Raws li 3679 tus qauv

Raws li 3679 yog tus qauv Australian uas qhia txog cov kev cai tshuaj lom neeg, cov khoom siv neeg siv cov neeg siv tshuab, thiab kev tawm tsam ib qho chaw ntawmTxheej txheem steelSiv hauv kev tsim kho, engineering, thiab tsim cov ntawv thov. Nws npogKub-Rolled qauv txheej txheem hlau, tuav, thiabfeem, kom ntseeg tau tias lawv tau ua tiav qhov tsim nyog ua tau zoo thiab ua tau zoo rau cov khoom siv thauj khoom.

Tus qauv siv rauCov pa roj carbon thiab carbon-manganese steelsmuab nyob rau hauv cov ntawv hauv qab no:

• Kub-Rolleded Daim Hlau, Ntawv Qhia, Thiab Strips
• Kub-rolled cov qauv txheej txheem (piv txwv li, kab teeb, raws, cov ces kaum)
• Tuav rau kev siv cov qauv

Nws tsis npog txias-tsim steel (uas poob qis raws li 1163) lossis stainless hlau.

Cov qauv ntawm cov hlau ua rau ntau qib rawspaib lub zog, tensile lub zog, thiab ductility:

Carbon Stades

• Raws li 3679 Qib 250: Yam tsawg kawg los kom muaj zog ntawm250 MPa, haum rau cov qauv kev siv dav dav.
• Raws li 3679 qib 300: Yam tsawg kawg los kom muaj zog ntawm300 mpa, feem ntau siv nyob rau hauv cov tuam tsev thiab txuas hniav.
• Raws li 3679 qib 350: Lub zog siab (350 MPa tawm los), siv hauv cov qauv hnyav.

High-zog tsawg-alloy (hsla) cov qib

• Raws li 3679 Qib 400 & 450: Txhim Kho Lub Zog (400-450 MPA tawm los) rau cov ntawv thov tsim qauv.

Tshuaj Muaj Tshuaj

Tus qauv txhais cov kev txwv rau cov ntsiab xws li:

• Carbon (c)- Cuam tshuam cov hardness thiab weldability.
• Manganese (mn)- Txhim kho lub zog thiab tawv.
• Phosphorus (p) & leej faj (s)- Txwv tsis pub kom ntseeg tau Weldability thiab Ductility.
• Alloying Ntsiab(nyob rau qib sau) rau corrosion tsis kam.

Tus txheej txheem qhia txog cov tshuaj lom neeg tshuaj lom neeg ntawm cov hlau, suav nrog cov pa roj carbon (c), manganese (mn), leej faj (p). Piv txwv li, nyob rau hauv AS3679. {{1 300}}}}}} 0%, thiab cov neeg Sulfur cov ntsiab lus tsawg dua 0.0400%.

Cov Khoom Siv Neeg Kho Tshuab

Qhov tseem ceeb yuav tsum muaj xws li:

• Yield zog (mpa)- Qhov tsawg kawg nkaus ntxhov siab ntawm cov hlau deforms mus tas li.
• Tensile lub zog (mpa)- Kev ntxhov siab tshaj plaws ua ntej tsis ua haujlwm.
• Elongation (%)- Kev ntsuas ductility.
• Charpy cuam tshuam Kev Ntsuas(Rau qee qib) - ntsuas kev nruj ntawm cov kub tsawg.

Txhawm rau kom ua raws li raws li 3679, cov khoom lag luam steel yauv ua kom nruj:

Tshuaj Lom: Los xyuas cov tshuaj lom neeg muaj pes tsawg leeg.

Kev Kuaj Neeg Kho Tshuab: Suav nrog tensile thiab cuam tshuam kev ntsuas kom paub meej lub zog thiab tawv.

Kev Soj Ntsuam Sab Hauv Thiab Kev Pom Zoo: Los xyuas kom cov hlau ua tau raws li qhov ntev thiab yog pub dawb los ntawm qhov tsis xws luag.

Raws li 3679 hlau yog siv nyob rau hauv ntau cov ntawv thov, suav nrog:

Kev tsa tsev: Rau tsev qauv qauv, txuas hniav, thiab vaj tse.

Engineering: Hauv kev tsim khoom, tshuab, thiab khoom siv.

Kev mus: Rau cov ciav hlau ciav hlau, cov khoom siv tsheb, thiab lwm yam kev thauj mus los ntsig txog.

Raws li 3679 yog cov qauv kev ua kom ntseeg tau cov khoom siv steel hlau tau sib ntsib cov qauv zoo thiab kev ua tau zoo. Nws yog dav pom thiab siv nyob rau hauv Australian thiab New Zealand lag luam rau nws txoj kev ntseeg tau thiab haum rau kev siv engineering.
