Ko te nui o te nickel content e homai ana i te koranu whai hua te ahotea i te aukati pakaru.
He pai te parenga waikura i roto i te maha o nga momo paoho, penei i te sulfuric, phosphoric, nitric me te waikawa waro, nga konganuku kawakore penei i te konutai waikawa, te konutai waikawa me te wairewa waikawa waikawa.
Ko te teitei ake o te mahinga o Incoloy 825 e whakaatuhia ana i roto i te whakakoi ngingiha karihi me te maha o nga momo paoho kino, penei i te waikawa pungatara, te waikawa nitric me te konutai waikawa, he mea tukatuka katoa i roto i te taputapu kotahi.

825 koranu ko te ahua o te koranu engineering whānui, e whai te waikawa me te alkali waikura ātete i roto i te hāoratanga me te whakaiti i te taiao me te ātete whai hua ki te ahotea te pakaruhanga waikura mo tona hanganga nickel teitei. I roto i nga momo pāpāho katoa, he tino pai te parenga waikura penei i te sulfuric. te waikawa, te waikawa phosphoric, te waikawa nitric me te waikawa waro, ki te kawakore, penei i te konutai hvdroxide, te konutai hvdroxide me te otinga waikawa hvdrochloric.Ko nga mahinga matawhānui teitei ake o te 825 koranu e whakaatu ana i roto i te whakarewatanga o te wera karihi o nga momo waikura, penei i te waikawa pungatara, te waikawa nitric me te konutai hvdroxide kei te whakahaere katoa i roto i te taputapu kotahi.
