Raws li 3679 qib300

Raws li 3679 qib 300 yog cov txheej txheem steel txheej txheem sib txawv siv hauv kev tsim kho thiab engineering hauv Australia. Nws yog ib feem ntawm cov qauv 3679, uas qhia meej txog qhov yuav tsum tau ua rau kub-rolled qauv qauv txheej txheem, toj siab, thiab kab.

Cov Khoom Siv Tseem Ceeb

Cov khoom siv neeg kho mob ntawm ua 3679 qib 300 yog tsim los ua kom tau raws li qhov xav tau ntawm cov ntawv thov cov txheej txheem:

• Paib lub zog: Tsawg kawg 300 MPa
• Lub zog tensile: Yam tsawg kawg 440 MPA
• Elongation: Yam tsawg kawg nkaus 22% (nyob ntawm seb lub tuab thiab hom steel)

Kev siv tshuaj lom neeg (raug) 

Cov tshuaj lom neeg muaj pes tsawg leeg ntawm ua 3679 qib 300 yog nruj me ntsis tswj tau kom muaj cov khoom siv neeg siv cov khoom siv uas zoo ib yam. Cov ntsiab lus siab tshaj plaws ntawm cov ntsiab lus tseem ceeb yog raws li hauv qab no:

• Cov pa roj carbon (c):0.25%
• Silicon (si): 0.5%
• Manganese (MN): 1.6%
• Phosphorus (p):0.04%
• Sulphur (s):0.04%
• Lwm cov ntsiab lus:Cov nyiaj ntawm txhuas, Niobium, lossis Vanadium yuav ntxiv rau cov khoom siv qoob loo.

Hwj txwv

• Zoo WeldabilityVim yog cov ntsiab lus muaj roj carbon tsawg.
• Yuav tsum muajYog tias:

Tuab>25-30 hli(kom tsis txhob muaj hydrogen cracking).

Ambient Kub <5 degree.

• Pom zoo vuam txoj kev:

Smig (Lo), GMaw (MIG), FCAW (flux-cored), pom (submerged arc).

Machining & Sib Sau

• Luam Ntawv Ntsuas:~ 60% (piv rau cov hlau dawb).
• Bendability:Yam tsawg kawg nkaus khoov radius ~ 1.5 × tuab (rau 90 degree txias dabtsi yog khoov).

Kev kho cua sov (yog tias yuav tsum tau)

• Kub Rolled: Cov hlau xa tawm hauv nws cov mob uas tsis muaj kev kho cua sov ntxiv.
• Zoo li cas: Cov qauv hlau yuav yog qhov ua kom ua kom zoo rau cov qauv grain thiab txhim kho cov khoom siv neeg txhua yam. Tus txheej txheem no cuam tshuam nrog cua sov cov hlau mus rau qhov ntsuas kub tshwj xeeb thiab tom qab ntawd txias nws maj mam hauv huab cua.

Txhawm rau kom ua raws li AS / NZS 3679.1, qib 300 hlau undergoes nyuaj heev

• Tshuaj Ntsuam Xyuas Tshuaj:Los xyuas cov tshuaj lom neeg muaj pes tsawg leeg.
• Kev Kuaj Neeg Kho:Tensile thiab cuam tshuam kev ntsuam xyuas kom paub meej lub zog thiab tawv.
• Kev Soj Ntsuam thiab Kev Pom Zoo:Txhawm rau kom cov hlau ua tau raws li qhov ntev thiab yog pub dawb los ntawm qhov tsis xws luag.

Qib 300 hlau yog haum rau ntau cov ntawv thov vim nws lub zog sib npaug thiab kev sib luag

• Kev Tsim Kho:Siv hauv tsev qauv qauv, txuas hniav, thiab cov phiaj xwm infrastrasure.

• Tsheb thauj mus los:Feem ntau siv nyob rau hauv cov ciav hlau ciav hlau, cov khoom siv tsheb, thiab lwm yam kev lag luam ntsig txog kev thauj khoom.

• Kev Kuaj Neeg Kho Tshuab: Tensile thiab cuam tshuam kev ntsuam xyuas kom paub meej tias muaj lub zog thiab tawv.

Hauv cov ntsiab lus, xws li / NZS 3679 Qib 300 hlau yog ib qho khoom siv ntau thiab txhim khu kev qha thiab cov khoom siv txhim khu kev qha uas haum rau cov ntawv thov kev tsim qauv ntau yam. Nws cov khoom siv sib npaug thiab kev tswjhwm nruj nruj ua rau nws xaiv qhov kev xaiv hauv Australian thiab New Zealand lag luam.
