Txheej Txheem Kev Ua Haujlwm
Txheej Txheem Kev Ua Haujlwm
-
Weldability zoo: Haum rau SMAW, SAW, GMAW, FCAW
-
Zoo formability: dabtsi yog khoov, txiav, xuas nrig ntaus, thiab machining
-
Zoo chav-kub toughness rau dynamic loading tej yam kev mob
- Qhov zoo: siab zog, siab toughness, zoo heev weldability, thiab tus nqi siab -effectiveness; qhov kev xaiv zoo tshaj plaws rau hnyav- cov ntawv thov kev ua haujlwm.
- Siv tau qhov kub thiab txias: Ib puag ncig saum toj no +20℃; rau qis- qhov kub thiab txias (tsawg dua lossis sib npaug li 0 degree), S355J0/J2 yog qhov kev xaiv zoo tshaj.
- Piv rau S235/S275: Muab lub zog ntau dua, ua rau nws tsim nyog rau cov xwm txheej uas muaj cov khoom hnyav, qhov loj me, thiab cov khoom hnyav.
