S355M Kub Rolled Carbon Hlau H Be Be

S355m kub dov carbon hlau h-nqaj yog lub zog siab, tsawg alloy qauv hlau khoom qub siv hauv kev tsim kho, engineering thiab kev siv khoom siv.

S355m carbon hlau h-nqaj ntog hauv qab en {2}} qauv kev mobile kev mob rau cov qauv vaj tsev. Qhov "S" hauv S355m sawv rau cov qauv hlau, "355" sawv rau qhov tseeb tias nws tau tsim los ntawm cov txheej txheem thermomechanical, uas txhim kho cov khoom siv me thiab weldability.

S355M H-Nqaj yog tsim los ntawm kub dov raws los ntawm thermomechanical kev kho mob. Tus txheej txheem cuam tshuam:
Cua sov: lub phaj steel yog rhuab rau qhov kub siab (kwv yees li 1100-1250 degree).
Rolling: cov slab tau tsim rau hauv H-puab cov ntaub ntawv los ntawm yob cov chais, thiab cov dov rau qhov kub thiab txias yog tswj kom tau kho cov qauv nplej.
Txias: Cov kab teeb tau txias raws li cov haujlwm tshwj xeeb kom lawv ua kom lawv cov khoom siv kho tshuab.
Txoj kev no ua kom muaj kev sib tw hla-ntu, siab qhov tseeb yog thiab txhim kho kev ua tau zoo sib piv rau cov hlua kub uas siv cov hlua kub.

Qhov Zoo ntawm S355M Kub-Rolled H-Beams
Siab zog: tsawg kawg yog los lub zog muaj zog ntawm 355 MPa txhawb cov khoom hnyav.
Weldability: tsawg cov pa roj carbon muaj txiaj ntsig qhov tseem ceeb tau yooj yim vuam yam tsis muaj preheating feem ntau.
Tougness: kev cuam tshuam zoo heev ntawm sub-xoom kub (-20} degree lossis qis dua).
Nqi-txiaj ntsig: muab kev sib npaug ntawm kev ua tau zoo thiab pheej yig rau cov phiaj xwm loj.
Sustainability: ThermieManical dov txo cov zog kev siv hluav taws xob piv rau cov qauv steel.

Kev sib piv nrog lwm qib
S3555j2 (en 10025-2}): Vim yog thermomechanical dov, s355m muaj kev nruj zoo dua thiab weldability, thaum s355j2 yog li qub lossis dov.
S275M: muaj qis zog zog zog zog (275 MPa) dua li S355m, ua kom yav tom ntej tsim rau cov ntawv thov ntau dua.
S420M: muaj lub zog siab dua (420 mpa), tab sis tej zaum yuav txo qis ductility dua li s355m, nyob ntawm daim ntawv thov.

Gnee steel tau tsim tsa nyob rau xyoo 2008, peb cov khoom tseem ceeb yog seem steel, lub tsev sib luag, thiab lwm yam. Peb zoo siab los muab koj tus nqi zoo tshaj plaws thiab cov lus qhia. Koj zoo siab tos txais koj mus ntsib peb lub tuam txhab.
