He paipa kowiri tira tino angiangi-taiepa kei roto i nga taonga
304 putorino kowiri tira nui diameter ko te ahua o te koranu maitai teitei e taea te ātete te waikura i roto i te rangi waikura matū reo ranei. 304 paipa kowiri tira he mata ataahua, me te pai te ātete waikura. Ehara i te mea me whai maimoatanga mata penei i te whakakikorua tae, engari ka tino purei ki te mahinga o te mata o te kowiri tira ka whakamahia i roto i te maha o nga waahanga o te maitai.
9% nickel, 19% chromium, he kowiri tira, he tira wera-wera
Ko te tikanga ka kiia he kowiri tira. Ko nga taonga o nga mema ko te 13 chromium maitai, 18-8 chromium nickel maitai me etahi atu maitai koranu teitei. Mai i te tirohanga o te metallography, na te mea he kowiri tira kei roto i te chromium, ka hangaia he kiriata chromium tino angiangi ki runga i te mata, ka wehea mai i te hāora ka uru mai ki roto i te maitai me te whai waahi ki te aukati i te waikura. Kia mau tonu ai te parenga waikura o te kowiri tira, me nui ake i te 12% te chromium te rino. Ko te 304 he kowiri tira o te ao, e whakamahia whanuitia ana ki te hanga taputapu me nga waahanga e hiahia ana kia pai te mahi matawhānui (te aukati i te waikura me te hangai). Ko te 304 kowiri tira he parani kowiri tira i hangaia e ai ki nga paerewa ASTM Amerika. Ko te 304 he rite ki te 0Cr19Ni9 (0Cr18Ni9) he kowiri tira i Haina. 304 kei roto 19% chromium me te 9% nickel. Ko te 304 te tino kowiri tira e whakamahia nuitia ana me te tira wera-wera. Mo nga taputapu hanga kai, nga taputapu matū Xitong, te kaha karihi, me etahi atu whakaritenga hanganga matū o te 304 kowiri tira C Si Mn ps Cr Ni (nickel) Mo SUS304 ≤ 0.08 ≤ 1.00 ≤ 2.00 ≤ 0.05 ≤ 0.03-20.05 ≤ 0.03-20.5
