Q310GNH uamea

e masani ona taʻua e le genericized trademark COR-TEN sila ma o nisi taimi e tusia e aunoa ma le hyphen e pei o le corten steel, o se vaega o uʻamea uʻamea lea na atiina ae e aveesea ai le manaomia o le valiina, ma fausia ai se foliga ele tumau pe a faʻaalia i le tau. mo ni nai tausaga.
O le uluai COR-TEN na maua le fa'ailoga masani A 242 (COR-TEN A) mai le ASTM International standards group. O togi fou a le ASTM o le A 588 (COR-TEN B) ma le A 606 mo pepa manifinifi. O alofi uma o loʻo tutusa le gaosiga ma le faʻaaogaina.

Pe a faatusatusa i le uamea carbon, Q310GNH uamea e sili atu le tetee corrosion i le siosiomaga. Pe a faatusatusa i uʻamea uʻamea, o loʻo i ai naʻo elemene faʻafefiloi, ma o le aofaʻi o phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, ma isi mea faʻapipiʻi e pei o le weathering steel e na o ni nai pasene.
