INCONEL® koranu 690(UNS N06690/W. Nr. 2.4642) he koranu nickel teitei-chromium he tino pai te atete ki te maha o nga papaaho wai whakakino me nga hau-mahana teitei.I tua atu i tona parenga waikura, ko te koranu 690 he kaha teitei, he pai te pumau o te whakarewa, me nga ahuatanga hanga pai.
Ko te Inconel Alloy 690 Pipe & Tube he tino parenga nui ki te whanuitanga o nga purongo kino pera i te pakaru o te ahotea katote pūhaumāota tae atu ki te tuku mahi teitei o te pāmahana me te aukati i te waikura.
Ko te Inconel Alloy 690 Pipe & Tube he austenite nickel-chromium-based superalloys grades ngongo, ngongo, putorino me nga hua ngongo ki te Hinu Me te Hau, karihi Me te Hiko, Whakangao Hiko, Aerospace, Ahumahi Tukatuka me te Whakapai, Ahumahi Ahumahi, Tukatuka Matū, Hauora. , Te Maamaa Teitei me te Mahi Nui.Ko te Inconel Alloy 690 Pipe & Tube e pai ana mo te mahi i roto i nga taiao tino kaha ki te pehanga me te wera.

Te Whakawera me te Piki
Pērā i ētahi atu koranu nickel, ko te koranu 690 kia ma i mua i te whakamahana me te whakamahana i roto i te hau whanariki iti.Ko nga hau o te oumu mo te whakamahana tuwhera me whakaiti hoki kia kore ai e nui te waikura o te rauemi.
Ko te koranu INCONEL 690 he koranu wairewa totoka me te kore e whakapakeketia e te maimoatanga wera.I te nuinga o te wa ka whakamahia te koranu i roto i te ahua o te reera.
Te hanga
Ko te awhe pāmahana mo te hanga wera nui o INCONEL koranu 690 he 1900 ki te 2250°F (1040 ki te 1230°C).Ka taea te hanga marama i te mahana ki raro ki te 1600°F (870°C).
Hangangaiti
Ko te koranu INCONEL 690 he koranu austenitic, whakarewa-toka me te teitei o te whakapumautanga whakarewa.He iti te whakarewatanga o te koranu mo te waro, me te tikanga kei roto i te hangahanga moroiti nga carbide.Ko te carbide nui kei roto i te koranu ko M23C6;he rereke te nui o te wahanga ki te ihirangi waro me te whakamaarama wera o te rauemi.Ko etahi atu waahanga ko te titanium nitrides me te carbonitrides.Karekau he wahanga whakakorikori whakakorikori penei i te wahanga sigma i kitea i roto i te koranu 690.
