ASTM A333 Tau 6He rauemi ngongo maitai waro e whakamahia ana i roto i ngā mahi cryogenic me ētahi atu mahi e hiahia ana kia pakari te kōhao. Ka taea te whakamahi i roto i ngā taiao iti iho i te -45°C (-50°F) ā, e wātea ana i roto i ngā āhua tuia me ngā āhua whakarewa.
Ka taea te whakamahi i te ASTM A333 i roto i tetukanga kore hononga, tukanga whakarewa rānei.
Kua wehea te tukanga paipa maitai tui-kore ki te whakaotinga wera me te whakaotinga matao. Ā, me whakaata i runga ake i te tohu.
Ko ngā ngongo maitai tui kore te kōwhiringa tuatahi mō ngā taiao uaua, ngā āhuatanga taumaha, me te wā e hiahiatia ana he ngongo matotoru rawa.
Me tukatuka te ASTM A333 GR.6 kia rite ki tētahi o ngā tikanga e whai ake nei hei whakahaere i tōna hanganga moroiti:
● Te Whakaōrite: Whakamahanahia kia rite te pāmahana o te 815 °C, kātahi ka whakamatao ki te hau, ki te rūma whakamatao rānei o te oumu e whakahaerehia ana e te hau.
● Te whakamahana i muri i te whakataurite: I muri i te whakataurite, ka taea te whakamahana anō ki te pāmahana whakataurite tika i runga i te whakaaro o te kaihanga.
● Mō ngā tukanga maeneene, ka taea tēnei mā te whakahaere i ngā pāmahana o te mahi wera me ngā mahi whakaoti wera kia eke ai ngā pāmahana whakamutunga mai i te 1550 ki te 1750 °F [845 ki te 945 °C] kātahi ka whakamataohia ki te hau, ki roto rānei i te oumu e whakahaerehia ana e te āhuarangi mai i te pāmahana tīmatanga o te iti rawa o te 1550 °F [845 °C].
● I muri i te mahi wera me te whakaotinga o te maimoatanga wera, ka taea te whakamahana anō ki te pāmahana tika e ai ki te whakaaro o te kaihanga.
● Te tinei me te whakamahana: Hei utu mō tētahi o ngā maimoatanga o runga ake nei, ka taea te whakamahana i ngā ngongo tuitui o ngā Tau 1, 6, me te 10 mā te whakamahana ki te pāmahana ōrite o te 815 °C pea, ā, muri iho ka tinei ki te wai me te whakamahana anō ki te pāmahana whakamahana tika.
AMō ia whakahekenga o te 0.01% waro i raro i te 0.30%, ka whakaaetia kia piki ake te konupūmā o te 0.05% ki runga ake i te 1.06% ki te mōrahi o te konupūmā o te 1.35%.
CMā te whakaaetanga i waenganui i te kaihanga me te kaihoko, ka taea te whakanui ake i te rohenga mō te niobium ki te 0.05% i runga i te tātari wera me te 0.06% i runga i te tātari hua.
DHe ingoa rerekē ngā kupu Niobium (Nb) me Columbium (Cb) mō te huānga kotahi.
Āhuatanga Kume
| Tau | Te kaha o te kume | Te kaha tuku | Te whakaroa | |
| i roto i te 2 inihi, 50 mm rānei, iti rawa, % | ||||
| Roa | Whakapae | |||
| ASTM A333 Tau 6 | 415 MPa [60,000 psi] | 240 MPa [35,000 psi] | 30 | 16.5 |
Ko te roa o te whakaroa i konei te iti rawa taketake.
Ētahi atu Whakamātautau
He whakamātautau papatahi, he whakamātautau pānga hoki tā te ASTM A333, hei tāpiri atu ki te whakamātautau kume.
Ko ngā pāmahana whakamātautau pānga e whai ake nei mō te taumata 6:
