Cov yeeb nkab steel en 10219 S235JRH

EN 10219 S235JRH yog txias txias {2} Taug kev cov qauv welded, ua raws li cov qauv welded, hauv qab no yog cov ncauj lus kom ntxaws ntawm nws cov qauv:

Tshuaj lom neeg muaj pes tsawg leeg (cov kev txwv ntawm cov ntsiab lus tseem ceeb):

• Cov pa roj carbon (c): tsawg dua los yog sib npaug rau 0.20%
• Manganese (MN): 0.60% - 0.90%
• Silicon (si), phosphorus (p), leej faj (sau cov ntsiab lus txwv tsis pub dhau los (p tsawg dua lossis sib npaug lossis sib npaug 0.035%).Tsawg -} Carbon tsim ua kom zoo weldability thiab cov yas, thiab manganese txhim kho lub zog.

Cov Khoom Siv Neeg Kho Tshuab:

• Yield zog (RP0.2): Ntau dua lossis sib npaug rau 235 MPa
• Tensile Lub Zog (RM): 340-480 MPA
• Elongation (a): ntau dua lossis sib npaug rau 23%High elongation qhia tau zoo heev zoo ntawm cov khoom thiab yog haum rau cov xwm txheej uas xav tau khoov lossis cuam tshuam.

Ntu hom thiab ntau yam:

• Hloov yeeb nkab hluav taws xob: cov uas hla 88.9-2540mm (phab ntsa tuab 2.5-25.4mm)
• Square Hmes (Shs): Sab ntev 20-800 hli (Phab Ntsa Thickness 2-30 hli)
• Cov leeg plaub hau (RHS): NTUJ SABER 20-750mm, Side Luv 20-500mm.Cov kev qhia tshwj xeeb muaj xws li 50 × 50 × 3-5mm square dres, uas yog siv rau lub teeb yuag.

Yuav Tsum Tau Yuav Tsum:

Sab ntev ntev: ± 1.5mm

Phab Ntsa Thickness kam Zam: ± 10% tNws txias txoj kev tsim cov txheej txheem ua kom cov qhov raug thiab yog qhov haum rau cov sib dhos ua kom meej.

Txheej txheem tsim khoom:

• Dabtsi yog khoov ua ke: Cov phaj steel yog khoov ntawm chav tsev kub thiab tom qab ntawd tsim los ntawm high- cov khoom siv arc vuam (pom).
• Tsis muaj kev kho cua sov: tsis muaj kev kho cua sov yog nqa tawm tom qab vuam, khaws cov khaub thuas txias ua haujlwm (kev ntxhov siab ntau, tab sis muaj kev ntxhov siab ntau dua).
• Cov kev kho deg: galvanizing (anti - corrosion) lossis kev ua si dub (tsim cov olidide txheej los tiv thaiv corrosion) muaj.

Soj Ntsuam Zoo:

• Kev ntsuam xyuas txhua lub zog: Tensile thiab kev ntsuas rau txhua pob (kev cuam tshuam Toughness ntawm -20℃yuav tsum ua kom tau raws tus qauv).
• Tsis - Kev Kuaj (NDT): 100% Ultrasonic / scoraptapic Testing ntawm Weld Seams.
• Kev Kuaj Dej Siab: tswj hwm rau ntau tshaj 5 vib nas this, thiab lub siab yog xam raws tus qauv.

• Tsev qauv: siab {{{{}} sawv thav duab, cov kab ntawv pab txhawb nqa, lub ru tsev trusses (siab qhov tseeb.
• Mechanical manufacturing: convening cov khoom nkhaus, crane booms (Weldability zoo yuav tsum tau).
• Lub nroog Engineering: Txoj Kev Goldenrails, Choj istanized qauv (galvanized anti - corrosion version).
• Lwm hom teb: Rooj tog hauv rooj tog (kev tsim qauv tsim), photovoltaic nkhaus, billboards.

Siv Tau Txoj Kev Xaiv:

• Pom zoo rau 10219 S235JRH: Feem ntau rau cov khoom siv zoo li qub (xws li lub tsev txhawb), nqi {{{}}}}}} sensitive sensitive sensitive sensitive sensitive sensitive sensitive} sensitive sensitive sensitive sensitive sensitive sensitive..
• Unsuitable scenarios: High impact loads (such as crane main beams) or high-temperature environments (>350 degree), nyob rau hauv cov ntaub ntawv uas cov thermoforming qauv en 10210 (xws li S355j2H) yuav tsum tau xaiv.

Daim ntawv pov thawj CE yuav tsum muaj:

• Kev ua pov thawj yuav tsum xa tawm rau EU yuav tsum ua raws li kev cai CPR (EU 305/2011).
• Cov ntsiab lus uas tau muaj ntawv pov thawj:

1. Pib hom tshuaj ntsuam (ITT): Cov cuab yeej siv rau neeg kho tshuab thiab cuam tshuam cov kev ntsuas nruj.
2. Lub Hoobkas tsim kev tswj hwm (FPC): Tag nrho - txheej txheem kev tshuaj xyuas qhov system zoo.

• Cim kev pab: Tom qab ntawv pov thawj, CE CE cim yuav ua tau thiab kev tshaj tawm kev ua haujlwm (DOP) tuaj yeem muab.

Tu thiab tukeep

• Tsis tu ncua txheeb xyuas rau saum npoo xeb. Nws raug nquahu kom thov anti - corrosion xim (xws li} funch nplua nuj) hauv qhib- huab cua ib puag ncig.
• Zam kev ua haujlwm ntau dhau los tiv thaiv cov khoom tawg yas.

En 10219 S235JRH, nrog nws cov kev ntsuas siab, zoo weldability thiab tus nqi- qhov kev xaiv zoo rau cov kev siv zoo li qub. Txawm li cas los xij, nws yuav tsum tau sau tseg tias nws cov kev ntxhov siab uas muaj kev ntxhov siab kuj tseem ceeb thiab nws tsis haum rau cov xwm txheej dynamic loadarios. Thaum xaiv hom, cov kev tsim kho tshuab ua haujlwm yuav tsum tau coj mus rau hauv tus account. Cov peev xwm thiab cov ntaub ntawv pov thawj ntawm cov neeg xa khoom yuav tsum nruj me ntsis saib xyuas, thiab kev txij nkawm tsis tu ncua yuav tsum tau ua lub neej pabcuam.
