A36 vs S235JR vs S355JR: Xaiv cov qauv hlau zoo rau koj qhov project

Yog tias koj tab tom nrhiav cov qauv hlau rau koj qhov project tom ntej, koj yuav tau ntsib "peb loj" ntawm carbon steel: A36, S235JR, thiab S355JR. Txawm hais tias lawv yuav zoo li zoo ib yam, xaiv qhov tsis ncaj ncees lawm qib tuaj yeem ua rau tus nqi overruns, project qeeb, lossis txawm tias muaj teeb meem ua raws cai.

Raws li ib tus neeg muab khoom lag luam ntseeg siab, peb pab cov neeg siv khoom xaiv cov kev xaiv no txhua hnub. Cov lus qhia no txiav los ntawm qhov nyuaj, muab qhov tseeb, cov ntaub ntawv rau koj- sib piv kom ntseeg tau tias koj qhov project yog tsim los ntawm lub hauv paus zoo.

Ua ntej, cia peb qhia meej txog keeb kwm ntawm cov qib no. Lawv los ntawm ob qhov sib txawv, tab sis dav lees paub, cov qauv.

ASTM A36 (A36):Ib tus qauv Asmeskas los ntawm ASTM International. Nws yog ib qho ntawm feem ntau siv cov qauv hlau hauv North America thiab ntau thaj chaw.

EN 10025-2 (S235JR & S355JR):Ib tug European standard. Tus "S" qhia txog cov qauv hlau, tus lej (235, 355) qhia qhov tsawg kawg nkaus lub zog ntawm MPa, thiab cov lus xaus (JR, J0, J2, K2) qhia txog cov khoom muaj kev cuam tshuam toughness ntawm qhov kub thiab txias.

Qhov sib txawv tseem ceeb tshaj plaws yog nyob rau hauv lawv lub zog. Nov yog qhov sib piv ncaj qha:

Qhov Tseem Ceeb Takeaway: S355JR muaj kwv yees li 40% siab dua qhov muaj zog tshaj S235JR thiab A36. Qhov no txhais tau tias koj tuaj yeem siv cov khoom siv tsawg dua kom ua tiav tib yam kev ua haujlwm ncaj ncees, ua rau kev txuag nyiaj thiab cov txiaj ntsig zoo ntawm cov haujlwm loj.

Koj qhov project qhov xav tau, qhov chaw, thiab pob nyiaj siv yuav txiav txim siab qhov kev xaiv zoo tshaj plaws.

Xaiv ASTM A36 lossis S235JR thaum:

Koj tus qauv tsim tsis muaj zog - tseem ceeb.

Koj tab tom ua haujlwm ntawm kev tsim cov thav duab, lub hauv paus phaj, lossis cov hlua khi.

Tus nqi yog thawj tus neeg tsav tsheb, thiab koj tau ua qhov tseem ceeb ntawm cov khoom siv nyiaj txiag tshaj plaws.

Koj qhov project yog nyob rau hauv ib cheeb tsam uas ASTM lossis EN cov qauv tau teev tseg, feem. (A36 thiab S235JR feem ntau suav tias yog kev lag luam sib npaug).

Xaiv S355JR thaum:

Lub zog siab- rau- qhov hnyav piv yog qhov tseem ceeb (piv txwv li, hauv cov khoom hnyav- cov dej num, txuas hniav, lossis daim ntawv thov hauv ntug dej).

Koj yuav tsum tau txo qhov hnyav ntawm tus qauv yam tsis muaj kev cuam tshuam lub zog, muaj peev xwm txuag tau ntawm kev xa khoom, kev tsim khoom, thiab cov nqi hauv paus.

Koj tus qauv tsim hu rau qib siab dua ntawm cov hlau kom ua tau raws li kev ruaj ntseg nruj lossis cov qauv kev ua haujlwm.

Weldability thiab Formability:Tag nrho peb qib yog feem ntau weldable thiab formable. Txawm li cas los xij, S355JR yuav xav tau me ntsis ntxiv rau cov txheej txheem vuam vim nws lub zog ntau dua.

Muaj: Raws li tus neeg xa khoom thoob ntiaj teb, peb khaws cov khoom lag luam dav dav ntawm tag nrho peb qib. Txawm li cas los xij, kev muaj nyob hauv zos tuaj yeem sib txawv, yog li kev koom tes nrog tus neeg muag khoom nrog cov saw hlau thoob ntiaj teb muaj zog yog qhov tseem ceeb kom tsis txhob ncua sijhawm.

Impact Toughness (Lub "JR"): Cov lus "JR" rau S235JR thiab S355JR txhais tau hais tias lawv raug sim rau qhov cuam tshuam ntawm qhov kub thiab txias (20℃/ 68℃F). Rau cov haujlwm hauv qhov chaw txias, tej zaum koj yuav xav tau cov qhab nia zoo dua - qhov kub thiab txias, xws li S355J2 (kuaj ntawm -20 degree) lossis S355K2 (kuaj ntawm -40℃).

Tsis txhob cia kev xaiv cov khoom ua ib lub raj mis. Qhov yooj yim tshaj plaws los xyuas kom meej tias koj tab tom xaiv txoj cai yog sab laj nrog koj tus neeg xa khoom steel thaum ntxov.

Peb nyob ntawm no los pab.

Raws li tus kws tshaj lij hauv kev muab A36, S235JR, thiab S355JR cov qauv hlau rau cov haujlwm thoob ntiaj teb, peb tsis yog xaj xaj xwb-peb muab cov kev daws teeb meem. Peb tuaj yeem pab koj txheeb xyuas koj qhov project specs, pom zoo tus nqi tshaj plaws - cov khoom siv tau zoo thiab ua raws, thiab muab cov lus sib tw nrog cov sij hawm ua txhuas.
