Q310GNH Icyuma

bikunze kuvugwa nikirangantego rusange COR-TEN ibyuma kandi rimwe na rimwe byandikwa nta hyphen nkicyuma cya corten, ni itsinda ryibyuma bivangwa nicyuma byakozwe kugirango bikureho amarangi, kandi bigaragaze isura ihamye isa ningese iyo ihuye nikirere imyaka myinshi.
Umwimerere COR-TEN yakiriye izina risanzwe A 242 (COR-TEN A) kuva mu itsinda mpuzamahanga rya ASTM. Amanota mashya ya ASTM ni A 588 (COR-TEN B) na A 606 kumpapuro zoroshye. Amavuta yose ari mubikorwa bisanzwe kandi bikoreshwa.

Ugereranije nicyuma cya karubone, ibyuma bya Q310GNH bifite imbaraga zo kurwanya ruswa mu kirere. Ugereranije nicyuma kitagira umwanda, hariho ibintu bivangavanze gusa, kandi fosifore yose, umuringa, chromium, nikel, molybdenum, niobium, vanadium, titanium, nibindi byamavuta nkibyuma byikirere ni bike ku ijana.
