Ngā Painga Matua o Incoloy 800H
Kaha Tino Pai mō te Pakaru-ngoki– Ko te tohu "H" e tohu ana kua hangaia motuhake a Incoloy 800H mō te mahi ngoki i te pāmahana teitei. Me te ihirangi waro kua whakahaeretia (0.05-0.10%) me te rahi o te witi (ASTM 5, he matotoru ake rānei), ka whakaratohia e Incoloy 800H te kaha ngoki-pakaru kua tino pai ake ki te Incoloy 800 paerewa i ngā pāmahana neke atu i te 815°C. I te 870°C, ko te kaha ngoki-pakaru 1,000-haora he 45 MPa — he nui ake i te paerewa 800.
Ātete Waikura Pai rawa atu– Ka hangaia e Incoloy 800H he unahi waikura Cr₂O₃ piripono e whakarato ana i te tiakitanga pai rawa atu i roto i ngā hau whakahāwea tae atu ki te 1093°C (2000°F). Ko te tāpiri konumohe (0.15-0.60%) ka whakarei ake i te ātete whakahāwea mā te whai wāhi ki te paparanga Al₂O₃ tiaki i te atanga whakarewa-waikura, ka whakapai ake i te piri unahi me te aukati i te pakaru i raro i ngā āhuatanga huringa wera.
Rahi o te Wiri Whakahaeretia– Ka hangaia te Incoloy 800H me te rahi o te kōhao kua whakamanahia o te ASTM 5, te rahi rānei o te kōhao. Mā te hanganga kōhao rahi ka whakaitihia te reti o te rohe kōhao i ngā pāmahana teitei, ka whakarato i te ātete ngoki pai rawa atu. He rerekētanga matua tēnei mai i te Incoloy 800 paerewa, kāore nei he whakaritenga mō te rahi o te kōhao.
Ātete ki te Warburization– I roto i ngā taiao whai waro nui (ngā oumu pakaru ethylene, ngā mīhini whakahou mamaoa), ka ātete pai ake a Incoloy 800H ki te whakakākahu i te waro i te nuinga o ngā koranu ātete wera. Mā tēnei ka ārai i te puehu me te pakaru o te konganuku, ka roa ake te ora o ngā ngongo i roto i te ratonga hinu-matū ina pakaru pea ngā ngongo maitai waro i roto i ngā marama.
Ātete Pai ki te Waikawa Hauota me ngā Hauota– Ko te nui o te nikara (30-35%) e whakarato ana i te ātete pai ki te pakaru waikura o te ahotea hauota, ko te nui o te chromium e whakarato ana i te ātete pai ki te waikawa hauota, e pai ai te Incoloy 800H mō ngā taputapu tipu waikawa hauota.
He Āheitanga Whakarewa Pai rawa atu– Ka taea te whakarewa ngāwari i te Incoloy 800H 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. Kāore e hiahiatia he maimoatanga wera i muri i te whakarewa mō te nuinga o ngā tono.
