Thaum sib pivA572-50 H nqajthiab A572-55 H beam, ntau tus neeg yuav khoom xav tias qhov txawv me me. Hauv kev muaj tiag, qhov kev hloov me me hauv qib no tuaj yeem cuam tshuam rau cov qauv kev ua tau zoo, kev ua haujlwm ntawm cov khoom siv, thiab cov tswv yim yuav khoom.
A572-50 H nqaj
Ob qib yog ASTM A572 siab-lub zog qis- alloy steel, tab sis lawv cov khoom siv kho tshuab tsis zoo ib yam. Qhov tseem ceeb tshaj qhov txawv yog nyob rau hauv lub zog, uas ncaj qha txiav txim siab npaum li cas cov hlau yuav siv tau nyob rau hauv ib tug qauv.
| Khoom | A572-50 H Beam | A572-55 H Beam |
|---|---|---|
| Yield zog | Ntau dua lossis sib npaug rau 345 MPa (50 ksi) | Ntau dua lossis sib npaug rau 380 MPa (55 ksi) |
| Tensile zog | 450-620 MPa | 490-650 MPa |
| Elongation | Ntau dua lossis sib npaug li 18% | Ntau dua lossis sib npaug li 17% |
Los ntawm lub rooj, nws pom tseeb tias A572-55 H beam muab txog 10% siab zog tawm los ntawm A572-50 H beam. Qhov kev nce no yuav zoo li me me, tab sis hauv kev tsim qauv, nws tso cai rau cov kws ua haujlwm kom txo qis qhov loj me, txhim kho qhov hnyav, thiab txhim kho kev ua haujlwm ntawm cov kabmob. Rau cov phiaj xwm loj xws li txuas hniav lossis cov chaw ua haujlwm hnyav, qhov no tuaj yeem txhais ua kev ntsuas kev txuag nyiaj hauv kev siv hlau.
Txawm li cas los xij, lub zog siab dua tsis tau txhais tau tias kev xaiv zoo dua. Hauv kev yuav khoom, kev ua haujlwm yuav tsum sib npaug nrog tus nqi thiab muaj. A572-50 H beam tseem yog qib feem ntau siv thoob ntiaj teb vim tias nws muaj lub zog txaus rau feem ntau ntawm cov qauv siv thaum tuav cov khoom ruaj khov thiab cov nqi sib tw.
Qhov sib txawv no tau pom tseeb dua thaum peb saib ntawm -cov khoom siv hauv ntiaj teb tiag tiag:
| Yam | A572-50 H Beam | A572-55 H Beam |
|---|---|---|
| Muaj | Cov khoom dav dav | Cov khoom siv tsawg |
| Ntau lawm | Txheem dov | Feem ntau kev cai |
| Lub Sijhawm Lead | Luv luv | Ntev dua |
| Export siv | Feem ntau | Tsawg dua |
Hauv kev lag luam thoob ntiaj teb, cov xwm txheej no feem ntau tseem ceeb dua li lub zog nws tus kheej. A572-50 H beam tuaj yeem tau txais los ntawm ntau lub mills thiab cov neeg muag khoom sai sai, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm nrog cov sijhawm kaw. Nyob rau hauv sib piv, A572-55 H beam yog tsis tshua muaj stocked thiab tej zaum yuav xav tau kev cai ntau lawm, ua rau ob qho tib si txhuas lub sij hawm thiab kev pheej hmoo ntawm kev yuav khoom.
Tus nqi yog lwm qhov chaw uas qhov sib txawv ua ntau nuanced. Thaum A572-55 H beam muaj tus nqi siab dua ib tuj, nws lub zog siab dua tso cai rau txo cov khoom siv-tsawg kawg hauv txoj kev xav.
| Nqi Factor | A572-50 | A572-55 |
|---|---|---|
| Nqe ib Ton | qis | Siab dua |
| Yuav Tsum Muaj Ntau | Siab dua | qis |
| Tus nqi thauj khoom | Siab dua | qis |
| Tus nqi tag nrho ntawm qhov project | ruaj khov | Nyob ntawm tus tsim |
Lub ntsiab lus tseem ceeb ntawm no yog A572-55 tsuas yog ua tus nqi zoo thaum tus qauv tsim tau zoo. Yog tias ib qhov project tsuas yog hloov A572-50 nrog A572-55 yam tsis suav qhov ntau thiab tsawg, lub zog ntxiv yog nkim, thiab tag nrho cov nqi nce ntxiv. Qhov no yog ib qho ntawm feem ntau yuam kev ua los ntawm cov neeg yuav khoom thiab txawm tias qee tus neeg cog lus.
A572-50 H nqaj
Nyob rau hauv cov nqe lus ntawm kev siv, qhov txawv kuj yog cov tswv yim es tsis theoretical. A572-50 H beam yog dav siv nyob rau hauv cov tsev, warehouses, thiab standard infrastructure vim hais tias nws muab ib tug txhim khu kev qha sib npaug ntawm lub zog thiab tus nqi. A572-55 H beam, ntawm qhov tod tes, feem ntau yog tshwj tseg rau cov haujlwm uas qhov kev xav tau ntawm cov txheej txheem siab dua lossis qhov hnyav txo qhov tseem ceeb.
| Daim ntawv thov | Pom zoo Qib |
|---|---|
| Kev tsim kho dav dav | A572-50 |
| Cov tsev khaws khoom | A572-50 |
| Choj (standard load) | A572-50 |
| Heavy industrial lug | A572-55 |
| Siab -load infrastructure | A572-55 |
Thaum kawg, qhov sib txawv ntawm A572-50 H beam thiab A572-55 H beam tsis yog hais txog tus lej ntawm lub zog, tab sis hais txog yuav ua li cas lub zog haum rau tag nrho cov phiaj xwm phiaj xwm.
A572-50 muaj kev ruaj ntseg, muaj, thiab kev tswj tus nqi, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau feem ntau cov haujlwm thoob ntiaj teb. A572-55 muaj kev ua tau zoo dua thiab muaj peev xwm ua kom zoo dua qub, tab sis tsuas yog xa tus nqi thaum siv cov qauv tsim ua tib zoo.
A572-50 H nqaj
Rau cov neeg yuav khoom, txoj hauv kev ntse tshaj plaws tsis yog xaiv cov qib siab dua qhov muag tsis pom, tab sis txhawm rau ntsuas qhov xav tau ntawm cov khoom thauj, cov khoom siv, thiab tag nrho cov nqi tsaws ua ke. Qhov no yog qhov cais cov khoom siv tau zoo los ntawm kim tshaj - specification.
