EN 10210 S235 BU235 HLAU QIB

En 10210qhia meej txog qhov yuav tsum muaj rauKub-tiav Cov Qauv Hollow(ncig, square, thiab duab plaub) ua los ntawmTsis-Alloy thiab Zoo-Grain SteelsCov. TusS235Cov yim neeg muaj ntau cov qhab nia nrog txawv cov kev cuam tshuam nyuaj, tsim rau ib puag ncig ib puag ncig.

Cov lus qhia no tsom rau peb qhov tseem ceeb tshaj plaws:

S235jrh(Cov qauv cuam tshuam kuj, chav sov)

S235J0H(txhim kho kev tawv ntawm 0 degree)

S235J2H(Txhim Kho Kev nyuaj ntawm -20 degree)

Tus"H"SALIX qhia tau tias cov hlau tau muab rau hauvKub-ua tiavmob.

Cov txheej:Cov xim dub, kua roj vanish, tiv thaiv cov roj xeb.
Cov Ntawv Thov:Cov cuab yeej ua liaj ua teb, cov qauv kws kos duab, kev tsim cov moj khaum rau choj thiab cov tuam tsev, khoom siv tshuab ua khoom siv.

• Carbon (c): Cov ntsiab lus carbon hauv s235 steel yog feem ntau txwv rau qee qhov ntau, feem ntau yog nyob ib ncig}. 17} {3}}. 22%. Cov pa roj carbon yog ib qho tseem ceeb heev uas cuam tshuam lub zog thiab hardness ntawm cov hlau. Ib qho cov ntsiab lus tsawg dua hauv S235 pab kom tswj kom muaj weldability zoo thiab ductility.
• Silicon (si): Cov ntsiab lus silicon yog tsis muaj kev xav tau tshwj xeeb. Silicon tau ntxiv los txhim kho lub zog thiab deoxidation ntawm cov hlau. Nws kuj tseem yuav pab txhawb kom cov tsis kam mus rau oxidation thiab txhim kho cov khoom siv thev naus laus zis tag nrho.
• Manganese (mn): Cov ntsiab lus manganese hauv s235 steel yog feem ntau tsis muaj ntau tshaj 1.40%. Manganese txhim kho lub hardenability thiab lub zog ntawm cov hlau. Nws kuj tseem pab kom txo cov kev phom sij ntawm cov neeg SULFUR, txhim kho qhov zoo thiab tawv ntawm cov hlau.
• Phosphorus (p)thiabSulphur (s): Cov ntsiab lus phosphorus feem ntau yog txwv tsis pub tshaj li {{0}}}}}}}}. 04%}. 04%}. 04%}. Cov ntsiab lus no yuav tsum tau tswj hwm nyob rau hauv ntau yam kom tsis txhob embrittlement thiab txhim kho qhov zoo thiab ductility ntawm cov hlau.

• Qhov sib txawv tseem ceeb:

S235jrh: Cov ntawv thov kub (chav sov sov).

S235J0H: Haum rau0 degreeib puag ncig (piv txwv li, cheeb tsam txias).

S235J2H: Rau-20 degreeCov xwm txheej (Arctic Clourates, Offshore qauv qauv).

Kub-Tiav Ntau Lawm: Seamless lossis welded hollow cov ntu tsim thaum kub.

Kev Kho Cua Sov: Yuav siv los txhim kho kev nruj (tshwj xeeb tshaj yog rau J2H).

Hwj txwv: Zoo heev (qis CEV tso cai rau yooj yim vuam tsis muaj preheating feem ntau).

•  Vim li cas thiaj xaiv S235?

Zoo dua tawv (tseem ceeb rau kev thauj khoom zoo).
Ntau cov khoom siv tshuab hluav taws xob.
Nyiam rau welded qauv nyob rau hauv ib puag ncig txias.

• S235jrh: Qib qib rau kev tsim kho dav dav.
• S235J0H: Zoo dua rau0 degreeib puag ncig.
• S235J2H: Zoo tshaj plaws rau-20 degreetej yam kev mob.

Hauv cov ntsiab lus, qhov EN 10210 S235 Steel menyuam (Kub-ua tiav s235 hollow ntu ntu, muab ntau txoj kev xaiv rau cov ntawv thov sib txawv raws lawv cov kev cuam tshuam tshwj xeeb tsis kam thiab microstructure cov yam ntxwv. Cov kawm qib no yog lub luag haujlwm tseem ceeb hauv kev tsim kho thiab kev tsim kho tshuab, kev txhim khu kev qha enjection rau ntau yam qauv thiab kev siv tshuab.
