Dab tsi yog cov xeev kev xa khoom?
A: Kub dov (HR), uas yog dov (AR), tswj dov, normalized (N).
12. Puas yog Q235 weldable?
A: Weldability zoo heevvimcov pa roj carbon tsawg. Haum rau arc, roj, tsis kam vuam.
13. Puas yog Q235 zoo rau khoov?
A: Zoo txias formability/bendability. High ductility (Ntau dua lossis sib npaug ntawm 26% elongation) txo qhov tawg.
14. Q235's corrosion kuj yog dab tsi?
A: Tsis zoo corrosion kuj(rusts yooj yim). Yuav tsum tau pleev xim, galvanizing, lossis lwm yam txheej.
15. Q235 puas tuaj yeem kho cua sov?
A: Feem ntautsis hardened los ntawm quenching(tsawg carbon). Sivraws li -rolled; normalization tuaj yeem txhim kho uniformity.
