Te Tūhura i ngā Āhuatanga, ngā Whakamahinga, me ngā Painga o SAKYSTEEL
I te ao ahumahi o ēnei rā,ngā maitai kore waikurahe mahi nui tā rātou i roto i ngā rāngai hangahanga, pūngao, moana, me te matū. I roto i ngā momo maha,329 kowiri tirakua piki haere te aro mō tōna taurite tino pai ote kaha me te ātete ki te waikuraKo tētahi o ngāngā maitai kowiri tira takirua, te whakakotahi i ngā āhuatanga o ngā mea e ruaausteniticmewhanarikingā hanganga moroiti. Mā tēnei hanganga ahurei ka taea te mahi pai i roto i ngā taiao uaua e pakaru ai pea ngā maitai kore waikura noa.
I roto i tēnei tuhinga, ka rukuhia e mātou te āhua o te maitai kore waikura 329, tōna hanganga, ōna āhuatanga matua, ōna āhuatanga miihini, me ngā whakamahinga ahumahi matua. Hei kaiwhakarato ao mō ngā maitai kore waikura kounga teitei,SAKYSTEELe whakarato ana i ngā māramatanga ki te take e noho nei tēnei koranu hei whiringa pai mā ngā miihini me ngā kaihanga puta noa i te ao.
1. Tirohanga Whānui o te 329 Kowiri tira
329 kowiri tira, e mōhiotia ana hoki koUNS S32900, hekowiri tira takiruahe rite tonu te nui o te ferrite me te austenite. Mā tēnei hanganga moroiti taurite ka puta he huinga okaha kume teitei, ātete pai ki te pakaru waikura ahotea hauota, mehe ātete pai ki te waikura o te poka me te kapitiki te whakataurite ki ngā momo austenitic paerewa pēnei i te 304, i te 316 rānei.
I whakawhanakehia tuatahitia hei whakamahi i roto ingā ahumahi tukatuka moana me te matū, he wero tonu te waikura i puta mai i te hauota, te waikawa, me te wai moana. Nā tōna hanganga takirua, ka tukuna e te maitai kore waikura 329 ngā mea e ruate roa o te mahi miihini me te mahi waikura, he mea pai mō ngā taiao pukuriri me ngā taiao pēhanga teitei.
2. Te Hanganga Matū
Ko te hanganga matū noa o329 kowiri tirakei roto:
-
Konukōmiuma (Kr):23–28%
-
Nikara (Ni):2.5–5%
-
Molibdenuma (Mo):tae atu ki te 1.5%
-
Manganēhi (Mn):≤1.0%
-
Hiraka (Si):≤1.0%
-
Waro (C):≤0.08%
-
Hauota (N):≤0.2%
Mā tēnei hanganga ka nui te koranuchromiumā, he tauritenikarangā ihirangi, e whakau tahi ana i te hanganga moroiti takirua, e whakarei ake ana hoki i te ātete ki te waikura. Ko te tāpiri omoripenemuka whakapai ake i te ātete ki te waikura ā-rohe pērā i te pakaru me te kapiti, inā koa i roto i ngā wairewa kei roto he pūhaumāota.
3. Ngā Āhuatanga Hanganga Moroiti me te Whakarewa
Ko te āhua takirua o te maitai kore waikura 329 ka hua ake hehanganga moroiti rua-wāhanga:
-
Ferrite (α)ka whai wāhi ki te kaha me te ātete ki te pakaru waikura ahotea.
-
Austenite (γ)ka whai wāhi ki te pakari me te ngāwari.
Ko te hanganga iti ka tiakina mā te maimoatanga wera whakahaere i te wā e hangaia ana. Ka tukuna e te hanganga takirua-wāhangae rua te kaha whakaputa o ngā maitai kowiri tira raupapa-300, me te pupuri tonu i te roa me te āheinga hanga e tika ana.
I ngā pāmahana tiketike, me āta tupato kia kore ai e pāngia e tete hanganga o te wāhanga sigma, ka taea te whakaiti i te pakari me te ātete ki te waikura. Nō reira, he mea nui te tukatuka me te whakamahana whakahaere kia mau tonu ai ngā āhuatanga tino pai.
4. Ngā Āhuatanga Mīhini
He pai te taurite o te kaha ā-pūkaha me te ngāwari o te maitai kore waikura 329. Ko ngā uara ā-pūkaha noa (i roto i te āhua whakamahana) ko:
-
Kaha kume:≥ 620 MPa
-
Te kaha o te hua (0.2% te rerekētanga):≥ 450 MPa
-
Te roa:≥ 25%
-
Te pakeketanga (HB):≤ 250
Nā te huinga o te kaha kume me te kaha kume, he rauemi pai rawa atu te 329 mō ngā tono kawenga me ngā tono hanganga e tino hira ana te ātete ki te waikura.
5. Ātete ki te Waikura
Ko tētahi o ngā painga nui o329 kowiri tirako tōnaātete tino pai ki te waikuraHe pai te mahi i ngā mea e ruangā taiao whakahāora me te whakaiti, inā koa he āwangawanga te pānga ki te hauota. Ko ngā āhuatanga matua o te waikura ko:
-
Ātete ki te Pakū Waikura o te Hauhā:Nā tōna āhua ferritic ka nui ake tōna ātete i ngā momo austenitic pēnei i te 316L.
-
Ātete Pai ki te Pōkākā:Nā te nui o te chromium me te molybdenum i roto, ka ātete ki te pakaru i roto i te wai moana me ngā taiao tukatuka matū.
-
Ātete Pai ki te Pakaru o te Āwangawanga o te Whāriki:He mea pai mō ngā taiao hinu me te hau kei roto ko te hauwai whanariki (H₂S).
-
Ātete ki te Waikura Ā-Whānui:Mā te maimoatanga wera tika ka ārai i te maturuturunga o te warowaihā, ā, ka pumau te waikura mō te wā roa.
Nā ēnei take, he pai ake te maitai kore waikura 329 i roto i ngāngā hanganga moana, ngā tipu tango tote, me ngā papa hinu tai.
6. Te Hanga me te Āheitanga ki te Mīhini
Ahakoa329 kowiri tirahe kaha ake i te nuinga o ngā maitai kore waikura austenitic, ka taea tonui mīhinihia, i whakarewahia, ā, i hangaiamā te whakamahi i ngā tikanga tika:
-
Mīhini:Me whai taputapu kaha, me ngā taputapu koi hoki nā te mea he tino kaha. E taunakihia ana kia puhoi ngā tere me ngā whakatakotoranga pakari.
-
Te whakarewa:Ka taea te whakarewa mā roto i ngā tukanga noa pēnei i te TIG, MIG, me te SMAW. Heoi, he mea nui te whakahaere i te wera whakauru me te pāmahana i waenga i te whakawhiti hei pupuri i te taurite ā-wāhanga.
-
Te Hanga:Nā te kaha ake, tera pea he nui ake te kaha e hiahiatia ana mō te hanga i tērā i te 304, i te 316 rānei, engari ka taea tonu te mahi hanga matao.
I muri i te hangahanga,te whakamahana otingae mahia pinepine ana hei whakaora i te ātete me te pakari o te waikura.
7. Ngā Whakamahinga o te 329 Kowiri tira
Ko te huinga ahurei ote kaha, te ātete ki te waikura, me te mahi ngengee hanga ana i te 329 kowiri tira e tika ana mō te whānuitanga o ngā tono ahumahi:
a) Moana me te Moana-a-Kiwa
I whakamahia i roto ingā paipa wai moana, ngā pou poroporo, me ngā whakawhiti wera, ka ātete te 329 ki te waikura i roto i ngā taiao tote me te wai tote.
b) Te Tukatuka Matū
He ātete ki ngā matū kaha, ngā waikawa, me ngā pūhaumāota, ā, he mea tino pai mōngā tāke rokiroki matū, ngā whakawhiti wera, me ngā mīhini whakapūhau.
c) Ahumahi Hinu me te Hau
E whakamahia whānuitia ana i roto ingā paipa, ngā takirere, ngā papu, me ngā taputapumō ngā taiao keri taiwhenua me ngā taiao ratonga hau-kawa e hiahia ana kia tutuki i ngā whakaritenga NACE MR0175.
d) Te Whakaputa Hiko
I whakamahia i roto ingā pūnaha wai whāngai pūweromengā whakapūmaue hiahia ana ki te ātete nui ki te waikura me te tauine.
e) Te Pūmua me te Pepa
I whakamahia i roto ingā mīhini keri, ngā mīhini horoi mā, me ngā pūnaha whakaora wera, te wāhi e nui ai te pānga ki te pūhaumāota me te waikawa.
f) Te Maimoatanga Wai me te Whakakorenga Tote
He pai mōngā taputapu tango tote, ngā papu, me ngā tātarinā tōna ātete ki ngā katote pūhaumāota me te waikura tote.
8. Te Whakataurite ki Ētahi Atu Rino Kowiri tira
Ina whakaritea ki ngā momo paerewa, e whakaatu mārama ana te maitai kore waikura 329 i tōna taurite pai o ngā āhuatanga miihini me te waikura:
-
Ki te 304:He kaha nui ake, he ātete hoki ki te hauhāora.
-
Ki te 316:He ātete pai ake ki te waikura i ngā poka me te ahotea.
-
Ki te 2205 (UNS S31803):He iti ake te ihirangi molybdenum, engari he pai te mahi i roto i ngā āhuatanga pūhaumāota waenga i te utu iti iho.
Ko te toenga nei ka 329kōwhiringa utu-whai huahe mea nui te kaha me te ātete ki te waikura, engaringā kōeke tino takirua(pērā i te 2507) tērā pea ka nui rawa te whakaritenga, ka nui rawa rānei te utu.
9. Te Maimoatanga Wera me te Āheinga Mahi
He mea nui te maimoatanga wera hei whakahaere i te taurite ā-wāhanga me te mahi ā-pūkaha:
-
Te Whakamahana Otinga:I te nuinga o te wā kei te 1050–1120°C, ā, muri iho ka tere te whakamatao kia mau tonu te hanganga takirua.
-
Whakaora i te ahotea:I te nuinga o te wā ka mahia i raro i te 300°C hei karo i te ua.
Mā te āta whakahaere i ngā huringa wera ka ārai i te hanganga o ngā āhua kino o waenga-whakarewa. Mā te whakamahana tika ka whakaratohia te hanganga whakamutungate ātete me te pakari mōrahi o te waikura.
