Qhov sib npaug ntawm S355J0 steel channel yog dab tsi?

S355J0 tau dav lees paub tias yog qib ntsuas qib siab rau siab - lub zog cov qauv hlau hauv Europe. Txawm li cas los xij, hauv cov haujlwm engineering thoob ntiaj teb, cov khoom siv tshwj xeeb feem ntau sib txawv thoob plaws lub tebchaws xws li Asmeskas, Tuam Tshoj, Nyiv, thiab Is Nrias teb.

S355J0

Rau cov thawj coj ntawm kev yuav khoom thiab cov kws tsim qauv, kev nkag siab S355J0 channel steel sib npaug yog qhov tseem ceeb rau kev ua kom muaj kev sib raug zoo ntawm kev tsim, txo cov kev pheej hmoo ntawm kev yuav khoom, thiab ua kom lub ntiaj teb kev ua haujlwm zoo.

Ntawm GNEE Steel, peb muab cov khoom zoo -S355J0 cov qauv hlau zoo uas ua tau raws li lossis dhau ntau tus qauv thoob ntiaj teb, pab cov neeg yuav khoom thoob ntiaj teb ua kom hla kev hla - ciam teb cov khoom lag luam nrog kev ntseeg siab.

Ua ntej muab qhov sib npaug, nws yog ib qho tseem ceeb kom nkag siab tias yog vim li cas S355J0 channel steel (EN 10025-2) thiaj li tau siv dav hauv kev siv engineering.

Core Mechanical Properties ntawm S355J0 Channel Steel

• Yield Strength: Ntau dua lossis sib npaug rau 355 MPa (siab load-cov kabmob muaj peev xwm)
• Impact Toughness: 27J ntawm 0℃(J0 qib yuav tsum tau)
• Txheem: EN 10025-2 European structural steel qauv
• Daim ntawv thov: Welded structural thav duab, infrastructure, industrial lug

Kev sib xyaw ua ke ntawm lub zog siab + tswj qis- qhov kub thiab txias ua rau S355J0 yog ib qho ntawm cov qib zoo tshaj plaws steel qib rau sab nraum zoov thiab huab cua huab cua.

Thaum EN tus qauv S355J0 tsis muaj nyob hauv zos, cov kws ua haujlwm feem ntau tso siab rau cov qib sib npaug los ntawm cov qauv hauv cheeb tsam. Txawm li cas los xij, qhov sib npaug tiag tiag yuav tsum tau ua tib zoo saib xyuas ob qho tib si txhua yam khoom thiab cov kev xav tau ntawm cov tawv nqaij.

A. American Standard Equivalent (ASTM / ASME)

ASTM A572 Qib 50

• Qhov no yog qhov feem ntau lees txais US sib npaug rau S355J0 channel steel.
• Yield zog: ~ 345-345 MPa (50 ksi)
• Dav siv nyob rau hauv cov qauv thav duab thiab txuas hniav
• Weldability zoo heev thiab muaj

• Daim Ntawv Qhia Txog Kev Muag Khoom Engineering

Thaum lub zog muaj zog zoo sib xws, ASTM A572 tsis tas yuav lav 0℃cuam tshuam kev kuaj los ntawm lub neej ntawd. Yog tias yuav tsum tau hloov pauv, cov kws ua haujlwm yuav tsum thov kom Charpy V- ntsuas qhov ntsuas kub qis kom phim S355J0 kev ua haujlwm.

B. Suav Standard Equivalent (GB/T)

Q355B / Q345B (GB / T 1591)

• Q355B yog qhov hloov kho tshiab hloov tshiab rau Q345B
• Dav siv nyob rau hauv Suav infrastructure thiab steel siv
• Tus nqi siab -kev ua tau zoo piv rau cov haujlwm loj -

• Procurement Advantage ntawm GNEE Steel
