Hastelloy C-4
Whakaahuatanga Poto:
Hastelloy C-4 (UNS NO6455)
Tirohanga Whānui mō ngā Āhuatanga me ngā Taupānga o Hastelloy C-4:
He koranu nikara-molibdenum-chromium waro-iti te koranu austenitic. Ko te rerekētanga matua i waenga i te Nicrofer 6616 hMo me ētahi atu koranu o te hanganga matū rite i whakawhanakehia i mua ko te waro iti, te silicon, te rino me te tungsten. Ka whakaratohia e tēnei hanganga matū he pumau pai i te 650-1040 ° C me te ātete pai ake ki te waikura intergranular, ka karo i te ngoikore o te waikura raina taha me te waikura HAZ whakarewa i raro i ngā tikanga hanga tika. Koranu e whakamahia ana i roto i ngā pūnaha whakakorenga hau paru, te tipu whakapūkara me te whakaora waikawa, te hanga waikawa acetic me ngā matū ahuwhenua, te hanga titanium dioxide (tikanga chloride), te whakakikorua hiko.

Te mahi me ngā whakaritenga o te tukanga Hastelloy C-4:
1, I roto i te tukanga whakamahana, kaua e pā ki te whanariki, te whākōkī, te mata me ētahi atu konganuku iti te ira rewa, ki te kore ka pakarukaru te koranu, me āta tango atu i ngā peita tohu, ngā peita tohu pāmahana, ngā pene tae, ngā hinu whakahinuhinu, te wahie me ētahi atu paru. Ko te iti o te ihirangi whanariki o te wahie, ko te pai ake, me iti iho i te 0.1% te ihirangi whanariki o te hau maori, me iti iho i te 0.5% te ihirangi whanariki o te hinu taumaha. He pai ake te whiriwhiri i te whakamahana oumu hiko, nā te mea ka taea e te oumu hiko te whakahaere tika i te pāmahana, ā, he ma te hau oumu. Mēnā he parakore te hau o te oumu hau, ka taea e koe te whiriwhiri.
2, ko te whānuitanga pāmahana tukatuka wera o te koranu he 1080 ℃ ~ 900 ℃, ko te tikanga whakamatao he whakamatao wai, he whakamatao tere rānei. Hei whakarite i te ātete pai rawa atu ki te waikura, me whakahaere te maimoatanga wera i muri i te maimoatanga wera o te otinga.
