Dab tsi yogSIB 36cov khoom sib npaug?
Kev nkag siab txog qhov sib npaug rau SA-36 / A36 yog qhov tseem ceeb rau kev yuav khoom thoob ntiaj teb, kev hloov pauv tsim, thiab hloov khoom siv.
Lub tswv yim tseem ceeb tshaj plaws yog tias tsis muaj ib qho, zoo meej, muaj ntawv pov thawj zoo li A36. Qhov kev xaiv ntawm "sib npaug" nyob ntawm seb cov cuab yeej twg yog qhov tseem ceeb tshaj plaws rau koj daim ntawv thov: yam tsawg kawg nkaus lub zog, tshuaj muaj pes tsawg leeg, los yog guaranteed tej yam toughness.
SA36 khoom yog dab tsi?
SA36 yog hais txog tus qauv nrov, ntau yam carbon structural steel (ASME SA36) siv hauv kev tsim kho, txuas hniav, thiab kev tsim khoom, zoo ib yam hauv cov khoom rau ASTM A36 steel, tab sis nrog ASME ntawv pov thawj rau kev siv hauv boilers thiab siab hlab ntsha, txhais tau tias nws dhau mus kuaj nruj dua rau siab - kev siv bolting, tsim nyog rau kev siv, kev siv zog, thiab kev siv zog. kev tsim kho. Nws paub txog lub zog zoo (tsawg kawg 36 ksi yield) thiab formability, nrog rau kev siv los ntawm cov cav tov rau tso tsheb hlau luam.
Nov yog cov ncauj lus kom ntxaws ntawm SA-36 / A36 sib npaug ntawm cov qauv sib txawv.
Ceev Reference: Sib npaug rooj
| Txuj | Qhov sib npaug ze tshaj plaws | Qhov Tseem Ceeb Qhov txawv & Cov Lus Cim |
|---|---|---|
| Teb chaws Europe (EN) | S235 JR S235J0 / S235J2 |
Tsis yog kev sib tw ncaj qha. Saib qhov kev ntsuam xyuas tseem ceeb hauv qab no. |
| International (ISO) | Fe 360-B / E235-B | Ntau dhau los ntawm EN cov qauv. Zoo ib yam li S235 series. |

Xaus rau EN Equivalents:
Rau Kev Sib Tw Muaj Zog: Qhov sib tw ze tshaj plaws yog S275 (275 MPa tawm los). Txawm li cas los xij, S275 muaj chemistry nruj dua.
Rau Lub Hom Phiaj / Daim Ntawv Thov Kev Sib Tw: S235JR lossis S235J2 yog siv rau hauv cov tsev thiab cov qauv zoo sib xws. S235J2 (kev cuam tshuam ntawm -20 degree) feem ntau yog ib qho kev ua haujlwm zoo dua li S235JR vim nws txoj kev xyaum steel tua thiab lav qhov tawv tawv ntawm ob ntawm A36 qhov tsis muaj zog.
Rau Vuam / Chemistry Matching: Tsis muaj qhov sib npaug ncaj qha. A36's chemistry yog ze rau qee qib S275 tab sis muaj zog sib txawv.
Yuav ua li cas xaiv qhov tseeb "Sib npaug" txog SA36
Qhov kev xaiv zoo nyob ntawm tus qauv tsim qauv thiab cov cuab yeej tseem ceeb:
Yog hais tias tus tsim yog tswj los ntawm Yield Strength (xws li, ib tug American tsim yog fabricated txawv teb chaws):
Koj xav tau cov khoom siv nrog lub zog ua kom muaj zog ntau dua lossis sib npaug li 250 MPa. Hauv EN system, qhov no taw qhia koj rau S275JR lossis S275J2.
Koj yuav tsum rov- pom zoo tsim nrog cov khoom tshiab cov khoom muaj tseeb (uas tuaj yeem hloov pauv cov tswv cuab ntau thiab tsawg).
Yog tias Daim Ntawv Thov yog Kev Tsim Kho General (piv txwv li, lub tsev khaws khoom, tsis yog- qhov tseem ceeb):
Qhov chaw muaj nyob hauv zos thiab tus nqi txiav txim, S235JR/J2 (EU) lossis Q235B (Tuam Tshoj) feem ntau lees txais tias "kev lag luam sib npaug" vim tias lawv ua haujlwm tib lub hom phiaj. Qhov no yuav tsum tau kev pom zoo engineering.
Yog tias Tsawg-Temperature Toughness yog qhov tseem ceeb (piv txwv li, sab nraum zoov qauv hauv huab cua txias):
Standard A36 yog ib qho kev xaiv tsis zoo (tsis muaj qhov yuav tsum tau muaj zog).
Qhov sib npaug yuav tsum yog qib nrog qhov yuav tsum tau muaj kev ntsuam xyuas, xws li S235J2 (-20 degree) lossis, kom muaj zog zoo dua, S275J2.
Yog tias Weldability yog qhov kev txhawj xeeb tseem ceeb:
Cov qib European (S235, S275) nrog lawv cov ntsiab lus qis carbon yog qhov zoo dua thiab zam txim ntau dua li A36.
Summary : Txoj Lus Teb
Hauv European/International cov ntsiab lus, feem ntau lees txais kev ua haujlwm lossis kev lag luam sib npaug rau kev siv dav dav yog S235 series (JR, J0, J2) thiab S275 series rau lub zog-match applications.
Hauv cov ntsiab lus Asian, Q235B (Tuam Tshoj) lossis SS400 (Nyiv) yog cov qauv sib npaug.
Qhov tseem ceeb, "sib npaug" tsis txhais hais tias "kev sib hloov tsis tau tshuaj xyuas."
Rau kev hloov pauv, koj yuav tsum muaj: 1) Kev pom zoo los ntawm lub luag haujlwm tsim engineers, 2) Cov ntawv pov thawj zeb xeem ntawv rau cov khoom siv tiag tiag, thiab 3) Cov txheej txheem vuam hloov tshiab yog tias cov tshuaj sib txawv.
Kev Txiav Txim Zaum Kawg: Qhov tseeb "sib npaug" yog txiav txim siab tsis yog los ntawm lub rooj yooj yim, tab sis los ntawm cov phiaj xwm tshwj xeeb, cov cai tswj hwm, thiab kev ntsuam xyuas cov khoom ntawm cov khoom siv uas tsis yog - sib tham. Nco ntsoov sab laj ib tus kws tsim khoom siv khoom lossis tus tsim qauv tsim ua ntej hloov.
1. Dab tsi yog SA36 steel feem ntau siv rau?
SA36 yog qhov dav siv dav tshaj plaws - lub hom phiaj steel qauv nyob rau hauv North America, feem ntau yog ua hauj lwm nyob rau hauv lub tsev thav duab, txuas hniav, cov cuab yeej siv, thiab cov fabrication dav uas yuav tsum tau muaj zog thiab weldability zoo.
2. Lub zog ntawm SA36 steel yog dab tsi?
SA36 muaj qhov tsawg kawg nkaus tawm lub zog ntawm 36,000 psi (250 MPa), uas yog lub hauv paus rau nws lub npe ("36") thiab ua rau nws haum rau ntau yam ntawm cov qauv siv.
3. Puas yog SA36 steel weldable?
Yog lawm, SA36 yog weldable heev siv txoj kev zoo li SMAW, GMAW, thiab FCAW. Txawm li cas los xij, preheating tej zaum yuav tsim nyog rau cov seem tuab los yog cov pob qij txha uas tsis muaj zog vim nws cov ntsiab lus carbon tsis sib xws.
4. SA36 txawv ntawm SA572 Qib 50 li cas?
SA36 muaj lub zog qis dua (36 ksi vs . 50 ksi) thiab yog cov pa roj carbon steel, thaum SA572 Qib 50 yog siab - zog qis- alloy (HSLA) steel nrog lub zog zoo dua - rau - qhov hnyav piv thiab atmospheric corrosion kuj.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
