Austenitic kowiri tira e pā ana ki te kowiri tira me te hanganga austenitic i te pāmahana rūma. Ko te kowiri tira Austenitic tetahi o nga karaehe e rima o te kowiri tira ma te hanga tioata (me te ferritic, martensitic, duplex me te ua whakapakeke). Ina kei roto i te maitai te 18% Cr, 8% -25% Ni, me te 0.1% C, he hanganga austenite pumau. Austenitic chromium-nickel kowiri tira kei roto i te maitai 18Cr-8Ni rongonui me te maitai raupapa Cr-Ni teitei i whakawhanakehia ma te whakauru i te ihirangi Cr me Ni me te taapiri Mo, Cu, Si, Nb, Ti me etahi atu waahanga i runga i tenei kaupapa. Ko te kowiri tira Austenitic he kore-aukume, he nui te uaua me te kirihou, engari he iti tona kaha, a kaore e taea te whakapakari i roto i te huringa wahanga. Ka taea anake te whakapakari ma te mahi makariri. Mena ka taapirihia nga huānga penei i te S, Ca, Se, Te, he pai nga ahuatanga o te miihini.

Nga Waahanga Aunoa i Makahia e te Makanga Whakangao o Autenitic Stainless Steel
Ka taea hoki e Austenitic kowiri tira te whakaputa whakarewa, te tikanga natukanga makanga haumi. Hei whakapai ake i te rere o te rino whakarewa me te whakapai ake i te mahi whakarewa, me whakatika te hanganga koranu o te rino whakarewa ma te whakanui ake i te ihirangi silicon, te whakanui i te awhe o te chromium me te nickel content, me te whakanui ake i te rohe o runga o te whanariki huānga poke.
Austenitic kowiri tira kia totoka-wairewa tukinotia i mua i te whakamahi, kia rite ki te whakanui i te otinga totoka o te rerekē precipitates pērā i carbide i roto i te maitai ki te matrix austenite, i te homogenizing hoki te hanganga me te whakakore i te ahotea, kia rite ki te whakarite pai te waikura ātete me āhuatanga pūkaha. Ko te punaha maimoatanga otinga tika ko te whakamahana wai i muri i te whakamahana i te 1050～1150 ℃ (ko nga wahi angiangi ka taea te whakamatao i te hau). Ko te pāmahana maimoatanga otinga ka whakawhirinaki ki te tohu o te whakakotahitanga o te maitai: Ko nga tohu rino molybdenum-kore, iti-molybdenum ranei kia iti ake (≤1100 ℃), me teitei ake nga tohu whakarewa penei i te 00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, me etahi atu. 1080～1150) ℃).
Austenitic 304 pereti rino kowiri tira, e kiia ana he kaha ki te kawe mai i te waikura me te waikura, he pai te kirihou me te uaua, he pai mo te tarai me te hanga. Ki te kiato o 7.93g/cm3, 304 kowiri tira ko te tino noa kowiri tira, mohiotia hoki rite 18/8 kowiri tira i roto i te ahumahi. Ko ona hua whakarewa he atete ki te wera nui me te pai o nga taonga tukatuka, na reira ka whakamahia nuitia i roto i te ahumahi me nga ahumahi whakapaipai taonga me nga ahumahi kai me te hauora.
