Kua tohua hei UNS N08825, DIN W.Nr ranei. 2.4858, Incoloy 825 (e mohiotia ana ko "Alloy 825") he koranu rino-nickel-chromium me nga taapiri molybdenum, cooper me te titanium. Ko te taapiri molybdenum ka whakapai ake i tana atete ki te pitting i te waikura i roto i te tono waikura wai i te mea ko te ihirangi parahi ka whakaahuru ki te waikawa pungatara. Ka taapirihia te Titanium mo te whakapumau. He tino pai te Alloy 825 ki nga waikawa whakaheke me te waikura, ki te pakaru o te ahotea-waikura, me te whakaeke i te rohe penei i te rua me te waikura kapiti. He tino ātete ki te waikawa pungatara me te waikawa phosphoric. Ko te koranu Incoloy 825 te nuinga e whakamahia ana mo te tukatuka matū, te paipa petrochemical, nga taputapu whakahaere parahanga, te paipa paipa hinu me te hau, te tukatuka hinu karihi, te hanga waikawa, me nga taputapu pika.
