Ko te rino kowiri he 10.5% te iti o te ihirangi chromium, na reira ka kaha ake te atete ki nga taiao wai pirau me te waikura. He tino pai te waikura me te mau kakahu, he pai te mahi miihini, he rongonui mo tona ahua rerehua. Ko nga whakarewanga whakangao kowiri tira he "waipara-atete" ka whakamahia i roto i nga taiao wai me nga kohu i raro i te 1200°F (650°C) me te "wera-aukati" ina whakamahia i runga ake i tenei pāmahana.
Austenitic kowiri tirae 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). I etahi waahi, ko te austentite kowiri tira ka kiia ko te 300 raupapa kowiri tira. 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.
Ka taea hoki e Austenitic kowiri tira te whakaputa whakarewa. 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 7.93 g / 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.
