S355JR vs ASTM A36: Qhov Sib Txawv Tseem Ceeb thiab Yuav Ua Li Cas Xaiv Cov Hlau Tsim Kho Kom Zoo

1. S355JR thiab ASTM A36 yog dab tsi?

S355JR hlau vs A36 HLAU:

S355JR thiab ASTM A36 yog ob hom hlau qauv nrov tshaj plaws uas siv dav hauv ntiaj teb rau kev siv hauv kev tsim kho.

S355JR yog qib ntawm EN 10025, thaum ASTM A36 yog qib rau ASTM, uas yog cov qauv lees paub tshaj plaws hauv Tebchaws Meskas thiab qee qhov chaw ntawm lub ntiaj teb. Ob qib no tuaj yeem pom hauv cov ntawv thov zoo sib xws, tab sis lub tswv yim tom qab kev tsim qauv, kev xeem xav tau, thiab kev ua haujlwm kho tshuab txawv heev.

2. Kev sib piv ntawm cov khoom siv kho tshuab

Vaj tse S355JR (EN 10025) ASTM A36
Lub Zog Tsawg Kawg Nkaus 355 MPa 250 MPa
Lub zog tensile 470–630 MPa 400–550 MPa
Kev Ntsuas Kev Cuam Tshuam Yuav tsum tau (JR: 20 ° C) Tsis tas yuav tsum ua
Kev vuam tau Zoo heev Zoo

Qhov sib txawv loj tshaj plaws yoglub zog tawm los.

Lub zog ntawm cov khoomS355JR yog li 40% ntau dua li qhov muaj zog ntawm ASTM A36 uas txhais tau tias cov ntu ntawm cov qauv tuaj yeem ua kom sib dua lossis cov khoom thauj tuaj yeem nce ntxiv..

3. Kev Cuam Tshuam thiab Kev Nyab Xeeb ntawm Cov Qauv

S355JR suav nrog kev sim Charpy impact (JR qib ntawm + 20 ° C), uas muab kev ua tau zoo toughness kwv yees tau nyob rau hauv cov xwm txheej dynamic loading.
Tsis muaj qhov yuav tsum tau ua rau muaj kev ntsuam xyuas kev cuam tshuam rau ASTM A36, tshwj tsis yog tus neeg yuav khoom hais li ntawd hauv daim ntawv xaj yuav khoom.
Yuav siv rau: dynamic loads vibration nruab nrab kub variations Siv rau hauv dynamic loading daim ntawv thov.
S355JR muaj kev lees paub ntau dua rau kev ntseeg tau.

4. Cov Ntawv Thov Ib Txwm Muaj

S355JR

  • Cov choj thiab cov overpasses

  • Cov tsev siab siab

  • Cov platform kev lag luam

  • Cov thav duab tshuab hnyav

ASTM A36

  • Cov tsev qis qis

  • Kev tsim khoom dav dav

  • Cov phaj puag thiab cov brackets

  • Cov qauv tsis tseem ceeb ntawm kev thauj khoom

5. Yuav ua li cas txiav txim siab ntawm S355JR thiab A36?

S355JR yog qhov kev xaiv zoo dua yog tias:

Txo qhov hnyav ntawm cov qauv yog qhov tseem ceeb
Cov kev nyab xeeb ntawm kev nyab xeeb yuav siab dua
Lawv tau ua raws li cov qauv EN hauv qhov project

Xaiv ASTM A36 yog tias:

Tus nqi yog qhov tseem ceeb tshaj plaws
Cov khoom thauj khoom yog lub teeb heev
Ua raws li ASTM.

6. Tej Yam Yuam Kev Uas Yuav Tsum Zam

Xav tias S355JR thiab A36 yog cov sib npaug ncaj qha

Tsis quav ntsej txog qhov yuav tsum tau ua kom muaj zog ntawm kev cuam tshuam

Siv A36 hauv cov qauv uas rhiab heev rau kev qaug zog

S355JR thiab ASTM A36 ua haujlwm zoo sib xws, tab sis lawv tsis tuaj yeem hloov pauv yam tsis muaj kev ntsuam xyuas engineering.
