Mtengo wa Q310GNH

Zomwe nthawi zambiri zimatchulidwa ndi chizindikiro cha genericized trademark COR-TEN zitsulo ndipo nthawi zina zolembedwa popanda hyphen ngati chitsulo cha corten, ndi gulu lazitsulo zazitsulo zomwe zinapangidwa kuti zithetse kufunikira kojambula, ndikupanga mawonekedwe okhazikika ngati dzimbiri ngati akumana ndi nyengo. kwa zaka zingapo.
COR-TEN yoyambirira idalandira dzina lodziwika bwino la A 242 (COR-TEN A) kuchokera ku gulu la ASTM International. Magiredi atsopano a ASTM ndi A 588 (COR-TEN B) ndi A 606 a pepala lopyapyala. Ma alloys onse ndi ofanana kupanga ndikugwiritsa ntchito.

Poyerekeza ndi chitsulo cha carbon, Q310GNH chitsulo chimakhala ndi kukana bwino kwa dzimbiri mumlengalenga. Poyerekeza ndi zitsulo zosapanga dzimbiri, pali zinthu zina zomwe zimapangidwira, ndipo phosphorous, mkuwa, chromium, faifi tambala, molybdenum, niobium, vanadium, titaniyamu, etc.
