304 / 304L Kowiri tira ngongo Tuinga
Whakataki Hua
Ko nga kowiri tira 304 (S30400) me te 304L (S30403) he rereke o te 18 paiheneti chromium – 8 paiheneti nickel austenitic koranu, ko te koranu tino mohio me te nuinga o te whakamahi i roto i te whanau kowiri tira. Ko te 304/L he kowiri tira he pai rawa te hanga. Ko tana ngawari ka taea te hanga ngawari mo te pupuhi, te piko me te kowiri. Ko te pai o te miihini me te iti o te whanariki e whakatairanga ana i te pai o te weldability ki nga tono e hiahia ana.
Ko te kaha teitei, te pai o te aukati waikura me te iti o te ihirangi waro ka whai hua te Alloy 304 me te 304L Kowiri tira mo nga tono e hiahiatia ana te whakapiri. Ko nga whakamahinga ko nga hangahanga hoahoanga me te kuti, nga waahanga paiherea o te matū, te kakano, te pepa, te rongoa me nga taputapu tukatuka ahumahi matū.
Ko etahi atu painga ko te aukati ki te haukura, te pai o te hanga, te ngawari o te hanga me te horoi, te kaha pai ki te tauwehenga taumaha me te uaua pai i te pāmahana cryogenic Mo nga taiao tino kino, he pai ake te ihirangi iti o te Momo 304L na te mea he nui ake te mate ki te waikura intergranular.
Momo 304L kowiri tira he putanga waro-iti ake o te maitai 304koranu. Ko te iti o te waro i roto i te 304L ka whakaiti i te rerenga carbide kino, kino ranei na runga i te whakapiri. Ka taea e 304L te whakamahi "he paiherea" i roto i nga taiao kino kino, a ka whakakorehia te hiahia mo te whakahiato.
He iti ake nga ahuatanga miihini o tenei karaehe i te karaehe paerewa 304, engari e whakamahia nuitia ana na te kaha o te mahi. Pērā i te Momo 304 he kowiri tira, ka whakamahia ki te mahi pia me te hanga waina, engari mo nga kaupapa i tua atu i te ahumahi kai penei i nga ipu matū, te keri me te hanga. He pai mo te whakamahi i nga waahanga whakarewa penei i nga nati me nga raka e pa ana ki te wai tote.
