Lub zog cuam tshuam ntawm Q235 yog dab tsi?
A: Ntau tshaj lossis sib npaug rau 27J (V-notch) ntawm qhov ntsuas kub (B: 20 degree, C: 0 degree, D: -20 degree); A: Tsis xav tau Q235 weldable?
A: Weldability zoo heev (tsawg carbon sib npaug). Haum rau SMAW, GMAW, SAW; tsis xav tau preheat rau nyias seem.
Q235 puas tuaj yeem ua kom sov- kho?
A: Tsis yog rau kev txhim kho lub zog (tsawg carbon). Kev ntxhov siab -relief annealing (550–650 degree) yog qhov tshwm sim; hardening / quenching yog ineffective.
Dab tsi yog qhov ceev ntawm Q235?
A: ~ 7.85 g / cm³ (ib yam li cov hlau me me).
Lub melting point ntawm Q235 yog dab tsi?
A: ~ 1450-1500 degree.
