua rau muaj kev ncaj ncees.

S3555J2H tau siv dav hauv ntau cov ntawv thov txheej txheem, suav nrog:

High-Rose Vaj Tse:

Txhua, kab teeb, thiab kev coj ua uas xav kom muaj zog thiab kav ntev.

Txuas hniav:

Loj-ntev thiab kev ua haujlwm loj ntawm cov qauv qauv.

Offshore qauv:

Platforms, Rigs, thiab lwm yam tub rog marrine.

Cov Chaw Muaj:

Cov cuab yeej siv cov tshuab ua ke, txhawb nqa, thiab conveyor tshuab.

Chaw ntau pob thiab cov Arenas:

Ru tsev trusses thiab cov txheej txheem tshiab loj.

S355j2h yog cov feem ntau siv steel qib hauv EN 10210 vim nws lub zog zoo dua, kev muaj zog, thiab weldability. Nws yog cov khoom siv ntawm kev xaiv rau cov txheej txheem txheej txheem hnyav, suav nrog cov vaj tse siab, txuas hniav, thiab sab nrauv qauv. Kev tswj nruj ua kom nruj thiab haum cov qauv tsim kom paub meej tias S355J2h ua kom tau raws li cov kev ua tau zoo tshaj plaws, ua rau lawv xaiv ntau yam rau cov txheej txheem kev tsim kho niaj hnub.
