He Tirohanga Whānui mō te Paipa Kowiri tira 321
Hei putanga whakarerekētanga o te SS304, ko te kowiri tira 321 (SS321) he kowiri tira austenitic kua whakapūmautia me te tāpiritanga o te titanium kia 5 ngā wā te nui ake o te waro. Mā te tāpiritanga o te titanium ka whakaitihia, ka āraihia rānei te aro o te maturuturunga carbide i te wā e whakarewahia ana, me ngā mahi i te awhe pāmahana 425-815°C. Ka whakapai ake hoki i ētahi o ngā āhuatanga i ngā pāmahana teitei. He tino ātete te SS321 ki te waikura me te waikura, ā, he kaha ngoki pai. E whakamahia ana i roto i ngā taputapu hinu, ngā paipa oko pēhanga, ngā whakamahana nui hihi, ngā bellews, me ngā taputapu maimoatanga wera pāmahana teitei.

Te Kaha o te Ngenge o te Ngongo Kowiri tira 321
I roto i ngā tono hihiri, he mea nui hoki kia whakaarohia te kaha o te ngenge. Ā, i tēnei āhuatanga, he paku painga ake te 321 SS i te 304 SS. Ko ngā rohe ngenge, te kaha rānei o te piko o ngā maitai kore waikura austenitic i roto i te āhua whakamahana he tata ki te haurua o te kaha kume. Ko ngā rohe kume me te manawanui noa mō ēnei koranu (kua whakamahana) kei te whakaatuhia i roto i te ripanga i raro nei:
| Koranu | Te Kukume Noa | Teihana Manawanui Noa |
| 304L | 68 ksi | 34 ksi |
| 304 | 70 ksi | 35 ksi |
| 321 | 76 ksi | 38 ksi |
Te Āheinga Whakarewa o te Ngongo Kowiri tira 321
He tino pai te āhua o te whakarewa o te SS321 me te TP321, kāore e hiahiatia he whakamahanatanga. Me rite te hanganga o te rauemi whakakī engari he nui ake te ihirangi koranu. Te pakaru o te wai i te rohe e pāngia ana e te wera: he iti te kaha e whakaurua ana. Te rahi o te kōhao angiangi. Ferrite ≥ 5%.
Ko ngā konganuku whakakī e taunakitia ana ko SS 321, 347, me te 348. Ko te hikohiko ko E347, ko E308L rānei [pāmahana ratonga < 370 °C (700 °F)].
Ngā tono o te ngongo maitai kore waikura 321
Ka taea te whakamahi i te Momo 321, 321H me te TP321 ki ngā wāhi kāore e taea te tukatuka otinga i muri i te whakarewa, pērā i ngā raina mamaoa me ngā paipa whakamahana nui me ngā pūnaha whakaputanga hau i roto i ngā miihini hurihuri me ngā tāpine hau me ngā pāmahana mai i te 425 ki te 870 °C (800 ki te 1600 °F). Me ngā raina werohanga wahie me ngā pūnaha waipēhi mō ngā waka rererangi me ngā waka rererangi.
