Lub ASTM sib npaug ntawm S235JR Hlau, European Cov Qauv Txheej Txheem Hlau Txheej Txheem Hlau, yogASTM A36.
Cov no yog cov qib me me siv rau cov qauv txheej txheem dav dav thiab muaj cov khoom siv tshuaj sib xyaw zoo sib xws thiab cov khoom siv mechanies.
S235JR yog European Txuj Ci (EN 10025) Qib Qauv, dav siv hauv kev tsim kho thiab engineering.
ASTM A36 yog ib tus neeg siv dav hlau qib neeg hlau qib.
S235JR, raws li Per ...25, muaj tsawg kawg vim muaj lub zog ntawm 235 MPa, nrog cov khoom haum rau cov ntawv thov cov kev thov.
ASTM A36, feem ntau siv nyob rau hauv Asmeskas, muaj cov txiaj ntsig zoo sib xws (nyob ib ncig ntawm 250 MPa) thiab sib piv lub zog thiab kev sib piv, ua rau nws sib npaug sib npaug.
Txawm li cas los xij, qhov sib txawv me me hauv kev ntsuas tshuaj lom neeg thiab kev xeem ntawv yuav tsum muaj, yog li yuav tsum tau txheeb xyuas rau kev siv tshwj xeeb.
Steel s235jr vs A36 khoom siv hauv cov khoom siv tshuaj lom
Hlau S235jr VS A36 Cov Khoom Siv Hauv Cov Khoom Siv Neeg Kho
S235JR hlau thiab ASTM A36 feem ntau siv hauv kev tsim cov thav ntawv, txuas hniav, tshuab sib txuas, thiab cov ntawv thov txheej txheem txheej txheem.

Cov FAQ
Q: Puas yog ASTM A36 sib npaug rau S235JR?
A: Khoom siv sib npaug:
ASTM A36: ASTM A36 yog Asmeskas cov qauv roj teeb carbon cov hlau ua kom zoo nkauj, uas feem ntau siv nyob rau hauv cov ntawv thov txheej txheem txheej txheem. Nws yog qhov ze tshaj S235JR nyob rau hauv cov nqe lus ntawm cov tshuaj muaj kuab lom
Q: Suav sib npaug ntawm Astm A36?
A: Suav Q235
Cov hlau ATM A36 (FY=250 mpa} mpa) sib npaug rau cov neeg Suav Q235, tau siv rau cov ces kaum thiab ASTM A572 gr.
Q: yog S355JR sib npaug rau A36?
A: AFTM A36 thiab S355JR yog ob qho qauv hlau qib, tab sis A36 yog tus qauv Asmeskas, thaum S355jr yog European txheem. S3555jr feem ntau muaj cov txiaj ntsig ntau dua thiab lub zog tensile tshaj A36, ua rau nws tsim nyog rau cov ntaub ntawv uas xav tau cov xeeb ceem ntau dua.
Q: Qhov txawv ntawm Astm A36 thiab S275 li cas?
A: ASTM A36 vS S275JR - Dab tsi yog qhov txawv
ASTM A36 yog ua los ntawm carbon thiab qis -} alloy steel thiab muaj tsawg kawg lub zog ntawm 36,000 psi. S275JR, ntawm qhov tod tes, yog ua los ntawm carbon, manganese, thiab silicon steel thiab muaj tsawg kawg yog 27,000 psi. Qhov no txhais tau tias Astm A36 yog cov muaj zog dua, tab sis S275JR yog ntau dua cookile thiab muaj cov machinability ntau dua.
Q: Dab tsi yog S235JR cov khoom siv?
A: Steel qib S235JR yog cov nyiam dav dav siv thiab tshuab hlau uas tau ua raws li cov EN 10025 {}}} 2 qauv. Kev faib tawm: Tsis -} almoy qauv hlau. Cov khoom lag luam: semi-} cov khoom tiav, cov khoom lag luam ntev thiab cov khoom siv kub, tso quav.
