Q310GNH maitai

He maha nga korero e kiia ana e te tohu tohu COR-TEN te rino me etahi wa ka tuhia ki waho i te tohuhono hei corten steel, he roopu koranu rino i hangaia hei whakakore i te hiahia ki te peita, me te hanga i te ahua waikura pumau mena ka kitea ki te rangi. mo etahi tau.
I whakawhiwhia e te COR-TEN taketake te tohu tohu A 242 (COR-TEN A) mai i te roopu paerewa a ASTM International. Ko nga tohu ASTM hou ake ko A 588 (COR-TEN B) me A 606 mo te pepa angiangi. Ko nga koranu katoa kei te hanga noa me te whakamahi.

Ka whakatauritea ki te waro maitai, he pai ake te parenga o te tira Q310GNH ki te hau. Ka whakatauritea ki te kowiri tira, he tohu noa nga huānga whakakotahi, a ko te tapeke o te ūkuikui, te parahi, te chromium, te nickel, te molybdenum, te niobium, te vanadium, te titanium, me era atu o nga koranu penei i te maitai huarere he iti noa iho.
