Hastelloy C-4
Whakaahuatanga Poto:
Hastelloy C-4 (UNS NO6455)
Hastelloy C-4 Ahuatanga me nga tono Tirohanga:
Ko te koranu he austenitic iti-carbon nickel-molybdenum-chromium alloy. Ko te rereketanga nui i waenga i te Nicrofer 6616 hMo me etahi atu koranu o te hanganga matū rite i whakawhanakehia i mua ko te waro iti, te silicon, te rino me te tungsten. Ko tenei hanganga matū e tino pai ana ki te 650-1040 ° C me te pai ake o te aukati ki te waikura intergranular, te karo i te whakaraeraetanga o te waikura o te taha o te raina me te wea i te waikura HAZ i raro i nga tikanga hangahanga tika. Ko te whakakotahitanga i whakamahia i roto i nga punaha whakaheke hau rewharewha, te tipu me te tipu whakaora waikawa, te waikawa acetic me te hanga matū ahuwhenua, te hanga titanium dioxide (tikanga pūhaumāota), te whakakikorua hiko.

Hastelloy C-4 mahi tukanga me nga whakaritenga:
1, I roto i te tukanga maimoatanga wera e kore e taea te whakapā atu ki te whanariki, ūkuikui, mata me etahi atu whakarewa iti rewa, ranei ka riro pakarukaru te koranu, kia aro ki te tango pērā i te tohu peita, peita tohu pāmahana, pene kara, lubricants, wahie me etahi atu paru. Ko te iti o te whanariki o te wahie ka pai ake, ko te whanariki o te hau maori kia iti iho i te 0.1%, ko te whanariki o te hinu taumaha kia iti iho i te 0.5%. Ko te whakamahana o te oumu hiko he pai ake te whiriwhiri, na te mea ka taea e te oumu hiko te whakahaere tika i te pāmahana me te maemaa o te hau. Mena he tino parakore te oumu hau, ka taea e koe te whiriwhiri.
2, koranu waiariki tukatuka awhe pāmahana o 1080 ℃ ~ 900 ℃, tikanga tautauā mo te wai mātao atu meangiti tere ranei. Hei whakarite i te pai o te waikura, me whakahaere te maimoatanga wera i muri i te maimoatanga wera otinga.
