Ko nga raupapa kowiri tira e whakamahia nuitia ana ko te 304 kowiri tira me te 316 kowiri tira.304 kowiri tira ko austenitic kowiri tira, he kowiri tira maha, e whakamahia whānuitia ana ki te hanga taputapu e hiahia ana te mahi matawhānui pai (te waikura parenga me te hanga) Me nga waahanga.Kia mau tonu ai te parenga waikura o te kowiri tira, me nui ake i te 18% te chromium me te 8% nickel te rino.Ko te 304 kowiri tira he karaehe o te kowiri tira i hangaia i runga i te paerewa ASTM Amerika.
Hangaia te Whakapaipai Mata Ki te Kowiri tira Kowiri tira
I roto i te ahua o te otinga totoka, ko te kaha kaha o te 304 kowiri tira he 550MPa, me te pakeke ko te 150-160HB.Ko te 304 e kore e taea te whakakaha i te maimoatanga wera, engari ka taea anake ma te mahi makariri.Heoi, i muri i te mahi makariri, i te wa e pai ake ana te kaha, ka tino heke tona kirihou, te pakari me te aukati waikura.
304 Pepa Kowiri/Paareti
He pai ake te parenga waikura o te 304 kowiri tira i tera o te 430 he kowiri tira, engari he iti ake te utu i te 316 kowiri tira, na reira ka whakamahia nuitia i roto i te ao, penei i etahi taputapu tepu kowiri tira teitei, nga raima kowiri tira o waho, me era atu.
