Tus nqi ntawm S355JR S355J2 S355JO H Beam yog dab tsi

Nyob rau hauv 2026, lub ntiaj teb no kev tsim kho thiab hnyav structural steel lag luam tseem muaj kev hloov pauv tsis tu ncua. Txawm tiasS355JR H beamUa kom pom qhov ua tau zoo tshaj plaws -kev ua tau zoo hauv kev loj- cov txheej txheem loj, cov phiaj xwm choj, thiab cov tshuab ua haujlwm sab nrauv, cov neeg saib xyuas kev muag khoom txawv teb chaws tseem ntsib cov nqi tsis tu ncua vim cov nqi raw khoom, cov nqi carbon thoob ntiaj teb, cov nqi thauj khoom, thiab cov nqi pauv hloov pauv.

Raws li cov ntaub ntawv tshaj tawm kev lag luam tshiab rau xyoo 2026, kev hloov pauv ntawm cov nqi hlau hlau thoob ntiaj teb, cov nqi ntawm cov coking thee thiab cov seem hlau, nrog rau cov hlau emission txo thiab cov nqi se hauv Suav teb thiab cov teb chaws Europe, tseem yog qhov tseem ceeb tsav tsheb tam sim no cuam tshuam rau cov nqi qis - alloy structural steel.

S355 H ntu steel belongs rau qis- alloy siab- lub zog steel, ua raws li European EN 10025 tus qauv. Piv nrog rau cov pa roj carbon ib txwm muaj, S355 series muaj zog dua thiab thauj khoom -cov kabmob muaj peev xwm thaum tuav cov weldability zoo thiab ua haujlwm tau zoo.

Ua tsaug rau nws cov khoom siv kho tshuab zoo heev thiab tus nqi -kev ua tau zoo, S355 H- nqaj hlau yog dav siv hauv: kev tsim vaj tsev, choj engineering, cov nroj tsuag muaj, crane beams, machinery manufacturing, thiab loj steel qauv ncej.

Tsis pub dhau S355 series, S355JR, S355J0, thiab S355J2 yog cov qib lag luam tshaj plaws:

• S355JR: Kev cuam tshuam toughness Ntau dua lossis sib npaug ntawm 27J ntawm chav sov, haum rau kev siv cov qauv siv dav dav.
• S355J0: Kev cuam tshuam toughness Ntau dua los yog sib npaug rau 27J ntawm 0 degree, haum rau qis - qhov kub thiab txias.
• S355J2: Kev cuam tshuam lub zog ntau dua lossis sib npaug ntawm 27J ntawm -20 degree, haum rau cov cheeb tsam txias thiab cov ntawv thov tshwj xeeb engineering.

Cov qib no tau siv dav hauv Asia, Europe, Middle East, thiab South America, ua rau lawv cov ntaub ntawv tseem ceeb hauv kev tsim kho niaj hnub thiab kev lag luam steel.

S355JR, S355J0, thiab S355J2 yog qis- alloy siab- lub zog steels feem ntau siv hauv kev tsim kho thiab kev lag luam steel qauv. Lawv qhov sib txawv tseem ceeb yog nyob rau hauv kev cuam tshuam toughness ntawm qhov kub thiab txias, uas ncaj qha cuam tshuam rau lawv qhov haum rau ntau yam kev mob ib puag ncig thiab kev siv cov qauv.

Yuav ua li cas xaiv S355 H-beam steel:

• Rau kev tsim qauv: Yog tias koj qhov project nyob rau hauv qhov kub thiab txias yam tsis muaj qhov txias txias, S355JR yog tus nqi tshaj plaws - kev xaiv zoo.
• Rau qhov chaw txias me ntsis: Yog tias tus qauv yuav muaj qhov kub thiab txias ib puag ncig 0 degree, S355J0 muaj kev cuam tshuam zoo dua thiab kev nyab xeeb.
• Rau qhov txias heev lossis hnyav- daim ntawv thov kev ua haujlwm: S355J2 muaj qhov siab tshaj plaws qis- qhov kub thiab txias, ua rau nws tsim nyog rau cov txuas hniav, ntug dej hiav txwv platforms, lossis txias - cheeb tsam kev lag luam.

Cov neeg muab khoom ntawm S355 series H-beam steel tuaj yeem pab cov neeg siv khoom xaiv cov qib tsim nyog tshaj plaws (S355JR, S355J0, lossis S355J2) raws li daim ntawv thov zaum kawg, xws li kev tsim qauv, txias - cheeb tsam cov qauv, lossis hnyav- lub luag haujlwm kev lag luam. Kev xaiv qib kom zoo pab kom tsis txhob muaj kev pheej hmoo ntawm kev nyab xeeb ntawm cov qauv thiab cov nqi tsis tsim nyog overruns los ntawm kev siv cov qib steel tsis tsim nyog.

Mill Test Certificate (MTC):
Txhua batch ntawm cov hlau yog muab nrog Lub Hoobkas Kev Xeem Ntawv Pov Thawj ua raws li EN 10204 3.1, uas qhia meej meej cov tshuaj muaj pes tsawg leeg (C, Mn, Si, P, S, Cr, Ni cov ntsiab lus) thiab cov khoom siv kho tshuab, ua kom tag nrho traceability thiab kev ruaj ntseg zoo.

Kev soj ntsuam zoo:
Ua ntej tawm hauv lub Hoobkas, tus neeg muag khoom lub chaw tswj xyuas kev ua tau zoo ua qhov kev tshuaj xyuas thib ob los xyuas kom meej:

• Dimensional kam rau ua (qhov siab, flange dav, web thickness)
• Ncaj thiab nto tiav
• Zuag qhia tag nrho kev sib xws

Qhov no ua kom ntseeg tau tias txhua H-beam ua tau raws li ob qho kev qhia tshwj xeeb thiab kev cia siab zoo rau kev tsim kho thiab kev lag luam.
