ASTM A213 T5(ASME SA213 T5) he ngongo maitai kore-honohono iti-konumohe kei roto ko te 4.00–6.00% chromium (Cr) me te 0.45–0.65% molybdenum (Mo), e tuku ana i te kaha pāmahana teitei me te ātete ki te waikura, ā, e whakamahia ana i roto i ngā taputapu pāmahana teitei, pēhanga teitei pērā i ngā kohua, ngā whakamahana nui, me ngā whakawhiti wera.
Ko te tohu UNS ko K41545.
I roto i te paerewa ASTM A213, hei tāpiritanga ki te T5, ko ngā koranu he rite te nui o te chromium me te molybdenum kei roto ko te T5b (UNS K51545) me te T5c (UNS K41245), he rerekē noa iho i te nui o te waro, te silicon, me ētahi atu huānga.
He kaihokohoko paipa rino koranu ngaio, pono hoki a Botop Steel, ā, ka taea e ia te tuku tere i ō kaupapa ki ngā momo paipa rino koranu, tae atu kiT9 (K90941),T11 (K11597),T12 (K11562),T22 (K21590), meT91 (K90901).
He pono te kounga o ā mātou hua, he utu whakataetae, ā, e tautoko ana i ngā tirotiro a te hunga tuatoru.

Kaihanga me te Āhua
Me hanga ngā paipa maitai ASTM A213 T5 e tetukanga maeneeneā, me tunua kia wera, kia matao rānei, e ai ki te whakaritenga.
Te Maimoatanga Wera
Me whakamahana anō ngā paipa maitai T5 mō te maimoatanga wera e ai ki ngā tikanga e whai ake nei, ā, me whakahaere motuhake te maimoatanga wera, me te whakamahana anō hoki mō te hanga wera.
| Tau | Momo Whakamahana | Pāpāho Whakamatao | Te Whakamahana, te Pāmahana rānei i raro i te Hiranga |

Ka whakapakeketia ētahi e te hau, arā, ka whakapakeketia ki tētahi taumata kāore e hiahiatia ana ina whakamataohia i roto i te hau mai i ngā pāmahana teitei, inā koa ko ngā maitai kei roto te chromium me te chromium o te 4% me te teitei ake. Nō reira, ko ngā mahi e whakauru ana i te whakamahana i aua maitai ki runga ake i ō rātou pāmahana tino nui, pērā i te whakarewa, te whakakoi, me te piko wera, me whai i te maimoatanga wera tika.
Āhua
Me kore he unahi i roto i ngā ngongo maitai whakarewa matao ASTM A213, ā, me pai mō te tirotiro. Kāore te nui o te waikura e kiia he unahi.
Me kore he unahi tāwharau o ngā ngongo maitai whakarewa-wera, ā, me pai mō te tirotiro.
Ahu
Ko ngā rahi o ngā ngongo ASTM A213 T11 me ngā matotoru o te pakitara he mea whakarite ki ngā diameter o roto mai i te 3.2 mm ki ngā diameter o waho o te 127 mm, ā, ko te matotoru iti rawa o te pakitara mai i te 0.4 mm ki te 12.7 mm.
Ka taea hoki te whakarato i ētahi atu rahi o ngā paipa maitai T11, ki te tutukihia ngā whakaritenga katoa o te ASTM A213.
Me whakamātau ia ngongo ki te whakamātautau hiko kore-whakangaro, ki te whakamātautau wai-pūmau rānei. Ko te momo whakamātautau hei whakamahi me whiriwhiri e te kaihanga, ki te kore e tohua tētahi atu mea i roto i te ota hoko.
Mā te paerewa ASTM A1016 ka taea te whakamahi i ngā whakamātautau kore-whakangaro hei whakakapi mō ngā whakamātautau waipū.
Ko ngā paipa maitai kore hononga ASTM A213 T5 e whakamahia nuitia ana i roto i ngā mahi ahumahi i raro i ngā āhuatanga pāmahana teitei me te pēhanga teitei, ā, he tino pai te mahi i roto i ngā ahumahi whakaputa hiko, matū, me te hinu me te hau.
Ko ngā tono noa ko:ngā ngongo pūwero, ngā ngongo whakawhiti wera, ngā paipa tukanga matū, ngā taputapu poihau me ngā oko pēhanga, me ngā paipa mō te kawe hau pāmahana teitei.
