Ngā Painga Matua o Monel 400
Te Ātete Tino Pai ki te Waikura o te Moana– E mōhiotia whānuitia ana a Monel 400 mō tōna ātete tino pai ki ngā taiao wai moana me te moana. He tino pai te ātete o te koranu ki te waikura o ngā poka me ngā kapiti, ā, koinei te rauemi pai mō ngā paipa wai moana, ngā toki papu, ngā toki poroporo, me ngā taputapu papaaho moana. Kāore i rite ki te nuinga o ngā maitai kore waikura, he ātete a Monel 400 ki te pakaru waikura ahotea i puta mai i te hauota i roto i te ratonga wai moana.
Ātete Waikawa Hydrofluoric Tino Pai– Ko te Monel 400 tētahi o ngā rauemi ruarua ka taea te whakahaere i te waikawa hauwaiwai puta noa i te whānuitanga o te kukū. Nā te nui o te nikara e ātete ana ki te waikawa HF, koia te rauemi paerewa mō ngā taputapu whakahaere waikawa HF i roto i ngā wāhanga tukatuka matū me te alkylation.
He Ātete Waikawa Whakaiti Pai– He tino pai te ātete o te koranu ki te waikura i roto i ngā waikawa whakaiti pēnei i te waikawa hauwai, te waikawa whanariki, me te waikawa phosphoric, mena kāore he momo waikura. Ka whai wāhi te nui o te parahi ki te ātete i roto i ēnei taiao ka pakaru te nuinga o ngā maitai kore waikura.
He Āheitanga Whakarewa Pai rawa atu– Ka taea te whakarewa ngāwari i te Monel 400 mā te whakamahi i te TIG, MIG, te whakarewa ātete, me ētahi atu tukanga paerewa. E taunakihia ana te whakamahi i te konganuku whakakī ōrite (AWS A5.14 ERNiCu-7). Kāore e hiahiatia he whakamahana i mua i te nuinga o te wā, ā, kāore e hiahiatia he maimoatanga wera i muri i te whakarewa mō te nuinga o ngā mahi.
Ngā Āhuatanga Mīhini Pai– Ka mau tonu te pai o ngā āhuatanga hangarau o te koranu mai i ngā pāmahana cryogenic ki raro ki te -184°C ki te 260°C (500°F) mō ngā tono whakamahana puna. Ka whakanui ake te mahi matao i te kaha me te pupuri tonu i te ngāwari.
NACE MR0175 / ISO 15156 Whakatutukitanga– He pai te Monel 400 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.
Kore-Aukume– Kāore he aukume i roto i te koranu, nō reira he pai mō ngā mahi e tika ana kia karohia te pokanoa aukume, pērā i ngā taputapu moana.
