Q: Dab tsi yog cov khoom siv kho tshuab ntawm Q235 kauj?
A: Cov khoom tseem ceeb yog yield zog Ntau dua los yog sib npaug rau 235MPa, tensile zog 375 ~ 500MPa, thiab elongation Ntau dua los yog sib npaug rau 26% (rau thickness Tsawg dua los yog sib npaug rau 16mm).
Q: Dab tsi yog plasticity thiab toughness ntawm Q235 kauj?
A: Zoo plasticity, yooj yim rau stamp thiab khoov; Nyuaj toughness, Q235B / C / D qib tuaj yeem ua tau raws li qhov yuav tsum tau ua kom muaj zog ntawm qhov kub sib txawv.
Q: Dab tsi yog qhov weldability ntawm Q235 kauj?
A: Weldability zoo heev, tuaj yeem welded siv cov txheej txheem xws li arc vuam thiab roj vuam yam tsis muaj preheating, haum rau kev tsim cov khoom siv welded.
Q: Q235 kauj puas tuaj yeem ua kom sov- kho kom muaj zog?
A: Tsawg- carbon steel tsis muaj zog hardenability, thiab lub zog ntawm kev kho cua sov tsis pom tseeb. Feem ntau, nws tsis yog siv los txhim kho lub zog los ntawm kev kho cua sov, thiab feem ntau yog siv ncaj qha rau hauv kub -rolled xeev.
Q: Dab tsi yog qhov corrosion kuj ntawm Q235 kauj?
A: Nws corrosion kuj yog nruab nrab. Nws yooj yim rau xeb hauv qhov chaw ntub thiab yuav tsum tau txhim kho los ntawm kev pleev xim, galvanizing, lossis lwm txoj hauv kev.
