I te wā e whiriwhiri ana i ngā rauemi kowiri tira, ko te 3Cr12 me te 410S ngā kōwhiringa e rua e whakamahia whānuitia ana. Ahakoa he kowiri tira e rua, he rerekētanga nui kei roto i te hanganga matū, te mahi, me ngā wāhi tono. Ka rukuhia e tēnei tuhinga ngā rerekētanga matua i waenga i ēnei pereti kowiri tira e rua me ā rāua tono, hei āwhina i a koe ki te whakatau whai whakaaro mō ō kaupapa.
He aha te maitai kore waikura 3Cr12?
Pepa maitai kore waikura 3Cr12He kowiri tira ferritic kei roto ko te 12% Cr, he rite ki te taumata Pākehā 1.4003. He kowiri tira ferritic ohanga e whakamahia ana hei whakakapi i te maitai waro pania, te maitai huarere me te konumohe. He ngāwari te tukatuka me te hanga, ā, ka taea te whakarewa mā te hangarau whakarewa tikanga. Ka taea te whakamahi hei hanga: ngā anga waka, ngā anga waka, ngā pekepeke, ngā whitiki kawe, ngā mata mata, ngā oko kawe waka, ngā ipu waro, ngā ipu me ngā tāke, ngā auahi, ngā paipa hau, me ngā uhi o waho, ngā panera, ngā ara hikoi, ngā arawhata, ngā rēri, me ētahi atu.
He aha te maitai kore waikura 410S?
410S maitai kore waikuraHe whakarerekētanga waro-iti, kāore e whakapakeketia te maitai kowiri tira martensitic 410. Kei roto tata ki te 11.5-13.5% te chromium me ētahi atu huānga iti pēnei i te manganese, te phosphorus, te whanariki, te silicon, me ētahi atu nickel. Ko te iti o te ihirangi waro o te 410S ka whakapai ake i tōna āheinga whakarewa me te whakaiti i te tūponotanga o te whakapakeketanga, te ngatata rānei i te wā whakarewa. Heoi, ko te tikanga hoki tēnei he iti ake te kaha o te 410S ki te whakataurite ki te paerewa 410. He pai te ātete ki te waikura, inā koa i roto i ngā taiao ngawari, engari he iti ake te ātete ki ngā maitai kowiri tira austenitic pēnei i te 304, i te 316 rānei.
Te Hanganga Matū o te Pereti Rino Ⅰ.3Cr12 me te 410S
E ai ki te ASTM A240.
| Tau | Ni | C | Mn | P | S | Si | Cr |
| 3Cr12 | 0.3-1.0 | 0.03 | 2.0 | 0.04 | 0.030 | 1.0 | 10.5-12.5 |
| 3Cr12L | 0.3-1.0 | 0.03 | 1.5 | 0.04 | 0.015 | 1.0 | 10.5-12.5 |
| 410S | 0.75 | 0.15 | 1.0 | 0.04 | 0.015 | 1.0 | 11.5-13.5 |
Ngā Āhuatanga o te Pereti Rino Ⅱ.3Cr12 me te 410S
3Cr12 Kowiri tiraHe pakari me te ngāwari ki te whakarewa, he pai mō ngā momo tikanga tukatuka. He kaha taurite me te ātete ki te kakahu, e āhei ai te tu atu i ētahi taumahatanga miihini.
410S Kowiri tira:He pakeke ake, he pai mō ngā mahi pāmahana teitei, engari he ngoikore te āheinga whakarewa. Nā tōna kaha me tōna ātete wera ka tino pai i roto i ngā āhuatanga pāmahana teitei.
| Tau | Rm(MPa) | Te Pakaritanga Nui (BHN) | Te whakaroa |
| 3Cr12 | 460 | 220 | 18% |
| 3Cr12L | 455 | 223 | 20% |
| 410S | 415 | 183 | 20% |
Ngā Wāhi Whakamahinga Pereti Rino Ⅲ.3Cr12 me 410S
3Cr12E whakamahia whānuitia ana i roto i ngā taputapu matū, ngā taputapu tukatuka kai, me ngā rauemi hanga. Nā tōna ātete pai ki te waikura, he mea tino pai mō ngā taiao makuku me te waikawa.
410SE whakamahia whānuitia ana i roto i ngā wāhanga tāpine, ngā poiha, me ngā whakawhiti wera i roto i ngā taiao pāmahana teitei. He pai mō ngā tono e hiahia ana ki te ātete wera me te ātete kakahu.
Whakarāpopototanga Whakataurite
Ngā Āhuatanga Matua o te 3Cr12:
• Te Hanganga: Te nui o te chromium i roto i te 11.0–12.0%, te nui o te waro i roto i te ≤ 0.03%.
• Ātete ki te Waikura: He pai mō ngā taiao waikura ngawari, pērā i ngā wāhanga hanganga, ngā taputapu keri, me ngā tono ahumahi whānui.
• Āheitanga Whakarewa: He pai te mahi whakarewa nā te iti o te ihirangi waro.
| Paerewa | Tau |
| Paerewa o Awherika ki te Tonga | 3Cr12 |
| Paerewa Pākehā | 1.4003 |
| Paerewa o Amerika | UNS S41003 (410S) |
| Paerewa o te Ao | X2CrNi12 |
• 410SHe pakeke ake engari he paku iti ake te pakari, kāore he titanium, he ngāwari te whakarewa, ā, he pai mō ngā tono whānui e ātete ana ki te waikura.
• 3Cr12He iti te waro, he iti te utu, he pai mō ngā taiao waikura ngawari, he pai hoki te kaha ki te whakarewa.
