Q345GNH steel phaj yog siab- zog, qis- alloy, huab cua- cov hlau tsis muaj zog (tseem hu ua corten steel) uas ua tau raws li Suav tus qauv GB/T 4171. Nws yog alloyed nrog cov ntsiab lus xws li tooj liab, chromium, thiab npib tsib xee los tsim ib qho ruaj khov, tiv thaiv xeb txheej nyob rau sab nraum zoov, uas yuav tsum tau pleev xim rau. ntau daim ntawv thov. Qhov no ua rau nws tsim nyog rau kev tsim vaj tsev, txuas hniav, thiab kev siv zoo nkauj xws li facias.
