Daim ntawv qhia ua tiav ntawm S355JR Channel Steel

Nyob rau hauv lub ntiaj teb no ntawm structural engineering thiab kev tsim kho,S355JR channel steel(tseem hu ua U-channels, steel channels, lossis C-sections) tau tshwm sim los ua ib qho tseem ceeb tshaj plaws thiab txhim khu kev qha cov qauv duab.

S355JR channel steel

Tsim los rau cov haujlwm uas xav tau lub zog zoo heev- rau- qhov hnyav piv, zoo dua weldability, thiab architectural versatility, S355JR structural channels yog cov pob txha ntawm niaj hnub infrastructure, industrial fabrication, thiab steel ncej tsim.

S355JR channel steel yog qis- alloy, siab-tensile cov qauv steel seem ua raws li European Standard EN 10025-2. Tsis zoo li cov paib tiaj tus, cov channel geometry- muaj lub vev xaib dav thiab ob lub flanges-yog tsim tshwj xeeb los muab cov qauv kev nruj nruj thaum txo qhov hnyav tag nrho.

Qhov no ua rau S355JR steel channel seem zoo tagnrho rau kev thauj khoom-cov ntaub ntawv kabmob, kev txhawb nqa ncej, tshuab hauv paus, txuas hniav, thiab cov khoom thauj.

Lub npe alphanumeric S355JR muab cov ntaub ntawv tseem ceeb:

S: Kos npe rau cov qauv hlau.

355: Qhia qhov tsawg kawg nkaus tawm lub zog ntawm 355 MPa

JR: Qhia qhov cuam tshuam rau qib toughness, kuaj ntawm chav tsev kub (20 degree) nrog qhov tsawg kawg nkaus Charpy V-notch cuam tshuam lub zog ntawm 27J.

Kev ua tau zoo ntawm S355JR channel steel stems los ntawm nws ua tib zoo sib npaug tshuaj muaj pes tsawg leeg, uas ua kom nws yooj yim rau vuam thaum tuav lub zog siab.

Mechanical Performance Profile:

• Yield Strength: Ntau dua los yog sib npaug rau 355 MPa (rau thickness Tsawg dua los yog sib npaug rau 16mm)
• Tensile zog: 470 - 630 MPa
• Elongation: Ntau dua lossis sib npaug li 20-22%
• Impact Toughness: Ntau dua lossis sib npaug rau 27J ntawm 20 degree

Cov txiaj ntsig no ua rau S355JR cov qauv channel steel yog cov khoom siv zoo tshaj plaws rau cov qauv nruab nrab thiab hnyav.

Thaum muab S355JR channel steel, nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv ntawm tus ntoo khaub lig- cov qauv ntu uas txiav txim siab flange cov duab thiab cov qauv kev ua haujlwm:

UPN (European Standard Channels)

Feature tapered flanges (lub puab nto ntawm lub flange yog sloped). Feem ntau siv nyob rau hauv industrial lug thiab tsoos steel fabrication.
