Ko nga whenua kowiri tira kowiri tira te whakatinanatanga o te paerewa mana o te maataki rino nga waahanga matua o te tepu 321 kowiri tira e rite ana ki te whare 1Cr17Ni9Ti, 321 he tino rite ki te 304 te mahi kowiri tira, engari na te taapiri o te whakarewa titanium, kia pai ake ai te aukati. ki te waikura rohe witi me te kaha o te pāmahana teitei. Na te taapiri o te whakarewa titanium, he pai te whakahaere i te hanganga o te chromium carbide. Ko te 321 kowiri tira he pai ake te mahi Stress Rupture me te teitei ake o te pāmahana Creep Resistance i roto i te ahotea me nga taonga miihini atu i te 304 kowiri tira. 321 Ka whakamahia nga reera kowiri tira mo te kaha o te atete ki te weriweri rohe o te witi Ko nga kaupapa mahi matua 304 te tira kowiri tira GB 0Cr18Ni9, GB 0Cr18Ni9 hei kaupapa o te kowiri tira, he pai te aukati, te wera wera, te iti o te kaha o te pāmahana me nga taonga miihini. ; He pai te tarai, te piko me etahi atu tukatuka wera, kaore he ahuatanga whakamaroke wera (kare he autō, te whakamahi i te pāmahana -196 ℃ ~ 800 ℃). Ko te 321 he kowiri tira e rite ana ki te whare 1Cr17Ni9Ti, 321 he tino rite ki te 304 te mahi kowiri tira, engari na te taapiri o te whakarewa Titanium, kia pai ake ai te aukati ki te waikura rohe witi me te kaha o te wera. Na te taapiri o te whakarewa titanium, he pai te whakahaere i te hanganga o te chromium carbide. Ko te 321 kowiri tira he pai ake te mahi Stress Rupture me te teitei ake o te pāmahana Creep Resistance i roto i te ahotea me nga taonga miihini atu i te 304 kowiri tira. 321 Kowiri tira ka whakamahia i roto i te witi tiketike rohe waikura ātete o te matū, waro, ahumahi hinu i roto i te mara o tuwhera wera ātete paipa me te maimoatanga wera he paipa uaua. 316 kowiri tira kowiri tira GB 0Cr17Ni12Mo2 0Cr17Ni12Mo2, na te taapiri o Mo, na reira he pai rawa atu te aukati o te waikura, te aukati o te hau me te kaha o te pāmahana teitei, ka taea te whakamahi i raro i nga tikanga kino; 316 kowiri tira i whakamahia i roto i: te wai moana, te matū, te tae, te pepa, te waikawa oxalic, te tongi me etahi atu taputapu whakaputa; Ko te 316L kowiri tira GB 00Cr17Ni14Mo2 00Cr17Ni14Mo2, i te mea ko te 316L kowiri tira i tua atu i te 316 kowiri tira he rite tonu nga ahuatanga, he pai ake i te 316 te rohe o te witi; I tua atu, ko te taapiri o te huānga molybdenum ka taea te whakapai ake i tona aukati ki te waikura intergranular me te waikura ahotea waikura, me te whakaiti i te ahua o te pakaru wera i te wa o te whakapiri. Ko te 316L te kowiri tira e whakamahia ana i roto i te: he maha nga wa e whakamahia ana i roto i te wai parakore, te wai parakore, te rongoa, te ranu, te winika me etahi atu whakaritenga hauora, ko te mahi waikura reo he wa kaha, 316 kowiri tira te whakamahi motuhake ki te waikura rohe witi he whakaritenga motuhake o nga hua. Ko te 310S kowiri tira he tikanga paerewa o te kowiri tira i roto i te United States, ko te tapanga o te whare ko (2520) 0Cr25Ni20, he ahua o te kowiri tira austenitic, ko te S i roto i te 310S e pa ana ki te whakamahinga motuhake o te kowiri tira. 0Cr25Ni20 (310S) nga ahuatanga -- teitei te wera o te werawera, te kaha o te wera. Whakamahi - putorino putorino Bellows, ngaruiti oumu Whakawera, Tube, teitei te pāmahana oumu tōngāmimi, oumu tahutahu me etahi atu whakaritenga o te ātete wera o vaolo kowiri tira. I te nuinga o te waa ** ka kite i te 304, 316 he kowiri tira he penei, 304 te waahanga paerewa ko te 18% chromium me te 8% nickel, e mohiotia ana ko te 18-8 te kowiri tira. Ko nga ahuatanga o tenei momo kowiri tira he kore-autō, e kore e taea te whakarereke i te tikanga maimoatanga wera o te hanganga metallography, he pai te tukatuka, na te mea ko te huānga koranu - nickel, no reira he pai ake te aukati o te waikura i te chromium anake (kao nickel) o era atu momo e rua o te kowiri tira. Ko nga whakamahinga matua o te 300 raupapa kowiri tira kowiri: te nuinga o te whakamahi i roto i te hinu, te matū, te rongoa, te tongi matū, te hiko hiko me etahi atu ahumahi o nga momo mahi i runga i te paipa. I roto i nga whakaaro o nga tangata noa, ko te mea e kiia nei ko te kowiri tira e tohu ana ki te 300 nga kowiri tira (inaa ko te 304 nga kowiri tira).
