1. Vim li cas Q235 steel siv dav hauv kev tsim kho?
Q235 steel yog alow-carbon, tsis yog- alloy structural steeluas muab ib tug zoo tshuav ntawmlub zog, ductility, thiab weldabilityntawm tus nqi pheej yig. Nws cov khoom ua rau nws haum rautxuas hniav, factories, warehouses, shipbuilding, thiab kev siv cov txheej txheem, tshwj xeeb tshaj yog qhov hnyav hnyav tsis tas yuav tsum tau ua.
2. Qhov "B" hauv Q235B txhais li cas?
Tsab ntawv qhia txog qhovcuam tshuam ntsuas kub rau toughness.
Q235B yog kuaj ntawm+20 degree, ua rau nws haum rau qhov kub thiab txias ib puag ncig.
Lwm cov qib, xws li C thiab D, raug kuaj ntawm 0℃thiab -20℃raws li, rau kev siv huab cua txias -. Qib cuam tshuamcuam tshuam toughness, thaum tag nrho lub zog thiab weldability tseem zoo ib yam.
