Q: Dab tsi yog daim ntawv thov tseem ceeb ntawm Q235 kauj?
A: Siv dav hauv kev tsim kho engineering (steel structures, supports, guardrails), machinery manufacturing (agricultural machinery parts, equipment bases), automotive industry (chassis, body panels), home appliance manufacturing (casings, support), and pipeline manufacturing.
Q: Qhov twg yog qhov tsim nyog rau kev tsim cov khoom hauv qis - qhov kub thiab txias, Q235A kauj lossis Q235B kauj?
A: Q235B kauj yog qhov tsim nyog dua vim tias Q235B yuav tsum tau kuaj xyuas qhov kub thiab txias dua li Q235A, uas tsis raug kuaj xyuas.
Q: Q235 puas tuaj yeem siv los tsim cov hlab ntsha siab?
A: Tsis yog, cov hlab ntsha siab yuav tsum muaj lub siab lub nkoj steel (xws li Q345R). Lub zog thiab tawv ntawm Q235 tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Q: Dab tsi yuav tsum tau ceev faj thaum siv Q235 coil hauv cov qauv hlau?
A: Cov qib zoo yuav tsum raug xaiv raws li qhov chaw ua haujlwm. Q235C/D yog qhov zoo dua rau qhov qis- qhov kub thiab txias. Nto oxide nplai yuav tsum tau muab tshem tawm ua ntej vuam kom tsis txhob cuam tshuam qhov zoo ntawm vuam.
Q: Dab tsi yog stamping kev ua tau zoo ntawm Q235 kauj? Dab tsi ntawm stamped qhov chaw nws haum rau?
A: Nws muaj kev ua haujlwm zoo stamping thiab tsim nyog rau kev ua haujlwm ntiav -stamped qhov chaw (xws li cov tais, cov hlua yooj yim). Rau qhov sib sib zog nqus- stamped qhov chaw, nws raug nquahu kom siv txias- dov qis- carbon steel (xws li SPCC).
