Ngā Painga Matua o Incoloy 825
Ātete Waikawa Tino Pai– Ka whakarato a Incoloy 825 i te ātete tino pai ki ngā waikawa whanariki, phosphoric, me te hauota puta noa i te whānuitanga o te kukū me te awhe pāmahana. Mā te whakakotahitanga o te nikara, te chromium, te molybdenum, me te parahi ka hangaia he rauemi e ātete ana ki ngā taiao waikawa whakaiti me te waikura. I roto i te waikawa whanariki tae atu ki te 40% te kukū i te 100°C, he iti iho i te 0.5 mm/tau te tere waikura.
Ātete ki te Waikura me te Poka– Ko te nui o te molybdenum (2.5-3.5%) e whakarato ana i te ātete tino pai ki te waikura o te poka me te kapiti i roto i ngā taiao kei roto he pūhaumāota. Ko te uara PREN o te 36 pea e whakarite ana i te mahi pono i roto i ngā awa wai me ngā awa tukatuka whai pūhaumāota i te wā e pakaru ai te maitai kore waikura 316L.
Ātete ki te pakaru o te waikura– Ko te nui o te nikara (38-46%) e whakarato ana i te ātete tino pai ki te pakaru waikura i puta mai i te hauota. He tino ātete a Incoloy 825 ki te SCC i roto i te wai moana, te rehu tote, me ngā taiao kei roto te hauota kei reira ngā maitai kore waikura 304/316 e pakaru pinepine ana.
Whakapūmautanga o te Titanium– Mā te tāpiritanga o te titanium (0.6-1.2%) ka whakau i te koranu ki te waikura ā-ira. Mā te hanga i ngā putunga TiC me TiN pumau, ka ārai te titanium i te hanganga o ngā warowaiha chromium i ngā rohe kōpaka i te wā e whakarewahia ana, ka whakarite kia ātete ki te waikura i te rohe e pāngia ana e te wera.
He Āheitanga Whakarewa Pai rawa atu– Ka taea te whakarewa i te Incoloy 825 mā te whakamahi i te TIG, MIG, te whakarewa ātete, me ētahi atu tukanga paerewa. E taunakihia ana te whakamahi i te konganuku whakakī ERNiFeCr-1 (AWS A5.14) e ōrite ana mō ngā tono e hiahia ana ki te matū ōrite. Kāore e hiahiatia he whakamahana mua, ā, kāore e hiahiatia he maimoatanga wera i muri i te whakarewa mō te nuinga o ngā tono.
Ngā Āhuatanga Mīhini Pai– Ka mau tonu ngā āhuatanga miihini pai o te koranu mai i ngā pāmahana cryogenic ki raro ki te -184°C ki te 538°C (1000°F). Mā te mahi matao ka nui ake te kaha (tae atu ki te 1,035 MPa te kume) me te pupuri tonu i te ngāwari.
NACE MR0175 / ISO 15156 Whakatutukitanga– He pai te Incoloy 825 mō ngā tono ratonga kawa i roto i te umanga hinu me te hau, ātete ki te pakaru ahotea whanariki (SSC) me te pakaru hauwai (HIC) i roto i ngā taiao kei roto ko te H₂S.
