** {1. Cov khoom siv yog s235jr yeeb nkab ua los ntawm? **
S235jr yeeb nkab yog ua los ntawm ** cov txheej txheem tsis yog-alula} Nws muaj tsawg kawg yog kev tsim kho ntawm lub zog rau nws qhov chaw zoo weldability thiab Formarity .
** {2. Dab tsi yog cov khoom ntawm s235jrh hlau? **
S235Jrh yog ** txias-tsim Welded Hollow qauv hlau ** (en} . nws muaj cov khoom muaj xws li:
- Yam tsawg kawg nkaus paib lub zog: ** 235 mpa **
- Zoo ** Weldability ** thiab ** Ductility **
- Kev cuam tshuam cov kev ntsuas nruj ntawm ** {0℃** ("H" ntawm cov ntu Hollow, tsis yog ntsuas kub) {2}
- Cov ntsiab lus carbon qis (tsawg dua los yog sib npaug rau 0 {. 17%) thiab tswj cov sulfur cov qib / phosphorus theem rau kev txhim kho durabiled durabiled durability.
** {3. Yuav ua li cas peb hom hlau kav? **
Peb hom phiaj xwm qib siab raws li kev tsim qauv yog:
- ** SEAMLESS PIPES **: Ua los ntawm extruding khoom billets, siv rau cov ntawv thov siab siab.
- ** WELDED PIPES **: Tsim los ntawm Rolling Hlau Co thiab Vuam Seams (Subtypes suav nrog ERW, LSAWW, thiab SSAW).
- ** galvanized kav dej **: Coated nrog zinc kom tiv taus corrosion, feem ntau siv nyob rau hauv cov kav dej thiab sab nraum zoov kev.
** {{4. Dab tsi yog tus qauv s355 yeeb nkab? **
S355 kav ua raws li ** en 10210-1 (kub-formed) **} (txias}}} Cov Nta Cov Nta suav nrog:
- Yam tsawg kawg nkaus paib lub zog: ** 355 mpa **
- Txhim kho kev nruj thiab weldability .
- Rho tawm zoo li S355j2h lossis S355K2h lossis S355K2H, qhia txog kev cuam tshuam kub (E {}}}}}℃rau j2) {9} {9}
** {5. Dab tsi yog S355 qib steel? **
S355 yog ** High-zog qes-alloy (HSLA) cov hlau txheem steel ** nrog tsawg kawg lub zog ntawm 355 mpa {4} nws muaj:
- Cov khoom siv zoo tshaj piv rau qhov s235.
- Txhim kho kev nyuaj ntawm tsawg kub (cov khoom sib cais zoo li S355j2, S355K2) .
- Cov ntawv thov hauv hnyav-load txheej txheem (txuas hniav, cranes) thiab cov khoom siv yuav tsum muaj kev ntxhov siab tiv thaiv kev ntxhov siab txog kev ntxhov siab.
- Kev muaj pes tsawg leeg suav nrog cov pa roj carbon, manganese, thiab microalloying ntsiab (e. patadium, vanadium, vanadium, vanadium) rau lub zog {}}
