Q: Dab tsi yog txoj kev txiav rau Q235 steel daim hlau?
A: Cov txheej txheem txiav feem ntau suav nrog nplaim taws, txiav ntshav, txiav laser, thiab shearing. Txawv thicknesses yuav tsum sib txawv txoj kev txiav.
Q: Dab tsi yog cov thickness ntau ntawm Q235 steel phaj?
A: Kub- dov Q235 steel phaj feem ntau nyob rau hauv thickness ntawm 3 mus rau 200 hli. nyias daim hlau (<3 mm) are mostly cold-rolled or hot-rolled thin plates.
Q: Dab tsi yog daim ntawv thov tseem ceeb ntawm Q235 steel phaj?
A: Siv dav hauv kev tsim vaj tsev (xws li cov kab hlau thiab cov kab), engineering machinery (xws li cov khoom siv hauv paus), cov khoom siv tsheb, ntim, choj railings, thiab cov khoom siv dav dav.
Q: Q235 steel daim hlau puas tuaj yeem siv los tsim cov hlab ntsha siab?
A: Tsis yog, cov hlab ntsha siab yuav tsum tau tshwj xeeb siab lub nkoj hlau (xws li Q345R). Q235's toughness thiab qaug zog tsis ua raws li qhov yuav tsum tau ua.
Q: Dab tsi yog qhov kev txwv ntawm kev siv Q235 steel phaj hauv qis- qhov kub thiab txias?
A: Q235A / B tsis haum rau qis -kub (<0℃) environments. For low-temperature environments, Q235C/D grade or higher performance low alloy steel plates should be selected.
