Qhov sib txawv:
- S355J0H: Sim ntawm0 degree(Haum rau kev hloov pauv huab cua txias).
- S355J2H: Sim ntawm-20 degree(zoo dua rau cov ntawv thov tsawg-).
Cov ntawv thov thiabQhov Zoo
Cov Ntawv Thov
Ob chav kawm tau siv nyob rau hauvThauj-cov kabmob qauvQhov twg muaj zog thiab tawv yuav tsum:
- S355J0H:
Vaj tse, txuas hniav, kev tsim kho dav dav (cov kabmob uas yuav tsum muaj kev cuam tshuam rau qhov kub thiab qhov ntsuas kub.
- S355J2H:
Offshore qauv, kev tsim tawm tsam lub caij ntuj no, xav tau kev ua haujlwm nyob rau hauv ib puag ncig hnyav nrog tsis tshua muaj kub thiab siab - cuam tshuam loads.).
Qhov Zoo
- Siab Zog Thiab Deev: Kev sib xyaw ua ke ntawm cov nyiaj muaj txiaj ntsig zoo thiab txaus ua kom muaj txiaj ntsig zoo rau S355 hlau siv rau hauv cov ntawv thov txheej txheem. Nws tuaj yeem txhawb nqa cov khoom hnyav thaum tseem tuaj yeem mus rau qee qhov deformation yam tsis muaj av qeeg.
- Zoo Weldability: S355 steel muaj qhov zoo weldability, uas txhais tau tias nws tuaj yeem tuaj yeem koom nrog lwm cov hlau siv ntau cov txheej txheem. Qhov no yog qhov tseem ceeb rau kev tsim kho cov qauv txheej txheem nyuaj.
- Zoo ib yam zoo: En 10219 cov qauv ua kom ntseeg tau tias cov ntu hollow ua los ntawm S355 Steel tau ua tiav cov cai nruj. Qhov xwm txheej zoo sib xws yog qhov tseem ceeb rau kev ntseeg tau thiab kev nyab xeeb ntawm cov qauv tsim nrog cov khoom no.
Kev tsim khoom & kev ua
Txias-tsim hollow tshooj(Welded leeg, profiles).
Hwj txwv: Zoo heev (preheating feem ntau tsis tas yuav tsum muaj rau cov ntu nyias).
Muaj meej: Zoo rau khoov thiab machining.
