Q: Dab tsi yog lub zog tawm los, lub zog tensile, thiab elongation tsis ntawm Q235?
A: Yield zog Ntau dua lossis sib npaug rau 235 MPa; tensile zog 375 ~ 500 MPa; elongation Ntau dua lossis sib npaug li 26% (thickness Tsawg dua lossis sib npaug li 16 hli).
Q: Vim li cas Q235 thiaj li tsim nyog rau kev tsim vaj tsev?
A: Zoo plasticity, zoo heev weldability, ua haujlwm txias ua haujlwm zoo, tsis tshua muaj nqi, thiab tuaj yeem ua tau raws li cov qauv zoo li qub thiab cov khoom siv dynamic load.
Q: Dab tsi yog qhov weldability ntawm Q235? Cov txheej txheem vuam zoo li cas?
A: Weldability zoo heev, weld zog ze rau ntawm cov khoom siv. Haum rau cov txheej txheem ib txwm muaj xws li arc vuam, argon arc vuam, thiab CO₂ gas shielded vuam, tsis nyuaj preheating / ncej- cua sov.
Q: Dab tsi yog kev ceev faj rau kev ua haujlwm txias thiab kub ntawm Q235?
A: Kev ua haujlwm txias tso cai rau dov, khoov, thiab stamping, tab sis ntau dhau deformation tuaj yeem ua rau muaj hnub nyoog tawv; kub ua hauj lwm yuav tsum tau nqa tawm ntawm 800 ~ 1000℃kom tsis txhob overheating los yog hlawv.
Q: Dab tsi yog qhov elastic modulus thiab ntom ntawm Q235?
A: Lub elastic modulus yog kwv yees li 206 GPa; Qhov ceev yog 7.85 g / cm³, raws li cov pa roj carbon zoo tib yam.
