EN Standard S690 Kub- dov siab -lub zog steel phaj

S690 hlaupaub txog nws lub zog yield zog, feem ntau yog li ntawm 690 MPa rau 960 MPa, uas tso cai rau cov seem thinner hauv cov qauv siv yam tsis muaj kev cuam tshuam lub zog. Cov yam ntxwv no tsis tsuas yog txo qhov hnyav ntawm cov qauv, tab sis kuj ua rau kev txuag nqi ntawm cov khoom siv thiab kev thauj mus los. Cov hlau nthuav tawm zoo toughness thiab ductility, uas yog ib qho tseem ceeb rau daim ntawv thov raug rau dynamic loads.

Qhov zoo ntawm S690 Steel:
- Siab zog - rau - Qhov hnyav piv:Pab kom tsim cov qauv sib dua.
- Weldability zoo heev:Haum rau ntau yam txheej txheem vuam, yooj yim fabrication.
- Zoo Toughness:Tswj kev ua haujlwm hauv qhov chaw qis - qhov kub thiab txias.

Kev txwv ntawm S690 Steel:
- Tus nqi:Siab dua li cov qauv steels vim yog cov ntsiab lus alloying.
- Brittleness ntawm Tsawg Kub:Yuav tsum tau ua tib zoo xav hauv qhov chaw txias.
- Limited Corrosion Resistance:Tej zaum yuav xav tau cov txheej tiv thaiv nyob rau hauv ib puag ncig nruj.

S690 steel tau txais txiaj ntsig tseem ceeb hauv kev ua lag luam vim nws qhov kev ua tau zoo hauv kev tsim kho hnyav, tsuas, thiab kev siv sab nrauv. Nws cov keeb kwm tseem ceeb nyob rau hauv nws txoj kev loj hlob kom tau raws li qhov kev xav tau ntawm cov ntaub ntawv muaj zog dua thiab muaj txiaj ntsig zoo hauv kev tsim vaj tsev niaj hnub no.

• Tshuaj muaj pes tsawg leeg

• S690 steel yog cov pa roj carbon -manganese- molybdenum steel alloy uas muaj zog txhua yam thiab muaj zog zoo.

• Mechanical zog

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm S690 steel yog nws cov kev tiv thaiv rau cov neeg kho tshuab kev nyuaj siab. Cov khoom siv no tau tsim los tiv thaiv cov khoom hnyav thiab cov xwm txheej tsis zoo thiab yog li ntawd zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj zog thiab kev ntseeg tau.

• Hardness

S690 steel paub txog nws qhov siab hardness, uas ua rau nws zoo meej rau cov ntawv thov uas yuav tsum tau hnav thiab qaug zog tiv thaiv: tus yam ntxwv tseem ceeb hauv kev ua haujlwm uas xav tau heev, xws li mining.

• Corrosion kuj

S690 steel muaj kev tiv thaiv zoo heev rau cov neeg ua haujlwm hauv huab cua thiab cov xwm txheej hauv qhov chaw corrosive: nws yog, yog li ntawd, tsim nyog rau cov haujlwm uas xav tau kev ua haujlwm sab nraum zoov, xws li kev tsim khoom hauv nkoj thiab kev tsim kho vaj tse.

S690 steel yog siv rau ntau yam kev siv, suav nrog: kev tsim kho cov khoom siv kho tshuab (axles, txuas rods, zog, pinions, daim hlau), cov khoom siv tshuab (twj, li qub, bearings) thiab cov khoom siv rau cov thermo- hydraulic systems (pipes, fittings).

Yog li ntawd, muaj ntau ntau thiab txawv sectors nyob rau hauv uas nws yog dav siv:

Kev lag luam mining:S690 alloy structural steel phaj, ua tsaug rau nws cov neeg kho tshuab lub zog, hardness thiab hnav tsis kam, yog dav siv nyob rau hauv kev tsim cov khoom hnyav machinery Cheebtsam, xws li loaders los yog grinders.

Naval sector: Ua tsaug rau nws cov kev tiv thaiv corrosion thiab atmospheric cov neeg ua haujlwm, S690 steel yog thawj qhov kev xaiv rau kev tsim cov nkoj thiab nkoj nkoj.

Infrastructure:txuas hniav, piv txwv li, raug rau cov loads loj thiab qee zaum huab cua huab cua. S690 steel nrog nws peculiarities guarantees kev nyab xeeb thiab durability ntawm cov qauv nyob rau lub sij hawm.

Aerospace kev lag luam: hardness thiab lub zog ua ke nrog lub teeb ua kom cov hlau no yog cov khoom siv zoo tshaj plaws rau cov khoom siv hauv qhov tshwj xeeb no.

Zog sector: S690 steel pom daim ntawv thov nyob rau hauv cheeb tsam no ua tsaug rau nws lub peev xwm los tiv taus siab loads thiab huab cua.

Thaum xaiv S690 steel, yam xws li tus nqi, muaj, thiab cov ntawv thov tshwj xeeb yuav tsum raug txiav txim siab. Thaum nws muaj lub zog zoo dua, nws cov nqi siab dua thiab muaj peev xwm cov nyom hauv machining thiab corrosion kuj tuaj yeem cuam tshuam qhov kev txiav txim siab.
